Product benefits

  • High tensile and elongation strength
  • Resistant to aging and UV resistant
  • Solar and heat reflective


weberpas deco 322 is a heavy duty flexible acrylic elastomeric waterproofing coating derived from specialty polymer compounds. When applied, it forms a tough, highly flexible, seamless, durable elastomeric membrane for the protection of different kind of roofs and substrates. High reflectivity combined with excellent weather ability, UV resistance and strong adhesion make weberpas deco 322 an effective coating for providing long term reflectivity over a wide range of substrates.

Product Features

Scope of Use

weberpas deco 322 is suitable for the waterproofing and protection of different types of roofs and substrates such as concrete, metal and wood. The application substrate may be horizontal, inclined or having irregular shape.

The properties of weberpas deco 322 will be significantly enhanced by the incorporation of suitable reinforcement, like weber band.

Instructions for use

Surface preparation

Substrate (concrete, metal, wooden roofs, tiles,…) must be clean, sound and free from greasy matters and dust. Repair if damaged and remove all traces of paint, mould or oil which may affect the adhesion. Before the application the substrate must be sufficiently cured in a way that any shrinkage has already occurred.

Product application

Apply in two coats, each at an approximate rate of 0.8 kg/sqm, to provide a total of about 2 kg/m2(including the priming coat) weberpas deco 322 can be applied using a brush, roller, squeegee or airless spray equipment. The suitable method may be chosen depending on site conditions.


If not diluted before, the first coat of weberpas deco 322 should be diluted with 20% of clean fresh water to act as a priming coat. Ask Technical Department in case of questions. For metal surfaces, dilute it with 30%, to have minimum thickness.


All corners, patched areas or construction joints should receive mesh reinforcement, like weber band, between the 1st and 2nd layer of weberpas deco 322. Between 1st and 2nd layer of weberpas deco 322, wait for 24 hours (at 25°C temperature and 65% RH).
