Can waterproofing materials be applied in winter?

The waterproof material can be constructed in winter, and there are requirements for room temperature during winter construction, and it can be constructed when the room temperature is above 5 degrees, and it is not suitable for construction when it is lower than 5 degrees.

Precautions for winter construction of waterproof materials:

1. Base surface treatment

1. The base surface should be clean and free of cement slurry, oil and other sundries, and the concrete base surface should be cleaned so that the waterproof coating can be closely bonded, which is conducive to the penetration of the coating and the formation of crystals, and exerts the effect of secondary impermeability.

2. Check whether there are structural defects, the honeycomb, holes, cracks and the periphery of the upper and lower water pipes on the base surface should be filled and smoothed with the slurry blended with plugging materials, and the sharp edges and protrusions should be removed.

3. Before construction, thoroughly wet the working surface with clean water to form internal saturation, which is conducive to cement-based penetration crystalline waterproof coating.

With the help of moisture, it penetrates into the interior of the concrete structure. But keep the base surface of the five clear water.

Winter construction should be done for a wet section.

2. Partial primer

1. First carry out local painting in the order from top to bottom and from left to right.

2. It is necessary to ensure that the coating thickness is the recommended amount for construction, otherwise the slurry is too thin or unevenly stirred, and it is easy to powder or shell.

3. An electric mixer can be used to fully stir until a homogeneous slurry without powder is formed, and then stir again after standing for 10 minutes to make the slurry fully matured. The stirrer should be placed at the bottom of the container during the second stirring, and the lifting movement should not be done to avoid the slurry being wrapped in air, and the adjusted slurry should be used up as soon as possible.

3. Large-scale construction

1. Use a brown brush or scraper to evenly apply the slurry to the base surface that is fully moistened but has no open water, and pay attention to avoid missing brushes. When the previous coating has been cured and has developed sufficient strength, the next layer is applied, and each layer should be applied vertically to each other.

2. It is recommended to use glass fiber mesh cloth for reinforcement treatment at the interface of the upper and lower water pipes of the large gaps and easily deformed cracks, and the high-pressure spraying method can also be used for construction.

3. When the coating is solidified to the point that it will not be damaged by spraying water, it should be sprayed with water 1 3 times a day in winter (not freezing), or covered with damp and breathable burlap and straw mat for two days. The maintenance work lasts 1 to 2 days.

Yes, as long as the temperature is +5 degrees Celsius or higher, it can be constructed.

Yes, the general national standard waterproof material is resistant to low temperatures above minus 20 degrees.

Above 5 degrees is OK.

However, Qinglong has an environmentally friendly waterproof coating.

You can heat the water and stir it evenly to start construction.

Construction is also possible in winter.

It mainly depends on what waterproof paint you use.

Do not do waterproofing. When the base surface temperature is less than 5, freezing, frosting, and snow, construction is strictly prohibited.

Waterproof products have undergone strict low-temperature performance testing, as long as attention is paid to preservation, the quality will not be affected. It's just that the indoor temperature is not high at this time, resulting in waterproof coatings.

It will dry more slowly, but it does not affect the use of waterproof coating.

Once the temperature is lower than 5°, the waterproof coating will be frozen due to low temperature, resulting in the emulsion in the material breaking and the waterproof performance fails. Moreover, when the temperature is low, the waterproof coating will not be opened, and it will not dry after painting.

If it is not good to do waterproofing at low temperatures, but it can be done under special circumstances, such as some materials are indoors, and the temperature can be done, more information, better suggestions, free concrete waterproofing and leakage water repair technical consultation, to avoid the trouble of repairing today, leaking tomorrow, repairing every year, and leaking every year.

It is not easy to do it in the cold winter in the north.

<> regardless of the season of construction, the choice of waterproofing material depends on its quality. It is recommended to buy waterproof quality products, my own decoration of the Meichaofang water solid, waterproof and impermeable performance is very good, and the bonding performance with the base layer and roller coating, brush coating construction performance are very good. On the other hand, the waterproof material is of good quality, which can ensure that the occupants do not have the trouble of leakage and repair for a long time.

Of course, the purchase of waterproof materials should also pay attention to their environmental performance, and creating a green and healthy home is responsible for their own lives. Meichaofang Water Solid has passed the UL Green Guard [Gold] certification in the United States, Eurofins IAC [Gold] certification in Europe, GEV [EC1Plus] certification in Germany and [A+] standard certification in France, and is a truly excellent waterproof material.

Winter construction is not better than summer, and there are some details that need to be paid attention to in terms of waterproofing, such as:

1.Before waterproof construction, the condition of the base should be checked to ensure that the base layer is firm and stable, and there is no hollowing and cracking;

2.Before waterproof painting, the construction surface brush water needs to be pre-wetted, but there can be no open water;

3.When storing, the waterproof product should not be lower than 5 or more.

Kiss, <>

We're glad to answer your questions! Winter roof waterproofing can be constructed Winter roof can still be waterproofed, winter roof waterproof protection measures: 1. Regarding new projects that have heating needs, but cannot ensure normal heating, new projects under construction across the year, and suspended construction and delayed construction projects, etc., should be prepared before winter.

2. The thermal insulation protection of wintering projects should be adapted to local conditions, and the thickness of the insulation layer should be determined by thermal accounting. 3. Before formulating the wintering protection measures, the relevant engineering geology, hydrology, local temperature, frost heave characteristics and large freezing depth on the foundation should be carefully checked and checked. 4. Drainage should be done around the construction site and buildings, and the foundation and foundation should not be soaked in water.

5. For projects built on mountainous slopes, interception ditches and drainage ditches should be set up according to the direction of surface water activities before winter, but dark ditches and blind ditches should not be set up at the bottom of the building. 6. After the completion of the house planned according to the heating demand, it should be heated in time, and the indoor temperature shall not be lower than 5. When the above needs cannot be satisfied, overwintering protection measures should be obtained.

Expand the material: You have to look at the winter in the north or the winter in the south. For example, the construction temperature of polymer TPO waterproofing membrane is -5 degrees, which is rarely reached in southern coastal areas, and it can be done all year round for these places. The north is different, some places in the north are more than -5 degrees in autumn, it is not that construction cannot be done at this time, but the construction materials, construction time period, and construction methods are more targeted and selective.

Hope mine can help you! <>

Kiss! Hello, happy to answer your <>

Pro-winter roof waterproofing can be constructed, oh winter can also do roof waterproofing, but when doing waterproofing, you also need to do some protective measures. If you choose a waterproof material that is anti-freeze, you don't have to worry about the low temperature and can operate normally.

However, if you choose an ordinary one without anti-freeze protection, it is likely that waterproofing will be affected, as long as you choose the right one, it can still bring waterproofing effect. However, if the temperature is relatively low, such as the surface temperature has fallen below 5, or it is snowing or frosting, it is not recommended to apply in this case. Wait until the temperature has risen and the frost has melted before construction.

Because if the temperature is relatively low, some waterproof coatings will have the problem of freezing, and the waterproof performance will be greatly reduced. Hope mine can help you <>

Do you have any other questions?

<>1. If it is a two-component product, the ingredients should be proportioned according to the proportion of liquid, powder and water marked on the product packaging, and the viscosity of the coating should be adjusted to meet the construction requirements of different parts of the inside and plane. Generally, an electric stirrer can be used for stirring, fully stirring for 3 5 minutes until a homogeneous slurry is formed, and then stirring for 2 minutes after standing for 10 minutes to make the slurry fully matured; Note: The stirrer should be placed at the bottom of the container during the second stirring, and the lifting movement should not be done to avoid wrapping the material in the air, and the adjusted slurry should be used up within 1 hour.

2. Use a brown brush or scraper to evenly apply the slurry to the base surface that is fully moistened but has no clear water, and pay attention to avoid missing the brush. When the previous coating has cured and produced sufficient strength, the next layer is applied, and each layer should be applied vertically to each other. (Total thickness; 3. The interface of the upper and lower water pipes in the large gaps and the cracks that are easy to deform is reinforced with glass fiber mesh cloth; 4. High-pressure spraying can also be used for large-area construction; 5. After the coating film waterproof layer is completed and the experience is qualified, the protection and isolation construction should be carried out according to the design requirements.

Construction precautions: 1. Clean up the base layer during construction and keep the base level flat, clean and free of dirt; 2. It must be constructed on a wet base surface, but there can be no open water; 3. 24 hours after the end of construction, sprinkling and curing should be carried out for 2-3 days; 4. The waterproof coating packaging should be used up in a short time after opening, and should not be stored for a long time; 5. The surface construction can no longer be iced or frosted, and it should not be used when the ambient temperature is lower than 4 within 48 hours. When construction is necessary due to the construction period, the construction time can be arranged at 10:0 in sunny and good weather

Between 0-15:00, warm water (or hot water) can also be used to mix to speed up the initial setting time and increase the early effect. When the continuous ambient temperature is lower than minus 4, it is recommended to suspend the construction; 6. It is not suitable for construction in rainy and snowy days, and the surface of the new construction should not be exposed to rain before curing.

Within 48 hours after construction, long-term low temperature below rain and frost should still be avoided; In situations where air circulation is poor or not available (e.g. in enclosed mines or tunnels), fans or blowers can be used to assist in ventilation.

<> winter, waterproof construction can be carried out when the construction temperature is not lower than 5 degrees. In addition, the coating products of large brands have generally undergone strict low-temperature performance testing, and as long as there is no freezing damage during transportation and storage, the quality will not be affected. It is necessary to do a good job in the storage and storage of waterproof materials.

Place the product in a warm and dry place, and there shall be no water accumulation and leakage in the warehouse. Particularly cold areas such as warehouses and basements can be properly heated and insulated, and sponges, blankets and other areas can also be used to cover or isolate the products. Reduce the amount of moisture when applying waterproof.

1. The construction temperature should be at 5-35

For waterproofing, as long as the construction temperature is not lower than 5, and certain insulation measures are taken, there is no problem in construction. It is recommended to stop waterproof construction in winter, and stop waterproof construction when the construction environment temperature is lower than 5. Indoor construction pay attention to close the doors and windows, and if possible, you can turn on the air conditioning, heating, etc. to heat the construction site, so that the temperature of the construction site can meet the requirements, which is conducive to the drying of the waterproof coating film.

The construction time should be arranged between 10:00 and 15:00, which is also the time of the day when the temperature is higher, which is conducive to the dry and solid film formation of the waterproof layer.

2. Winter plugging products can be mixed with warm water.

The coagulation time of the plugging product in winter is slightly slower than in summer, and the use of warm water to mix the material can significantly increase the coagulation rate.

3. Reduce the amount of wet water on the base surface in winter.

In summer, the base surface is too dry, and the water evaporation is relatively large, so proper moisture is required when applying waterproof coatings. However, the temperature in winter is too low, and the evaporation of many substrates is not large, so the amount of wet water should be reduced compared with summer, otherwise it will affect the product performance and drying time.

4. The waterproof construction in winter should be brushed thinly.

Winter waterproof construction should be thinly brushed, and the "ten" cross method should be used for construction. Apply from top to bottom, from left to right, to ensure that the thickness of the coating is consistent with the instructions for use of the product. The purpose of applying thin brushes in winter is to prevent the paint layer from being too thick and the moisture drying unevenly leading to cracking of the paint layer.

5. Precautions for storage of waterproof products.

1) Place the product in a warm, ventilated and dry place, and there shall be no water accumulation and leakage in the warehouse.

2) Particularly cold areas such as warehouses, basements and other areas can be properly heated and insulated, and other areas can be covered with sponges, blankets and other materials to cover and insulate the products.
