UGL® Plaster-Patch®

UGL® Plaster-Patch®

UGL® Plaster-Patch® is the original, pure white, slow-setting, glue-based, patching plaster that can be troweled to a fine feather edge with minimal shrinkage on interior drywall, plaster and marble. Although this product is an economical option, its superior plasticity allows for smooth, even spreading without the annoying crumbling and rolling that often occurs with products of lesser quality. UGL® Plaster-Patch® is specially formulated for repairing large defects in plaster walls.

Remove any broken or loose plaster* around the area to be patched.* Dampen the entire area with clean water, including any plaster and wooden laths.


In a clean container, add 3.25 cups of UGL® Plaster-Patch® to 1 cup of clean water. Using a mixing paddle, stir thoroughly to form a stiff paste. Small amounts of UGL® Plaster-Patch® can be added to adjust the consistency to your liking. Stir slowly and for long enough to obtain the desired consistency. Prolonged mixing will speed up the set time. Before remixing a new batch of UGL® Plaster-Patch® in the same container, it is important that you clean out any leftover product that has set in that container. If any of the old mixture – which has set - is not removed from the container, a chemical reaction will take place and cause the new batch to set much faster.


Apply with a trowel or putty knife. Force the UGL® Plaster-Patch® into the area. Smooth out the patch with the surrounding surface and allow the patch to dry. After the area has completely dried, sand the patch smooth using fine sandpaper. For best results, spot-prime the area before painting. The setting time of the patch is approximately 1.5 hours. Clean your application tools immediately after use with warm, soapy water.

When smoothing wall surfaces or repairing fine cracks, small breaks and scratches in wood, wall board, plaster or masonry, use UGL® 222 Spackling Paste or UGL® 222 Lite Spackling Paste.


Dispose of contaminated absorbent, container and unused contents in accordance with local, state and federal regulations.
