CERESIT® CP 43 is a fiber-reinforced bitumen waterproofing coat for the full-substrate waterproofing of structural components. It is suitable for all water load types, quickly rainproof and rapidly dries to produce a flexible, crack-bridging waterproofing layer. CP 43 can also be used for waterproofing containers and for fixing insulation, drainage and protection boards. It can be applied on all mineral substrates, e. g. brickwork, plasters, screed, concrete and on existing bituminous substrates. Available pack size: 28 kg
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
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.
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.
CERESIT CP 43 waterproofing coat is suitable for all water load types, quickly rainproof and rapidly dries to produce a flexible, crack-bridging waterproofing layer. CP 43 can also be used for waterproofing containers and for fixing insulation, drainage and protection boards. CP 43 can be used for these types of applications: joints and penetrations, water load ground moisture, waterproofing against pressing water.
CERESIT CP 43 waterproofing coat can be applied on all mineral substrates, e. g. brickwork, plasters, screed, concrete and on existing bituminous substrates. It would be recommended to use CP 41 bitumen thick-coating primer for priming the substrate before application of CP 4
Water (e. g. from the cellar base or from storey ceilings) must be prevented from running behind the waterproofing layer. Furthermore, the waterproofing coat must not be exposed to water running from unconnected downpipes. Always carry out the through-drying test on the building itself. The extent of drying can be checked damage-free in the excavation by taking a reference sample (e.g. a coated brick). Before back-filling, protect the waterproofing coat by fixing suitable insulation or drainage boards. Only use sand resp. fine-grained gravelly sand or a similar material. Back-filling and compacting must be done in alternating layers of 30 cm to avoid slippage of the protective layer.
