The method for how to get rid of drywall texture depends on the material getting removed and the situation of the wall. The most frequent method for removing texture from painted drywall calls for sanding off the higher portions of the texture and filling it in with at least two thin layers of joint compound – named skim coating. A further method for unpainted textured walls and ceilings, such as popcorn ceilings, is spraying water on the surface to loosen the texture so you can scrape it off.
When a wall has comprehensive cracks, peeling paint or water harm, it may possibly be less difficult to cover the current wall with ¼-inch drywall or get rid of the current wall totally and replace it.
What ever method you use to get rid of a textured surface from drywall, defend your self from exposure to building dust, lead and asbestos.
Removing textured wall surfaces is an exacting method that requires patience. Here's how to tackle some frequent troubles so your walls will be smooth and your perform, lucrative.
How to get rid of drywall texture by skim coating
Issue: Uneven surface.
To keep away from developing an uneven wall when you happen to be removing the texture, never use a belt sander. It will dig up the texture. As an alternative, get rid of higher peaks in the texture applying a pole sander with 120 grit or a five-inch floor scraper.
Issue: Bulgy seeking patches.
Eliminate any loose material with a stiff brush, scrape higher regions and wipe with a damp cloth. To apply the 1st coat of joint compound, start off at the leading and perform across and down.
“The most crucial issue is not to use as well a great deal material,” says Ivan Solis, president of Chicago-primarily based Solis Building. “If you use as well a great deal joint compound, it will be tricky to realize a smooth surface. You are going to have to do a lot of sanding.”
Never be concerned about ripples, just attempt to cover the texture and get an even coat on the wall. Hold the joint knife at a 30-degree angle and press it in. “Preserve it tight and smooth,” says Solis, who recommends applying a 10- or 12-inch joint knife.
Alternate the path of the skimming strokes with every single new coat of mud. If you apply the 1st coat horizontally, apply the second coat vertically. Return excess mud from the surface to the rim of the pan, maintaining the blade of the knife clean.
When the 1st coat is dry, apply the second coat to fill in the ripples. Once more, start off at the leading in the corner and perform across and down. As you perform, knife off any significant chunks of the 1st coat, applying your blade. If there are nonetheless low and higher spots, you may possibly need to have a third coat. When the coat is dry, finish with a final sanding.
Issue: Joint compound that sets as well rapidly or is as well tough to sand.
Decide on the correct compound for the job. When a wall texture will need to have numerous coats of joint compound to smooth the surface, use a setting compound like Sheetrock Simple Sand for the 1st coat.
“Simple Sand 90 is a chemically setting compound that will give you about 90 minutes to perform just before it sets,” says Jeff Hartin, solution manager for USG's Prepared Mixed items. The solution is best for heavy fills and sands effortlessly.
“The good issue about a setting compound is that you can apply the 1st coat and start off a second coat as quickly as the 1st a single has hardened,” says Solis.
For the second or final coat, Hartin and Solis advocate a prepared-mixed joint compound, such as Sheetrock Plus three. The lightweight solution is less difficult to spread, permits a thinner application, and is less difficult to sand.
Issue: Stains leach by way of the joint compound.
These troubles are usually due to improper adhesion and are frequent on quite a few DIY painting projects. If the textured wall is peeling or plaster and textured joint compound are falling off, get rid of loose material with a scraper, sand and coat the surface with primer/sealer just before skim coating.
Issue: Cracks and dents reappear.
Repair cracks and dents just before skim coating. To repair them, tape more than the cracks with drywall tape and safe them with joint compound. When the wall is smooth, a drywall primer and sealer will seal the wall and assistance avoid cracks and dents from reappearing. Primer also neutralizes the pH of the wall for a far more even look.
Issue: Peeling paint and bubbling in the paint finish.
These troubles are usually due to improper adhesion. If the textured wall is peeling or plaster and textured joint compound are falling off, get rid of loose material with a scraper, sand and coat the surface with primer/sealer just before skim coating.
Pits on the surface of the drywall are air bubbles that had been not correctly filled or that had been exposed in the course of sanding. Air bubbles outcome from more than- or beneath-mixing the joint compound. Apply stress to the bubbles with the joint knife, till the pits are gone. If you never notice them till the wall is dry, cover them with joint compound and sand.
Issue: More than-sanding missing higher and low spots.
Sand as well a great deal and you threat damaging the surface paper. If that occurs, cover the location once more with joint compound. To keep away from missing higher and low spots, use a clamp-light or other light supply close to the wall to discover challenge regions. Sand methodically, operating from the ceiling to the floor in narrow sections.
How to get rid of a textured surface from drywall by scraping
Issue: Wall broken by water and scrapers.
Professionals advocate wetting wall textures with a spray bottle to loosen the material. Then use a scraper with a flat, wide blade to get rid of the texture. Use only sufficient water to loosen the material or you can harm the drywall. If you mark the sheetrock with the edge of your scraping blade, patch it with joint compound.
How to get rid of a textured surface from drywall by covering walls with drywall
Issue: Reinstalling trim.
“A single issue to preserve in thoughts when applying ¼-inch drywall more than an current wall is that not only will your baseboard, door and window casing appear a ¼-inch thinner but all of the “joints” will have to be filled with joint compound and caulked,” says Solis. You may possibly have to get rid of trim and reinstall it, and electrical outlets may possibly need to have extensions to bring them flush to the wall.
