Extra-Prep® can be used to skim coat interior
and exterior walls and ceilings made of rough cementitious building
materials such as block, brick, poured or tilt-up concrete. Extra-Prep® is
excellent as a joint filler, too. This Ph tolerant, acrylic based,
ready-mix product fills cracks up to ¼" deep with very low
shrinkage and dries to an extremely hard finish. It's flexible and
compatible with most exterior finish systems.
Available in 5 gallon pails.
