Render & Masonry Sealer can be used on any porous render, concrete, natural stone, brick and general masonry. This render sealer is an impregnating sealer, so fully breathable.

Versatile external sealer for all porous render and masonry surfaces

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.

Long life render sealer will resist the elements

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 overpaintable – 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. Please read the full instructions & related information contained within the Technical Data Sheet.
