CERESIT® CO 81 is used for sealing existing brickwork against capillary rise of moisture. Seals capillaries and fine cracks of up. The silicification fluid can be injected with or without pressure. Experience has shown that the greatest effect is achieved with pressure injection. Durable sealing against capillary water absorption, even with later formation of secondary capillaries. Also suitable on damp brickwork.Available pack size: 10l, 30kg

Before applying CERESIT CO 81, make sure the substrates are level, solid, load-bearing, clean, gypsum-free and free of substances which may impair adhesion. The surfaces to be sealed must be crack-free.
CO 81 is either brushed or sprayed on. In the case of onlyslightly absorbent substrates, dilute CO 81 with water at aratio of 1 : 1. Immediately after the CO 81 coat was soakedup by the substrate, apply a slurry layer wet-on-wet. After theCR 65 layer is sufficiently hard, further slurry layers can beapplied. If CP 43, CP 44, CP 45 or BT 21 are to be used forsurface sealing, apply these products onto the second slurrylayer, after application of a priming coat (varies dependingon the product).
On dry or slightly damp substrates CERESIT CO 81 is brushed or sprayed on as a priming coat for CP 43, CP 44 and CP 45. After approx. 30 minutes, the respective CERESIT product is applied onto the slightly damp surface.
