Mapei Mapeflex AC-P Acrylic Sealant With A Rough Finish 310ML

Mapeflex AC-P is a one-component sealant made from acrylic resins in water dispersion. It comes in the form of a thixotropic paste which is easy to apply in joints on both horizontal and vertical surfaces. After smoothing Mapeflex AC-P sealant, its surface has a “render effect” finish that helps it blend in with substrates with a rough or coarse textured finish.
• Seals made using Mapeflex AC-P remain stable even after years of exposure to all types of weather conditions, industrial surroundings and temperature variations. They remain flexible at temperatures as low as -30°C and are resistant to temperatures up to +80°C (up to +100°C for short periods).
• It has good resistance to accidental contact with diluted acids and alkalis. However, because of the wide range of products and service conditions that may be encountered, carry out preliminary tests beforehand.
• It also offers good resistance to water as long as it is not constantly immersed. Mapeflex AC-P complies with EN 15651-1 norm (“Sealants for façade elements”) with performance rating F-EXT-INT.
• Before painting over Mapeflex AC-P with elastomeric paints, the sealant must be fully polymerised. We recommend carrying out preliminary tests to make sure the sealant and paint are compatible.
Adhesion:
•  Mapeflex AC-P adheres well to all porous, absorbent surfaces such as concrete, wood, gypsum, render, brickwork, cellular cement, natural stone, etc.
•  It also adheres well if the surface is damp, but not wet, or if there is a film of non-stagnant water.
•  If joints sealed with Mapeflex AC-P are to be subjected to particularly severe service conditions, we recommend priming the walls of the joint (with Mapeflex AC-P diluted with water) just before applying the sealant.
