Instructions

1

Use a razor blade or putty knife to scrape away any large clumps of PL400 construction adhesive. Do not dig into or scrape the sheetrock under the adhesive.
2

Dampen a clean rag in mineral spirits, paint thinner or caulk and adhesive remover.
3

Rub the rag into the adhesive, until the entire area is coated in a generous layer of product.
4

Allow the product to work into the adhesive for the amount of time specified on the product. For paint thinners and mineral spirits, this is approximately 10 minutes; for caulk and adhesive removals, this is approximately 15 minutes.
5

Use a rag dampened with to attempt to wipe off the adhesive residue. If it removed, proceed to Step 4. If it does not wipe off, repeat Step 2 as many times as needed until the residue wipes away.
6

Fill a sink with water as hot as you can stand to touch and a squirt of liquid dish soap. Dip a clean rag in the soapy water.
7

Wipe down the surface with the soapy cloth to remove the adhesive.
