SILRES® BS 1702 may be applied in undiluted form or diluted with organicsolvents. SILRES® BS 1702 serves as a high-quality specialty water repellent for impregnating fiber cement boards and panels and construction materials. It will provide good depth of penetrationand will greatly reduces water absorption. For very high quality concretes we recommend applying SILRES® BS 1702 either in undiluted form or in a concentration of no less than 1:4. For fiber cement of lower quality, it may be diluted down to 1:9 if necessary. Suitable solvents include aliphatic and aromatic hydrocarbons, particularly white spirits, and anhydrous alcohols, such as ethanol or 2-propanol.
