Pool Sealer 20L Underwater Leak Repair

CEMCRETE POOL SEALER — 20L Cemcrete Pool Sealer is a liquid sealer for repairing minor leaks in marbelite and plaster pools. The sealer is added to the pool water and works by being drawn into small cracks and pores in the plaster where it sets to form a waterproof seal. Can be applied with water in the pool — no need to drain. HOW IT WORKS Pour the sealer into the pool water with the pump running. The product circulates and is drawn into leak points by water pressure. Allow the pump to run for the recommended period. The sealer cures inside the cracks to stop the leak. SPECIFICATIONS Volume: 20L. For marbelite and cement plaster pools. Underwater application — no draining required. Manufactured by Cemcrete.
