Treated surfaces are more durable, easier to maintain and possess an increased ability to withstand moisture related problems. #JUSTSEALIT penetrates deep into a porous material, physically altering the surface tension. A permanent chemical bond is formed after 30 days resulting in a hardier and more durable surface.

Corrosion can occur on untreated natural stone, tile, concrete and grout by being exposed to various environmental elements. Damage can be caused by mould/mildew, efflorescence, salts in pool water or even just slightly acidic PH rain water.

Application of #JUSTSEALIT will reduce or eliminate the impacts of corrosion. Efflorescence presents as an unsightly white powdery salt haze, and can cause permanent damage to a porous material if not addressed. It is a common occurrence in both natural and man-made stone, but can be significantly reduced or even prevented by treating with #JUSTSEALIT sealants.

Our sealants can be used on all natural and man made stone, tile & concrete. They're suitable for most indoor and outdoor surfaces, with finishes including: Bluestone, Concrete, Sandstone, Limestone tiles/masonry blocks, Basalt, Brick, Tile, Granite, Slate, Grout, Travertine, Terracotta, Terrazzo, Clay, Porcelain (unglazed natural), Marble and more.

Ensure material to be treated is clean and bone dry.

We recommend cleaning with our Stone Wash neutral PH cleaner and Stain Aid for any
organic stains. Ensure leaves and debris are removed during autumn months to mitigate algae growth.

Application of sealant
Apply one wet on wet coat (two coats applied at once). Applicate sealer left to right then immediately apply sealant in opposite direction - with low pressure sprayer and / or lambswool applicator, ensure there is no excess or pooling evident.

The curing time is 28 days from initial application however once the sealant is visibly dry (usually 1-2 hours) light foot traffic is permitted.
After 24 hours furniture can be placed back onto the treated surface and allow 48 hours for vehicles. Pool water containing corrosive minerals and chemicals to be washed off immediately.

All surfaces absorb sealant differently, please refer to our application guide on our resources page, for coverage rates.

If you are still not sure how much to buy, please get in contact with our friendly staff.

Whilst the sealant will provide permanent protection, the efficacy over time may decrease at different speeds depending on the environment and usage. We recommend re-application between 3-5 years for optimal protection. 

Yes, our technology is designed and tested to withstand the harshest of environmental conditions.

Depending on the original sealant, our product can be applied over natural penetrating / impregnating sealants if the surface was thoroughly cleaned and prepped. If there was a physical acrylic / polyurethane coating or a wet-look sealant then this will need to be removed prior to application. Basically, if you can see a sealant, no, if you cannot, yes.

Water and solvent act merely as a carrier of active ingredients onto a substrate, both will evaporate after impregnation occurs. Traditionally solvents were considered to be better as they allowed better depth of penetration, however with a global shit toward sustainability the focus has shifted and water-based technology has evolved.
