Swift Seal Ultra is an impregnating seal that is breathable and non-darkening, with an invisible finish. It is long lasting, stain repellant, water and oil resistant, and alkaline cleaner resistant. Suitable for both indoor and outdoor use on stone, concrete and wood surfaces.
Wear gloves and goggles, and keep your work area well ventilated. For best results, ensure the surface is clean and dry before applying. Work on a 2-3 sq metre area at a time, to ensure it is all within reach. Apply Swift Seal Ultra generously to the surface, and work into the surface using a sponge applicator. Return to the start point, and without applying any more product, work the applicator over the area again to ensure no parts have been missed. Concentrate on areas that have already dried. After 2-3 minutes, if there is any visibly unabsorbed seal, spread this evenly over the whole surface for an even finish. If required, when the seal is completely dry, apply another seal using the same process.

This product can also be used as a pre-treatment before grouting, and will significantly decrease the darkening effect of other Stonetect products.
1L will cover approximately 4-12 sq metres.
