When is the decoration wall paint prone to cracking? How many degrees does it take for the temperatu

The time when the decoration wall paint is easy to crack: the indoor temperature of the wall paint should not be lower than 5. In winter, when the temperature is low and the air humidity is high on rainy days, it is necessary to minimize the delivery of home improvement materials and architectural coatings on rainy days.

The temperature is below 0 is not suitable for interior decoration, the ambient temperature of the often used mixed-color exterior wall paint construction should be about 0, the ambient temperature of architectural coating is not lower than 5, and the ambient temperature of topcoat application should not be lower than 8. Therefore, in winter, the decoration project should ensure that the indoor temperature is at least not lower than 5. In particular, painters need to pay more attention to "cold protection and warmth", and then open the windows and doors to exhaust the air after they are completely dried.

The temperature of wall paint brushing is generally above 5 degrees can be painted on the wall, below 5 degrees is not recommended for engineering construction, and it is best to build the project on a sunny day. Cracks in the concrete are uneven, and the temperature shift is too large, causing gaps in the wall. Such things generally cannot be repaired by interior decoration, and special engineering and construction staff should be invited to solve them.

The processing technology is not standardized. The mixed mortar is not mixed and prepared reasonably, and the concrete layer is not dried to batch putty, and the wall cracking is easy to occur in the future, such as the putty powder is too thick, and the crack that is wide in the middle and narrow on both sides is easy to occur at the foot of the wall or the wall is not too flat. Small cracks in these parts are not a big problem, you can use sandpaper to polish and polish, and then change putty powder or wall paint to repair.

The quality of the raw materials themselves is not up to par or the whole process of wall paint coating is destroyed due to weather conditions. For example, during the construction period of the project, baking, exposure, and strong wind blowing the wall; or the temperature is too low, so that the paint cannot produce a continuous coating. For example, the most widely used wall paint at this stage - wall paint, the paint on the wall paint is not suitable for too fast, some employees in order to better the construction period, in the case of the first layer of wall paint is not dry, immediately brush off a layer, so it is very likely that the painting work will be completed in three to five days, but the wall is easy to crack in the future.

First of all, it is necessary to see what causes the cracks, and there are many reasons for the occurrence of cracks, such as: building defects, insufficient concrete mix ratio in the case of mortar leveling, or the batch of putty is completed without drying the mixed mortar, which will lead to cracking after the mixed mortar is dried. There will be wall paint cracks after the interior decoration is completed, and another is that the decoration workers in the construction of the project in order to better reduce the construction time, the bottom of the batch does not wait for the bottom layer to dry thoroughly, on the grinding and polishing, this situation will also occur.

Painting requires the construction environment temperature not to be less than 5, the relative humidity is not higher than 85%, therefore, the rainy season, Huangmei day, the temperature is lower than 5 in winter, are not suitable, it is best to paint in sunny and dry weather.

Below 20 degrees, it will crack at this time. Therefore, the decoration needs to be above 20 degrees, and the weather needs to be good.

Generally speaking, if you decorate in summer and winter, the wall paint will be more prone to cracking; In fact, too cold and too hot are not suitable for wall paint, in the later stage it is easy to crack, it is best to be moderate, such as spring and autumn is very suitable.

Decoration should pay attention to the season, not when you want to decorate, because the season and temperature will have a certain impact on the decoration materials. So, can you paint the walls normally in the cold winter? Is decorative wall paint prone to cracking in winter?

If so, will the temperature be affected?

The first thing to tell you is that if the decoration temperature is too low in winter, it will affect the effect of wall paint, so it is not recommended to paint wall paint in winter. While some wall paint instructions indicate that the temperature can be brushed above 5, in fact, as long as the room temperature is below 10, the wall paint will crack. If you are really in a hurry and can only choose to decorate this winter, it is recommended that you pay attention to the following:

In order to facilitate construction, the manufacturer will produce wall paints suitable for different seasons. Therefore, when painting walls in winter, we should choose materials for this season. If you choose the wrong one, either the wall paint dries slowly, or it directly affects the quality of the decoration.

Before painting the wall, the first thing to do is to do a good job of the base treatment. In addition, when scraping putty, the moisture of the putty scraped for the first time is easily lost due to the relatively dry indoor air. Therefore, you can't wait until it's completely dry for the first time and it's not too late for the second time.

In addition, after buying wall paint, it should be placed in a place with high temperatures. Balconies, bay windows, and shaded rooms are cooler in temperature. Wall paint is easy to freeze here.

At the same time, it is best to paint the walls between 10 and 5 a.m., when the temperature is relatively high. The indoor temperature difference should not be too large, otherwise the wall paint will easily turn white after brushing. So, in general:

When painting in winter, it is necessary to pay attention to the indoor temperature, ensure the time interval, and ensure that the wall paint and putty are fully dry to reduce the hidden danger of cracking in the later stage. Note that the temperature is too low for construction. It is recommended to stop working.

Especially when the bottom putty is not completely dry, it is not suitable to carry out the next process. If you master these, there are still no problems with winter construction.

It is very easy to crack, because in the process of decoration, if the bottom is not polished well or the quality of the wall paint used is not good, it is particularly easy to crack, and the temperature is kept at 20 25 when it is not affected, if the temperature is too cold or too hot, there may be cracking.

Decoration wall paint is very easy to crack, if you do not choose a high-quality brand, or if you do not carry out proper maintenance, it will lead to wall cracking; Generally, it will not be affected if it is higher than 5.

Of course, it is easy, if it is lower than the tenth degree, it will lead to wall problems, so it will lose powder.

On rainy days, the temperature is low and the air humidity is high, so try to avoid transporting decoration materials and paints for painting on rainy days. Temperatures below 0 are not suitable for decoration. Generally, the ambient temperature during the construction of mixed color paint should not be lower than 0.

The ambient temperature when applying the paint should not be lower than 5, and the ambient temperature when applying the varnish should not be lower than 8. Therefore, the winter renovation project must ensure that the indoor temperature is at least above 5. In particular, the oil work should pay attention to "heat preservation", and then open the doors and windows for ventilation after it is fully dried.

The wall paint temperature is generally above 5 degrees can be brushed, but less than 5 degrees is not recommended for construction, and it is best to apply on sunny days.

The minimum film-forming temperature for cream is 0. The coating film is thin during painting, and it is easy to freeze and destroy the latex particles in a cold environment, and the temperature of the film-forming environment is low, and the film-forming is easy to be incomplete. Latex paint film formation is a relatively slow process, and it can be formed in 257 days.

Cold and rain should be avoided during film formation. In the process of applying cream in winter, the surface of the wall is sometimes cracked and peeled. This is the cold weather in winter, the wall, the surface of moisture, condensation, if not directly brush the wall paint, primer, the temperature will be high will appear small bubbles burst, the wall will be peeled, peeling off the phenomenon in the later stage of construction.

In winter, when decorating and painting paint, the indoor temperature is above 5 degrees. If the temperature is too low, even if the paint is too low, the paint will crack, affecting the effect of the paint. The winter construction environment is different from other seasons, and the wall surface may crack or peel off during the painting process.

This is because the winter is cold, there is moisture and condensation on the walls and surfaces, and if you don't treat it, you can directly apply wall paint and primer, and as soon as the temperature rises, small bubbles will form and burst, and the wall will sometimes peel off and fall off in the later stage of construction.

Therefore, the doors and windows are closed when painting in winter, which can not only maintain the indoor temperature, but also avoid the outdoor wind and sand blowing on the undried wall, causing rough and uneven phenomenon. Latex paint must be diluted with water in accordance with the manufacturer's instructions for use. Excessive dilution will reduce the hiding power of the coating film, make the color lighter, the coating film will become powdery and powdery, the performance will be reduced, and the gloss of the coating surface will be uneven.

After the latex paint is painted, the ventilation is too large when it is not dry, which produces strong convective wind and cracks on the surface of the latex paint. For old walls that have been in disrepair for a long time, the surface has serious paint peeling, and the plaster layer is silted, and the whole layer of paint and plastering needs to be removed until you see the cement plastering or brick layer. Then, before applying the primer, mix the double fly powder and rubber powder well and apply the cream.

The top coat needs to be applied 2 to 3 times, preferably 24 hours apart.

It is not easy to crack when decorating the wall paint in winter, as long as we decorate it well, and the temperature is more than 20 degrees Celsius.

Wall paint is particularly susceptible to cracking because the temperature in winter is very low. If the temperature is around 15 degrees Celsius, it will not be affected, but if it is lower than 10 degrees Celsius, it will crack.

Decoration wall paint in winter is very easy to dry and crack; Because the temperature in winter is relatively low, the walls are very dry, and the influence of air currents will cause paint to fall off and crack. In this case, it is necessary to maintain the temperature in the room, as far as possible not lower than 8.

Decoration pays attention to the season, and it is not necessary to decorate when you want, because the season and temperature will have a certain impact on the decoration materials. So, is it possible to paint the walls normally in the cold winter? Is it easy to crack when the wall paint is late in winter?

If so, how many degrees will the temperature not be affected?

The first thing to tell you is that if the decoration temperature is too low in winter, it will really affect the effect of the wall paint, so it is not too quiet to paint the wall paint in winter. Although some wall paint manuals indicate that the temperature is above 5, in fact, as long as the room temperature is lower than 10, the wall paint will crack after brushing.

1. In order to facilitate construction, the manufacturer will produce wall paint suitable for use in different seasons. So when painting the walls in winter, you should choose the materials of the season. If you choose the wrong one, either the wall paint will dry slowly, or it will directly affect the quality of decoration.

2. Before painting the wall paint, first of all, do a good job of grassroots treatment. In addition, when scraping putty, because the indoor air is relatively dry, the water in the first putty is easy to lose. Therefore, you can't shave it the first time, and you can't shave it a second time until it's completely dry.

3. After the wall paint is bought back and the luggage is transported indiscriminately, it should be placed in a place with a relatively high temperature, and the temperature of the balcony, bay window, and shady room is relatively low, and the wall paint is easy to be frozen here. At the same time, it is best to paint the walls between 10 and 5 a.m., when the temperature is relatively high.

4. The temperature difference in the room should not be too large, otherwise the wall paint will be easy to return to white.

So in general: in winter, we should pay attention to the indoor temperature, ensure the time interval, and ensure that the wall paint and putty are fully dry, so as to reduce the hidden danger of cracking in the later stage.

Although the cost of wall decoration in the paint accounts for only about 10, but accounts for 80% of the decoration area, then according towall painting cycleWhen should we move in? The choice of wall coating will affect the health of the home environment, and unqualified and environmentally friendly paints can volatilize harmful substances that are harmful to the human body, such as toluene and formaldehyde. For people who live indoors for a long time, it is not clearwall painting cyclewill cause harm.

If you are only renovating the wall or painting only a single wall, choose a wall paint like water paint, and the first coat will dry before a second coat of paint. After that, wait for the walls of the renovated house to dry, and then you can choose to live in it. When painting wall paint, it is best to use it with a primer, especially in southern cities where the rainy season is more.

Many interior walls are strongly alkaline in humid environments. Alkaline flowers are easy to produce, and then the paint film is destroyed. In this case, the primer can avoid contact with moisture.

Primers are used as sealing, isolating, moisture and mildew resistant to cover the base layer of the wall and increase adhesion to the wall.

The entire home renovation of a new home involves all aspects except the walls, as well as the purchase of custom cabinetry, wardrobes, furniture, and soft furnishings. Therefore, the source of indoor pollution for this decoration comes from various aspects, such as the finished lacquered panels. Furniture wallpaper, glue and other hardware accessories, such decoration is recommended for everyone to ventilate for more than 3 months after decoration.

There is moisture on the wall of the new house, and the wall paint is directly applied, and if it is not treated in time, it will produce wall peeling. wall painting cycleThe interval between the first wall paint and the second is recommended to be more than 12 hours, more than 24 hours is better, depending on the humidity of the air, to ensure that the first pass can be dried, and then the second brush, otherwise the first time is not dry, and the second brush is prone to problems such as peeling over time. Secondly, if there is moisture or condensation on the walls or surfacesThe walls are painted in the hail periodIt will become longer and will have to wait until it is dry before applying putty and paint.

If not treated, apply wall paint or primer directly. Once the temperature rises, it forms a small bubble that causes cracking.

Remember, if there is a shade, it means that there is moisture, not dry, wait until it cracks and then renovate the wall, this timewall painting cycleBut don't forget it.

Wall cracking, especially the irregular "cracking" phenomenon is the most common, the specific cause depends on the situation, and the base layer is not properly treated: such as the cracking of the coating film caused by the cracking of the wall; If the first coating is too thick and not completely dry, the second coating will be applied, which will cause cracking of the coating film due to the different drying speeds inside and outside; The construction temperature is too low, and the film-forming temperature of latex paint cannot be reached, and a continuous coating film cannot be formed; There is also the cracking of the cement putty scraped in batches, causing the cracking of the coating film, and the reason for the cracking may be that the construction putty is too thick or the interval is short, and the putty is not dry.

Before putty plastering, all the shells and cracks on the wall should be removed, and the filler should be used to level the wall, remove all the residual slurry, garbage, oil, concave and convex places and rough surfaces on the wall, and then clean the wall, and then clean the wall, and then carry out it after it is completely dry, and generally complete the leveling layer two to three times; After the putty is batched, it is completely dry, and then used a 280-360 mesh abrasive cloth to polish and smooth, and after dust removal, you can apply the wall sealing primer (generally one or two times) matching the purchased latex paint (topcoat), and then paint the topcoat; Both the primer and topcoat can be slightly thinner (with a maximum of 30% of the water added) to avoid brush marks; Each coat of paint must be allowed to dry thoroughly before being applied a second time; In addition, if there is paint construction at the same time, it should be done after the putty is approved, and then apply latex paint after the paint is completed (referring to the wood paint in the oily paint), so as to avoid unnecessary losses due to the volatile toluene of the paint to turn the emulsion paint yellow.

When using the roller to cooperate with the construction, you must first use a brush to paint the parts that the roller can not reach, and then use a large area of the roller to roll after 2 or 3 hours, and the roller should be selected with a high-quality roller; Construction should be avoided in rainy and foggy weather, generally under the temperature of 25, humidity of 50% construction is best; Note that it is not suitable for construction under the condition that the wall surface temperature is lower than 10, and the surface layer needs to be painted 2 to 3 times to achieve the fullness of the paint film.

It is particularly emphasized here that the paint should be stirred evenly before use, and the consistency of the paint liquid should be mastered, which is the key point that cannot be ignored; All in all, it is a meticulous manual work, and it is necessary to fully control any link related to the construction, so as to avoid or reduce the cracking phenomenon in the construction of wall coatings!
