MapePUR Universal Foam M offers local constructors an easy and simple solution for filling gaps, soundproofing and thermal insulation.

Buildings consist of various parts and structures which are made from numerous different materials, and it is inevitable that gaps occur or are formed when these parts are put together.

Mapei South Africa now offers MapePUR Universal Foam M for general gap filling, soundproofing and thermal insulation. It is a practical, convenient solution fit for the local construction industry as well as the DIY market.

This one-component expanding polyurethane foam is made from a mixture of polyurethane prepolymer, foaming agents and special additives, and does not contain any ozone layer damaging CFCs. A technically advanced but user-friendly chemical building solution, it is developed by the international Mapei Group, a world leader in the production of adhesives, sealants and chemical products for building.

Easy to work with
MapePUR Universal Foam M is available in a handy 750ml spray can with a trigger-operated nozzle that delivers up to 45 litres of polyurethane foam in free expansion. The foam hardens quickly and, subject to the prevailing temperature conditions, can be sanded after 30 minutes, or cut, ground, drilled or skimmed with cementitious products, or painted.

Expanding properties
The foam expands when it comes into contact with humidity and to increase the expanded foam volume, the substrates around the gap are dampened by spraying with water prior to applying MapePUR M. Similarly, to increase polymerisation in the foam and achieve a higher expansion level after injection into a gap, the foam can be sprayed with water.  

Apply anywhere
MapePUR M adheres well to all materials normally used in the building industry, such as brickwork, concrete, gypsum, wood, metal, glass, foam polystyrene and PVC. The hardened foam has excellent mechanical properties, high insulating and soundproofing properties, as well as good resistance to the formation of mould and mildew.  

Typical applications for MapePUR are:
•    Insulating and soundproofing door frames, window frames and roller blind housings.
•    Fixing support frames in place for door and window fittings.
•    Insulating through pipes for heating, air-conditioning and cooling systems.
•    Fitting and insulating construction features and fittings on roofs.
•    Sealing formwork to make it leak-proof when pouring in concrete.

“MapePUR M is such a convenient to use, versatile product that it is destined to be a standard item in every builder’s toolkit,” comments Mapei South Africa’s product manager, Paul Nieuwoudt.
