How to Use

CERESIT CP 43 WATERPROOFING COATING SUBSTRATE PREPARATION

The substrates must be level, solid, load-bearing, clean, dry or slightly damp and free of dust and substances which impair adhesion (e. g. release agents). At low temperatures, make sure that the substrate is free of ice. Edges must be chamfered. Chamfer all edges and cove inner corners using either CERESIT CN 83 Floor Repair Mortar or CERESIT CP 4

MIXING OF CERESIT CP 43 WATERPROOFING COATING

Mix the 2 components with a slow-running electric drill (approx. 400-600 rpm), preferably equipped with an anchor stirrer. First, briefly stir the liquid component. Then add the entire powder to the liquid component and mix until a homogeneous, lump-free compound has been produced (mixing time: at least 2 minutes). After the priming coat has dried, apply a uniform layer of CERESIT CP 43 using a trowel and a float.

APPLICATION OF CERESIT CP 43 WATERPROOFING COATING

Joints and penetrations: Movement and separation joints between buildings in the area in contact with soil must be expertly protected against ground moisture on the external side with CERESIT CP 50 Joint Sealing Tape. When applying the waterproofing coat on the substrate, any wall/pipe interfaces must be embedded by applying an approx.Water load type ground moisture: The waterproofing coat is applied in two layers, wet-on-wet, until the required wet layer thickness is reached.– Water proofing against pressing water: The waterproofing coat must form an all-round, "tub-like" layer so that the building is sealed against water on all exposed substrates. At least two layers are required.
