Enviroseal is an effective water repellent liquid based on a solvent free silicone/siloxane emulsion for use above ground on porous brickwork, cement renderings, asbestos, cement/mineral boards, unglazed tiles, cast concrete, roughcast, stonework (including calcareous materials, i.e. those containing limestone), wood, canvas and leather.
Surfaces treated with Enviroseal remain permeable to vapour so that moisture within the structure does not remain trapped.
Enviroseal is clear and colourless and will not normally alter the appearance of treated surfaces. In some circumstances, however, very slight darkening may occur.
The treated masonry surface will not prevent the penetration of water at pressures greater than approx. 1.4kg cm² (20lbs per square inch).
Depending upon the nature of the surface to be treated and conditions of exposure, two coats of Enviroseal can be effective for at least 10 years.
Note: Enviroseal is NOT
a dustproofing sealer or a damp-proofing membrane.Application
Protect surfaces liable to be splashed during treatment, especially glass window panes, UPVC window frames and decorative coatings. Apply two coats of Enviroseal liberally to the prepared surface using a large brush, lambswool roller or low pressure pneumatic spray equipment.
Take care to ensure no excessive overspray occurs and avoid inhalation during application. In exceptional circumstances a further coat may be necessary.
Allow at least 2 hours between coats and do not apply to surfaces affected by rain or frost.
Coverage will depend upon the porosity of the surface to be treated. Typical consumption is 4-5m² per litre per coat, this may be reduced to 2m² per litre on highly
Any overspray should be removed with silicone cleaner. Treated surfaces may be overpainted with masonry paints after approximately 1 week..Coverage
Apply 4 - 5m² per litre, per coat, depending on porosity of substrate.Product Data Sheets
