Roof Sealer

Roof Sealer allows full water vapour transmission so no trapped moisture or moisture clouding issues can occur.

Roof Sealer is designed to soak into the surface and any obvious excess is to be removed. Roof Sealer leaves the treated surface with a totally natural appearance. The sealer seals from within the pores of the tiles. It is not a film or ‘skin’ forming product so no sheen or shine.

As long as the roof tile is porous you can apply this sealer to it.

If the roof is new you do not need to pre-clean the tiles.

As a minimum we strongly recommend cleaning your roof with Floorseal Roof Cleaner Bio Wash prior to sealing. This product can be used at a later date to maintain your roof and further inhibit organic growth.

Some surfaces are more porous than others. Typically a coverage rate of 5m2 per litre for porous surfaces is achieved. But you may achieve 10m2 on dense surfaces like slate or some clay-based tiles.

This product can be sprayed on using a low pressure sprayer. Redistribute any sealer which is still visible on the surface after approximately 20-30 minutes.

On porous surfaces the sealer will simply sink in leaving no excess – follow up with a lighter application of product to ensure full protection.

Roof Sealer is a water-based impregnating sealer. It penetrates the surface of the tile, so is non-film forming. The polymers sit within the pores of the treated surface creating a water repelling barrier. Roof Sealer is 100% breathable.

Impregnating sealers do not form a skin/film/lacquer so cannot trap moisture. They do not alter colour or create a sheen so retain an unaltered natural appearance. Impregnators do not ever require stripping they can be reapplied, typically when the tile begins to display some porosity.

Acrylic-based sealers have the potential to trap moisture under the seal. Breathable sealers like Roof Sealer repel rain water, resist dirt, carbon deposits & inhibit organic growth without trapping moisture.

No, this sealer is an impregnating sealer, so not suitable for sealing cracks and holes. If the roof is leaking through physical damage caused by cracking or holes forming – this sealer is not suitable for making repairs.

Floorseal Roof Sealer is a non film or ‘skin’ forming waterproofer. It does not form a coating or layer (similar to a lacquer). It repels moisture which is soaking through the pores of the tiles then into the building.
