Cemcrete Pool Sealer – Pour-In Liquid Pool Leak Sealer (No Draining Required)

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.

No draining. No mess. No downtime.

This is a fast, cost-effective solution for pools that are slowly losing water through ageing plaster surfaces.

How It Works

Cemcrete Pool Sealer is added directly into the pool water. The active sealing components travel through the water and penetrate the porous areas of the plaster. Once inside the pores, the product reacts and forms a watertight seal that helps stop water from escaping through the surface.
