We recommend sealing your natural stone with a penetrating/impregnating sealer to protect the stone and for ease of cleaning.  Please read this section in conjunction with our Installation Guide.


The paving/coping & grout should be completely clean and dry before sealing.  If Pool Coping is being installed around a salt water chlorinated pool, please read our Salt Water Pool section and Installation Guide for further advice.

A penetrating/impregnating sealer does not alter the colour of the stone. To intensify the colour of your stone, use an enhancing sealer. An enhancing sealer provides a 24/7 wet look to the stone. To see what your stone would look like when an enhancing sealer is used, simply wet a portion to compare. You are not required to purchase the sealer brand that we recommend (see below), however we do encourage you to purchase a penetrating sealer, ­not a sealer that only sits on top of the stone.

Please note, sealer should be applied in dry weather.  If applied in cold damp weather (and also winter months), the sealer could look patchy until it has had the time to completely dry out.

We recommend Dry Treat Stain-Proof Original™ Premium Impregnating Sealer.

For softer more porous stones (Limestone, Travertine) we recommend a combination of DryTreat 40SK, and DryTreat StainProof or Intensifia, particularly for use around pools with salt water or salt water chlorination.
