- 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 955 is a ready-to-use product, no mixing required. However, after opening the container, the product must be thoroughly stirred until completely homogeneous before application. It is recommended to use a low speed mechanical stirrer.
➢ Application: MC-Proof 955 can be applied with brush, roller or airless spraying equipment. MC-Proof 955 should be applied with at least 2 coats crosswise and the waiting time for dry-touching of the coat is around 2-4 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 955 under rain or extreme weather. It 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 955 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.
