What should I do if the furniture paint doesn t dry all the time?

Reasons: (1) the porosity of the substrate is not uniform, and the adsorption of the resin is different, (2) the thickness of the primer and topcoat construction is uneven, (3) the local dry spray is sprayed (4) the same wall uses different batch products, (6) the effective "wet joint", the scar is obvious, (7) the substrate humidity is too high or the paint dries too quickly.

Solution: 1) The use of primer, especially the local repair, must be the same as the surrounding primer before applying the topcoat (2) to ensure that the thickness of each layer is consistent, no missing brush (3) to ensure the use of consistent tools, the same batch of products on the same wall, to ensure wet connection in the distribution area (4) to ensure that the construction conditions and construction technology meet the requirements.

This is just a matter of waiting, and the effect is much better if the weather dries slowly.

Improper surface treatment. The residual oil, acid, minus, salt, etc. on the surface of the object are not completely removed, the pine resin, wax, and asphalt are not removed, and the primer is applied before it is completely dry, which will cause slow drying or local stickiness, and some even do not dry for a long time.

The paint is too thick, so that the oxidation only occurs on the surface, the solvent at the bottom layer cannot volatilize, and the paint film does not dry sufficiently.

Poor construction environment. The paint film is attacked by cold, rain, dew, smoke, acid, reduction or moisture; or paint in a humid and airtight room; or in the rainy season and foggy days, there is a large amount of moisture accumulated on the surface of the object; In addition, in the cold season, when painting slow-drying paint, there is no appropriate amount of drying agent added to the paint, or the moisture of the boudoir is too small when coating the large paint, etc., which is easy to cause the paint film to dry slowly or sticky.

Poor paint quality. The resin content in the paint formula is low, or the solvent with poor volatility or contains non-drying and semi-dry oils; The use of paint that has been stored for too long or the use of tung oil with too low refining temperature will also make the paint film dry slowly and sticky back.

Mixing different types of paints, or using too much of a drier, can cause the paint to dry very slowly (causing the surface conjunctiva to close and the inner layer to dry slowly) and even cause re-adhesion.

Hello, there are five reasons that you can refer to to see which step you have a problem with.

Question: What is the concept of curing agent bil in the wrong and impossible to not do more than 30 degrees of weather for more than a month.

The questions are all electrophoresis, and don't spray primer, or don't do it in batches.

Question: Therefore, it is necessary to ask clearly, if some do it and some do not, it must be a personal operation problem, and it must be a problem with the paint itself.

Wait a minute. It's said that some places do it, and some places don't dare, right?

It's not all done in large quantities, but some do it and some don't.

That's the problem of human operation, not the problem of paint.

Ask questions in large quantities and do not do it.

In that case, I recommend checking the paint first.

The question is to say that the fourteen barrels of paint I bought, sprayed twenty platforms, and none of them were useless and dry.

Furniture paint does not dry solution:

1) Wait for the water to dry completely before spraying;

2) Proportional reinforcement of chemical agent varnish;

3) Use the supporting diluent provided by the manufacturer;

4) Spray at normal room temperature;

5) Two or more constructions, prolong the construction time between layers, if the coating surface can not be dried, the coating should be shoveled off or washed off with a cloth dipped in acetone.

Another reminder, if it is a high-end furniture, buy a good furniture paint, Dabao paint is furniture paint should be said to be the best, don't buy some low-end.

Is there no curing agent added?
