How to remove the old paint layer from the surface of the paint

There are three ways to strip paint:

1. Use 240 or 320 sandpaper to sand.

2. Buy paint thinner, dip it with a rag and apply it on the façade.

3. Buy paint remover, spray it on the surface of the door and apply it with a rag.

It is not easy to completely remove the white paint, because the white paint has completely penetrated into the brown eye of the wood. If this is not successful, the color change can only be sprayed with an oil-mixed primer and topcoat, not a clear paint.

Of course, if the brown eye of the substrate itself is relatively small, or if a transparent primer is added to the bottom of the paint when making paint in the past, you can remove the paint first, and then use sandpaper to polish it, which is still very promising to completely remove the paint successfully.

Tools Raw materials.

Scrapers, wire brushes, coarse, medium and fine sandpaper, chemical paint removers.

Method: Inspect the surface for cracking, peeling, flaking and loose paint film. Depending on the severity of the damage, you may choose to use one or more of the following methods for surface treatment before applying a new coating.

Scrape. Whether it's plaster and wall panels or wood and ferrous metals, this is the traditional and effective method for most flat finishes. Triangular or oval blades are suitable for scraping corners and circular contours.

Be careful not to chisel or damage the surface. Sand all the burrs with medium garnet sandpaper first, then again with fine sandpaper.

Clean with a wire brush.

With a hard wire brush, care must be taken not to damage the substrate. Once all loose paint has been removed, sand the surface with medium garnet sandpaper and then fine sandpaper.

Burnish. If the paint film is only slightly peeling, you can simply sand it in the order of coarse, medium and fine sandpaper.

Chemical paint strippers.

Choose a paint stripper that is suitable for coating and substrate treatment. Since paint strippers are likely to damage brushes, use an old or cheap natural bristle paint brush to apply paint stripper. According to the manufacturer's recommendations, give the paint stripper sufficient reaction time, usually 15-20 minutes or more, depending on the thickness of the old paint film.

Carefully remove the softened paint film with a spatula or wooden scraper and scrape it into the double glove bag of the carton. If needed, apply another layer of paint remover, then wipe the surface clean with a paper towel, newspaper or special scrubbing pad. Remove children and pets from the work area before using these products.

Cover floors and steps, and remove plants, carpets, and furniture. When finished, dispose of the waste carefully following the manufacturer's instructions. There are some low-odor alternatives to strong solvent paint strippers, but they can take hours to do the same job.

Once the paint remover has taken effect, the surface is thoroughly sanded with garnet fine sandpaper and dust removed before applying the primer, colorant or varnish.
