Render & Masonry Sealer is a water based impregnating sealer suitable for sealing the exterior surfaces of a wide range of building materials. Render & Masonry Sealer can be used on porous render, concrete, natural stone, brick and general masonry. This render sealer is an impregnating sealer, so fully breathable. Render & Masonry Sealer is resistant to organic staining, rain water penetration, carbon contamination & UV light.
This protective sealer will last 10 years or more. This is due to its resistance to UV light, water penetration, organic growth and carbon deposits from pollution. Floorseal Render & Masonry Sealer can be applied to any porous material including general render, concrete, natural stone and general brickwork. Easy to apply using a low-pressure sprayer, roller or brush in two consecutive applications. Apply once generously and then lightly reapply approximately 40 minutes to one hour later – less product will be required during the 2nd application. If any sealer runs or pools redistribute this with a brush/roller, so all the product soaks in evenly. This water-based sealer fully penetrates the surface of the material being treated. Render & Masonry Sealer does not alter the appearance of the material being sealed and is 100% breathable. Render & Masonry Sealer is not a surface coating, it is a penetrating sealer which soaks into the pores of the surface, therefore seals from within.
Please note: This product is not over paintable – If you require an over paintable sealer we recommend Floorseal Stabilising Solution.
Available in 5 litre, 10 litre (x2 5 litre) & 20 litre containers with free economy shipping and express delivery shipping options. Samples are available from the select size option button.
