How to remedy the cracking of furniture paint

In fact, it is not only furniture that has the problem of paint cracking, but also many things that have been painted in life have the hidden danger of paint cracking. Dry climate, furniture that has been used for too long, etc., can cause paint cracking.

Introducing three remedies for paint cracking:

Clear Oil Remediation Act.

For ordinary paint, add water to fine sandpaper of more than 800 meshes, carefully polish the cracks, clean the polishing place, and then brush the paint of the same color, and after drying, brush again; Water-based paint uses a special repair wax, which can be applied carefully.

Mixed Oil Remediation Act.

If the paint surface has been seriously cracked, the cracked paint surface needs to be carefully removed, coated with putty putty, sanded, and painted; If there is only a slight crack in the paint, it can be sanded directly and then painted.

Pay attention to maintenance during the construction stage.

Do not let the paint surface be too thick when painting, the thicker the paint surface, the more likely it is to cause the paint surface to crack due to the uneven heat and cold of the surface and the inner layer; Pay attention to waterproofing and do not place the paint surface close to the wool ground.

The main causes of furniture paint cracking:

1.Environmental causes: environmental factors, air, water, etc.; Direct sunlight, the paint film aging and decomposition.

2.Substrate reason: the substrate has not been cleaned of acidic or alkaline substances; The substrate is bleached, and the residual peroxide on the surface is easy to turn the paint yellow.

3.Product reason: use non-yellowing resistant paint; White lacquer is covered with ordinary varnish.

1. If the paint surface has been seriously cracked, the cracked paint surface needs to be carefully removed, coated with putty, sanded, and painted.

2. If there is only a slight crack in the paint surface, polish it directly, and then spray paint.

It depends on what kind of degree, if it is too serious, it has to be replaced, if it is mild:

Glue plugging. 2.Sandpaper is sanded flat and smooth.

3.Touch-ups.

If it is clear oil, then it can be divided into two types:

For ordinary paint, add water to fine sandpaper of more than 800 meshes, carefully polish the cracks, clean the polishing place, and then brush the paint of the same color, and after drying, brush again;

Water-based paint uses a special repair wax, which can be applied carefully. If it's a mixed oil:

That. 1. If the paint surface has been seriously cracked, the cracked paint surface needs to be carefully removed, coated with putty, sanded, and painted.

That. Second, if there is only a slight crack in the paint surface, polish it directly, and then spray paint.

Methods to prevent cracking of furniture during the construction phase:

1. When making the door, do not stick to the wool ground, and generally need to leave a certain distance.

2. When painting, be careful not to make the paint surface too thick, the thicker the paint surface, the easier it is to cause the paint surface to crack due to the uneven cold and heat between the surface and the inner layer.

3. After the carpentry work is done, it must be placed for a few days, and then painted after the moisture volatilizes, so as to prevent the paint cracking caused by the deformation of the furniture due to too much moisture in the wood.

4. When making the door cover of the bathroom, the back side should be treated with anti-corrosion and waterproofing.

Sand off the paint and then repaint.

You can only scrape the paint on the surface and redo it, or buy a tablecloth or something to cover it.

When repairing furniture after a crack in the paint, the remedies used vary depending on the paint finish. The paint of woodworking is divided into clear oil and mixed oil, of which the clear oil is divided into ordinary paint and water-based paint, and the treatment methods are different.

1. Clear oil. For ordinary paint, add water to fine sandpaper of more than 800 meshes, carefully polish the cracks, clean the polishing place, and then brush the paint of the same color, and after drying, brush again;

Water-based paint uses a special repair wax, which can be applied carefully.

2. Mixed oil. 1.If the paint surface has been seriously cracked, the cracked paint surface needs to be carefully removed, coated with putty putty, sanded, and painted;

2.If there is only a slight crack in the paint, it can be sanded directly and then painted.

Huage Furniture tells you that the paint of woodworking is divided into clear oil and mixed oil, of which the clear oil is divided into ordinary paint and water-based paint, and the treatment methods are different.

A.Clear oil. For ordinary paint, add water to fine sandpaper of more than 800 meshes, carefully polish the cracks, clean the polishing place, and then brush the paint of the same color, and after drying, brush again;

Water-based paint uses a special repair wax, which can be applied carefully.

B.Mix oil. 1.If the paint surface has been seriously cracked, the cracked paint surface needs to be carefully removed, coated with putty putty, sanded, and painted;

2.If there is only a slight crack in the paint, it can be sanded directly and then painted.

Construction Phase: Precaution.

To prevent furniture from cracking, it is necessary to pay attention from the construction stage.

1.After the carpentry work is done, it must be left for a few days to wait for the water to evaporate before painting. This prevents cracking of the paint surface caused by excessive moisture in the wood, which can cause deformation of the furniture.

2.When painting, be careful not to make the paint surface too thick, the thicker the paint surface, the more likely it is to cause the paint surface to crack due to the uneven heat and cold of the surface and the inner layer.

3.When making the door cover of the bathroom, the back should be treated with anti-corrosion and waterproofing.

4.When making the door, do not stick to the wool ground, generally need to leave a certain distance, so that after laying the floor, you can prevent the door from sticking to the ground and absorb the moisture from the ground.

Usual maintenance: Do not use moisture.

In addition to the need to pay attention to the production process, it is also necessary to pay attention to some common sense in the usual maintenance to minimize or avoid paint cracking.

1.Do not wipe the furniture directly with a cloth with water, as this can prevent the moisture from seeping into the furniture along the invisible fine lines of the paint surface, forming a paint hollow and eventually causing it to fall off. The correct way to clean should be to wipe with a clean, soft dry cloth or gauze.

When stained with corrosive chemicals such as stains or high concentrations of acids and alkalis, they should be washed off with mild soapy water and washed off with clean water. After drying, it is polished again with car oil wax.

2.The furniture in the bathroom is particularly prone to paint cracking or even falling off, so when using it at ordinary times, you must pay attention to the fact that if there is water vapor on the furniture, you should immediately wipe it dry with a dry rag to prevent the long-term erosion of water vapor.

The high temperature and dryness of the room in the northern winter caused the wood to shrink, but because the whole surface was fixed, the shrinkage force of the wood could not be released, and eventually cracked.

The easiest way to deal with this kind of cracking is to fill the cracks with the saw foam of the same kind of wood (very fine kind) with 502 glue, fill it flat, dry it and hand it over to the painter to polish the filling and surrounding areas, and finally find the color to completely cover the cracks and restore them to the original appearance of the furniture.

This simple treatment method is actually similar to dealing with cracks in white walls, where the putty fills the cracks, and the putty dries and then applies white paint again. However, whether it is a white wall or furniture, there will still be some traces after the cracks are treated.

1. Prevent paint cracking: prevent problems in the construction stage.

To prevent furniture from cracking, it is necessary to prevent problems from the construction stage. The reasons for the easy cracking of the paint surface in the construction stage are that the moisture content of the wood is too high, and the deformation of the wood after painting leads to the cracking of the paint film; The scraping putty is too thick, causing the primer to crack; The primer is thickly applied at one time, and when the thickness of the paint film exceeds a certain limit, the paint film performance will appear very brittle; If the paint is not matched according to the construction instructions, it is easy to crack.

Understand the reasons why it is easy to cause paint cracking in the later stage of construction, so it is necessary to pay attention to avoid these problems during construction. Before construction, the moisture content of the wood is finally tested to ensure that the moisture content is less than 15%, and then the construction is carried out; No matter what kind of putty, avoid one-time thick scraping; Avoid applying the primer thickly at one time and applying it thinly multiple times; Paint according to the construction instructions.

2. Prevent paint cracking: avoid water vapor during maintenance.

To prevent cracking of the paint surface, it is necessary to pay attention to prevent water vapor intrusion during maintenance. This is because the moisture will seep into the furniture along the invisible fine lines of the lacquer, forming a hollow paint surface and eventually causing it to fall off. In particular, the furniture in the bathroom is particularly prone to paint cracking or even falling off, so when using it at ordinary times, we must pay attention to the fact that if there is water vapor on the furniture, it should be wiped dry with a dry rag immediately to prevent long-term erosion of water vapor.

Cracks or even cracks occur in the paint surface of furniture, and depending on the paint surface, the remedies used are different.

The paint of woodworking is divided into clear oil and mixed oil, of which the clear oil is divided into ordinary paint and water-based paint, and the treatment methods are different.

If it is clear oil, then it can be divided into two types:

For ordinary paint, add water to fine sandpaper of more than 800 meshes, carefully polish the cracks, clean the polishing place, and then brush the paint of the same color, and after drying, brush again;

Water-based paint uses a special repair wax, which can be applied carefully. If it's a mixed oil:

That. 1. If the paint surface has been seriously cracked, the cracked paint surface needs to be carefully removed, coated with putty, sanded, and painted.

That. Second, if there is only a slight crack in the paint surface, polish it directly, and then spray paint.
