Exposed Aggregate Sealer 312

Exposed Aggregate Sealer 312 is a hardwearing solvent based clear sealer designed to enhance and protect exposed aggregate concrete, including high wear areas such as driveways and paths. It can be used to ‘soften’ aged exposed aggregate where the concrete is worn away exposing sharp angular stones.  The sealer fills smaller voids and coats sharp edges making the aggregate 'softer’ underfoot, which is desirable around patio and pool areas where bare feet come into contact with the surface. It dries to a high gloss ‘wet look’ clear finish and provides a smooth washable surface, protecting from stains, spills and reduces the ability of moulds, algae and lichen to discolour the surface. It's a UV stable solution acrylic with excellent optical clarity and is designed to provide many years of service.

Exposed Aggregate Sealer 312 is well suited to protecting new surfaces or restoring aged and faded exposed aggregate concrete.


For re-sealing over existing solvent-based sealers we recommend the addition of 10% Solvent 399 to the 1st coat to ensure the new sealer bonds correctly.


If you have a sloping driveway, you may need to add some anti-slip powder to your final coat... This will add texture to the coating and provide grip. Click here to view the anti-slip powder page for more information.

Coverage is approx. 5-7m² per litre - allow approx 1 x 5ltr pail per 15-17.5m² of concrete (2 coats) - dependent on surface
