Stop water loss from porous pool plaster without emptying your pool. Cemcrete Pool Sealer is an advanced pour-in liquid designed to seal leaks caused by thin, worn or porous plaster from the inside out. Simply add it directly to the pool water and allow it to migrate into the pores of the plaster where it forms a durable, watertight barrier.
