How can I remove liquidnails from a wall without trashing the wall to much?

Answer 1

It can be removed from certain surfaces. (See link)

Answer 2

First, carefully try to remove any large clumps with a sharp razor blade or putty knife, being careful not to damage the sheetrock surface.

Next, try using paint thinner (mineral spirits) or a caulk and adhesive remover such as Liquid Nails LN595 or similar product. Wear gloves since this will be a tedious and messy process and be sure to provide ample ventilation.

Using clean white rags, apply generous amounts of solvent to the area and let it soften the adhesive. After a few applications, you should be able to wipe most of it away, although a residual stain or thin layer may persist. Clean up with warm soapy water.

Prior to painting, you may need to repatch the ceiling with a thin layer of sheetrock mud...and sand to a smooth finish (assuming your ceiling is smooth). Then, apply a good primer and paint as you normally would. Let us know how it turns out.

Answer 3

If it is not fullly hardened or to thick, try a solven like paint thinner and apply it to the goo and let it set a bit to soften it up. Then use a putty knife and try to scrape it off. Then apply a bit more solvent to wipe up the residue.

Answer 4

Probably the best thing to do is to sand it off with an electric sander, otherwise you would have to scrape it off and that would gouge the wall.
