Wykamol No More Damp Enviroseal Water Repellent Usage Instructions

Substrates should be prepared by cleaning to remove all surface contaminants, including fungal/mould growths. Mould release agents or decorative paints should be removed completely. Structural defects, particularly mortar joints, repointing or rendering must be made good and allowed to cure for at least 1 month before treatment. Enviroseal will not prevent ingress of water through cracks or defective joints. If sandblasting / microblasting are carried out, ensure that the surface is hosed down with water extremely thoroughly. Repeat twice. Allow to dry. This is to ensure that the pores within the stone are not blocked with sand which may affect the application of Enviroseal.

Surfaces must be substantially dry before application of Enviroseal, and it is recommended that Treatment is carried out following a period of dry weather. Non-absorbent surfaces should be treated. Where backings are heavily contaminated with salts, there is an increased risk of spalling of surfaces treated with water repellents. The application of Enviroseal is not recommended under these circumstances. If doubt exists, advice should be sought from The Technical Department of The Wykamol Group.

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 4-5 m² per litre per coat, this may be reduced to 2 m² per litre on highly absorbent surfaces.
Any overspray should be removed with silicone cleaner. Treated surfaces may be overpainted with masonry paints after approximately 1 week.
