Can you add water to exterior wall paint, can you add water to exterior wall paint?

Building exterior paints.

Adjust the whisker and dilute it with water. General latex paint.

It's all condensed. Method steps: 1. Remove the dust on the original wall. 2. If there is a peeling place, take putty and clean it. 3. Scrape putty where it needs to be repaired.

4. Sandpaper. 5. Mix brand latex paint with 10%-15% water. 6. Brush the wall Technical points:

1) If you originally brushed lime or paint, and now you want to paint latex paint, you must first remove the original wall and scrape putty again. (2), if you want to paint a colored room can directly buy colored latex paint, if you redeem yourself, must be redeemed at one time, otherwise there is color difference, of course, the gradual color difference is also a decorative effect. (3) The quality of the roller brush must be good, and the hair quality is moderate and dense, which affects the painting effect.

4) Brush the ceiling first, then the wall. (5), must be the first time to dry and then brush the next time (hehe, I have a lesson, or wet I will brush, bring the wall down the skin). 6) Uniform force.

7) Brush the light color 2 times, if you want a strong color, you need to brush it 3 times to be even.

Yes, don't add more, of course, it will become thinner, you can add water, exterior wall paint generally does not need to add water, interior wall paint generally needs, but it is limited to water-soluble paint. You can add water, try not to add water to the wall paint, it will dilute and it is not easy to paint Some exterior wall paints need to be watered, be sure to add an appropriate amount, stir evenly.

There are two types of exterior paints. One is water-soluble, and this paint can be diluted with water. The other is paint-based, which cannot be diluted with water.

According to the different design function requirements, higher requirements are also put forward for exterior wall coatings: for example, in the application of various exterior wall external thermal insulation system coatings, the exterior wall coatings are required to have good elastic elongation to better adapt to the surface layer cracking due to the deformation of the base layer.

It has a masking effect on the small cracks of the base layer; For the exterior wall coating of the anti-aluminum composite panel decorative effect, it should also have a better metal texture, ultra-long outdoor durability, etc.

Performance Requirements:

1. Good decoration: the exterior wall coating is required to be rich in color and excellent color retention, and can maintain the original decorative performance for a long time.

2. Good weather resistance: exterior wall coatings, because the coating is exposed to the atmosphere, must withstand the effects of wind, sun, salt spray corrosion, rain, cold and heat changes, etc., under the long-term repeated action of these external natural environments, the coating is prone to cracking, chalking, peeling, discoloration and other phenomena, so that the coating loses its original decorative protection function. Therefore, it is required that the coating of the exterior wall should not be damaged within the specified service life.

3. Good stain resistance: due to the large differences in environmental conditions in different regions of China, for some cities with developed heavy industry and mining, due to the large amount of dust and other suspended substances in the atmosphere, the easily stained coating will lose its original decorative effect, thereby affecting the appearance of the building.

Exterior wall paints generally do not need to be watered, and interior wall paints generally do, but only for water-soluble paints. Water can be added,

Some exterior wall paints need to be added with water, which must be appropriate and stirred evenly.

Try not to add water to the wall paint, it will dilute and it is not easy to paint.

Thank you for adopting.

Yes, don't add more, it will be thinned.

Be.

The proportion of paint to water is about 15%-20%. Do not exceed 20%. The proportion of primer to water is generally 20%.

Therefore, it is necessary to instruct the oiler not to overwater before construction. If it is brushed out, it may cause the effect of brushing, and it needs to be reworked, and the gains outweigh the losses.

For example, the usable area is 67 square meters, according to the calculation method, the total painting area is = 67 3 = 201 square meters, and the primer is brushed once, and 5 liters of primer can be brushed to about 80-100 square meters, then 2 barrels of primer are needed. The topcoat is generally brushed twice, and the simple algorithm is the number of primers 2 to get the number of topcoats. The usable area is 67 square meters, and the paint is painted, so the topcoat needs 4 barrels and the primer needs 2 barrels.

Precautions for exterior wall paint construction.

When carrying out the exterior wall paint spraying process, it is necessary to pay attention to the temperature and humidity of the construction environment, requiring the construction temperature to be 5 35, and the ambient humidity should be less than 75%, and avoid construction in rain, snow, fog and windy weather. Twelve hours before the rain, 24 hours after the rain should not be carried out construction, after the end of the construction within 8 hours should avoid rain or external damage.

The surface of the brush is coated with latex paint, generally diluted (or not diluted) with 5 10% water, fully stirred for construction, and a roller coating can be done. It is required to be evenly coated, not sagging, not leaking, and then the exterior wall surface is cleaned and maintained, and after completion, the wall should be rainproof and anti-fouling measures, so as not to damage the exterior wall coating for drying thoroughly, thereby affecting the decorative effect.

Summary. The primer is the first layer of the paint system, which is used to improve the adhesion of the topcoat, increase the fullness of the topcoat, provide alkali resistance, provide anti-corrosion function, etc., and at the same time can ensure the uniform absorption of the topcoat, so that the paint system can play its best effect. Topcoat can be without primer, this statement is not correct, because the function of topcoat and primer is different, topcoat is more focused on the final decoration and apparent effect, while primer focuses on improving adhesion, anti-corrosion function, alkali resistance, etc.

Primer refers to the paint that is applied directly to the surface of the object as a solid foundation for the topcoat. It is required to adhere firmly to the surface of the object to increase the adhesion of the upper coating and improve the decoration of the topcoat. According to the coating requirements, it can be divided into the first primer, the second primer, etc.

Hello, we are happy to answer for you façade primers that do not need to be added with water.

It is required to adhere firmly to the surface of the object to increase the adhesion of the car and the layer of coating, and improve the decoration of the topcoat. According to the coating requirements, it can be divided into the first primer, the second primer, etc.

Hello, dear, in general, water-based exterior wall paint is the same as interior wall paint in terms of environmental protection, so exterior wall paint can be used on interior walls, but it is best to use special interior wall paint for interior walls. Next, let's talk about the specific differences between water-based interior wall paint and exterior wall paint: 1. Water-based interior and exterior wall paint have their own special requirements, and water-based exterior wall paint is used to paint on the façade of the building, so one of the most important indicators of the collapsed limb is anti-ultraviolet radiation, which should not change color after long-term irradiation.

Interior wall paint, on the other hand, is used for interior wall flour brushing, and the requirements for UV resistance are much lower than those for exterior wall paint. 2. Water-based interior wall paint has high requirements for scrub resistance, and it is easy to stain the wall in home life, so it can be wiped with water at any time. 3. The exterior wall is required to have water resistance and self-cleaning.

The paint film should be hard and smooth, and the dirt will fall off as soon as it is washed. 4. The elasticity of interior and exterior wall paint is very important, and elasticity can prevent cracking caused by temperature and climate change. 5. Exterior wall paint can be used for interior wall painting because it also has water resistance, while interior wall paint does not have sun protection function, so it cannot be used to paint exterior walls, but experts suggest that it is better to use special use.
