  • APPLICATION NOTES:

Substrate preparation:
– The substrate must be structurally sound and free from cement laitance, loose particles, dust, oil, grease and any other contaminants or old coatings which may affect the adhesion.
– Grind smooth all high spots and sharp protrusions.
– Surface defects such as voids, blowholes and static cracks must be repaired and refilled to prepare a sound surface for bonding.
– Horizontal substrates must have sufficient slope gradient to avoid water ponding.
– Metal surfaces must be rust-free and clean.

Mixing: MC-Proof DF 8 is ready-to-use dispersion. Mix thoroughly with a low-speed mechanical mixer prior to application for homogenization.

Application:
MC-Proof DF 8 can be applied with brush, roller or airless spraying equipment.
– For absorbent mineral substrates, primer can be applied by mixing MC-Proof DF 8 with 10% clean water at a usage rate of 0.2 – 0.3 kg/m².
MC-Proof DF 8 should be applied with at least 2 coats crosswise. The waiting time for dry-touching of the coat is between 1 and 2 hours, depending on the ambient conditions and the thickness of the coat.
– At extreme areas such as corners, wall and floor conjunctions, or build-up systems, MC-Fast Tape or an appropriate glass fiber mesh should be immediately embedded into the first fresh coat.

Precautious:
– Don’t apply MC-Proof DF 8 under rain or extreme weather.
MC-Proof DF 8 should not be used in permanent contact with water. Roofing structures need to be designed at least 2% slope gradient.
– Ambient conditions and surface temperature must be under 35°C during the application.

Protection and curing: Full cure of MC-Proof DF 8 waterproofing system is approximate 14 days after the final coat. However, water tightness tests may be carried out after 7 days. The freshly applied membranes must be protected from rain for a minimum of 6-12 hours.

Safety instruction: Please take notice of the safety information and advice given on the packaging labels and safety data sheets.
