Self Leveling Compound for 2 to 10 mm leveling for indoor purposes
Ceresit CN 69 is a Self-levelling compound suitable for concrete, cement-sand screed and other mineral bases to create smooth surface ready to receive textile, PVC, Linoleum and rubber coverings as well as ceramic tiles. Also, suitable for heated floors. Ceresit CN 69 is recommended only for dry indoor areas.
- Smooth surface, self leveling
- Resistant to concentrated loads
- Excellent crack resistant
- Smooth surface, self leveling
Ceresit CN 69 is a Self-levelling compound suitable for concrete, cement-sand screed and other mineral bases to create smooth surface ready to receive:
- Rubber coverings
- Ceramic tiles
Step by Step
Ceresit CN 69 adheres to all solid, load-bearing, clean and dry concrete surfaces free of substances which can cause separation. Wax coatings, oil, grease and adhesive stains must be removed completely. Concrete floors and cement screeds: Loose and soft layers of the subfloor should be removed mechanically. Clean the surface and remove the dust.
Prime the substrate with Ceresit R 777 Primer. On screeds dilute Ceresit R 777 1:1 with water, on concrete floors use Ceresit R 777 undiluted. Apply evenly with a lambskin roller. Do not allow the primer to form puddles. A second coat may be necessary on porous, highly absorbent substrates after drying. Apply Ceresit CN 69 when the primed surface is dry (approx. after 1 to 4 hours depending on the climate conditions). Nonabsorbent substrates (e.g. old tile coverings): Clean nonabsorbent substrates such as old tile coverings or floors with adhesive residues mechanically. Apply R 766 with a lambs wool roller onto the cleaned substrate with not more than 0.100kg/m² R 766 diluted 1:1 with water. The ingress of moisture into the floor structure must always be prevented by suitable measures (e.g. waterproofing membranes, barrier primers). This applies in particular to composite structures and concrete floors
Pour 5.5-6.0 liters of clean water into a mixing bucket and slowly add full bag (23kg) Ceresit CN 69, to get a lump free, homogeneous mix. Use appropriate mechanical stirrer ( with suitable mixing paddle) at approx. 600 rpm for 3minutes. Apply the levelling compound to the prepared, primed floor with either a flooring rake or smoothing trowel to the desired layer thickness. Once the material is evenly spread, roll the surface with an appropriate spike roller to eliminate the entrapped air. Protect the finished surface layer against too rapid drying (direct sunlight etc.). The mixed quantity of Ceresit CN69 must be be used within application time of approx. 20–25 minutes @ 23°C.
