Product Description

Sikagard® 700 S Aquastop is a one part water resistant impregnation coating designed for absorbent cementitious substrates. Aquastop penetrates deep into the open pores of the substrate, offering durable water repellency, as well as allowing water vapour diffusion in both directions.

Best Uses

Sikagard®-700 S complies with the requirements of EN 1504-2 for hydrophobic Impregnation (penetration depth class I). As a product designed to offer excellent water resistance, Aquastop 700 S from Sikagard® is top of the range in an industry which requires highly protective coatings and efficient products. Best used on cementitious surfaces, the Aquastop can be used effectively on building façades, car parks, bridges, civil/engineering structures or excellently as a primer underneath Sikagard® 680S.

Sikagard® 700 S Aquastop can be applied using a brush, roller or low pressure spray and should only be applied in areas where there is good ventilation, due to the odour that it gives off. The surface should be clean, sound and free from laitance and losse friable particles. Dirt and contaminants, including grease, oil and waxes should especially be removed before you consider application.
