Prymax is an easy to apply liquid polyurethane that forms a hard but flexible plastic seal on almost any porous surface.

Treat your rendered pond to a coat of armour; sealing out moisture and lime, consolidating fragile surfaces and leaving a tough, hardwearing glosscoat.

For a full pond coating system use 2 coats of Prymax clear and 2 coats of Prymax coloured.

A specially formulated all-in-one moisture cured polyurethane sealer for sealing concrete rendered ponds under the water line, Prymax Marine Clear Seal should be used above the waterline and for paving around the pond.

For damp proofing internal render, plaster, plasterboard and sealing dusty concrete floors, can be used externally on walls if overpainted to protect from UV. Can be used to coat internal woodwork.


One pack, ready for use.

Hard wearing, durable and long lasting.
