How do I know if the drywall was ever primed or sized and sanded? The wallpaper is peeling off in one piece, just like it went up.
I've been practicing on a scrap sheet with a light-weight mud and a large trowel. I'm thinking about:
--Troweling 2 or 3 lightweight coats, looking for a stucco or plaster like finish
--Troweling 1 or 2 lightweight coats and try for a knock-down like finish
--Troweling 1 or 2 lightweight coats and try to match what looks like an oval sponge off finish on the few walls in my house not wall-papered
--Troweling a light coat on and use a texturizing roller I got at my local lumbar company.
Your co-operation is appreciated.
The drywall will be white if it's been primed. If the paper came down that easily, it must have been sized. If nothing was used, the paper would be a lot harder to get off and the wall would be bare drywall (gray).
As far as sanding, it will help remove any leftover paste or other debri and smooth the surface.
To achieve a venetian plaster look, trowel on a couple of coats. I don't know what you mean by lightweight? you mean pre-mixed drywall mud?
For any of the other textures, you'll need to use the roller. For stucco, just apply the mud and roll it. Roll less for a rough texture, each time you roll over the mud the stucco texture will be less pronounced, but still stucco.
For a knockdown, apply the mud, roll it and then lightly drag your knife over the stucco to knock it down. This will require some thinning of the material.
Yup, I'm avoiding the direct question. I don't know what would look best for you. I like either the plaster look or match the sponge.
