For waterproof (D4) mutual (surface) joining of practically all types of building materials, such as wood, gypsum, (natural) stone, (cellular) concrete, metal, hard foam and various synthetics. Suitable for internal and external applications, such as plate and insulation, roofing sheets and cover profiles. Also for less-fitting joints (for example, unplaned wood) and uneven materials. Ideal for vertical applications. The adhesive cures under the influence of moisture. Because of this, at least one of both surfaces needs to be a porous, moisture-containing surface. D4: Interiors where flowing water or condensation are present over long periods on a regular basis. Exteriors exposed to the influences of the weather, providing effective protection for bonded wood.

Not suitable for joining polyethylene (PE), polypropylene (PP), PTFE and nylon (PA).

The ambient temperature, the adhesive and the materials to be bonded should not be lower than +5°C. Level of wood humidity between 10% and 18% (up to 25%.

Surfaces must be clean, dust-free and well-fitting. Degrease oily types of wood with GRIFFON Cleaner. Roughen non-porous materials.

Cartridge gun, fine-toothed glue spreader (1 mm), brush or roller, clamp or press.

5-6 m²/kg

Apply adhesive thinly and evenly on one side using a sealant gun. If necessary, spread further using a fine-toothed glue spreader (1 mm), brush or roller. Moisten the side to which no adhesive has been applied with a damp cloth. Assemble joint within 2 minutes and clamp or press for at least 15 minutes. Apply adequate coating to glued joint for maximum water resistance.

It is recommended that rubber or plastic gloves are worn.

Remove wet adhesive residue immediately with GRIFFON Cleaner. Dry adhesive residue can only be removed mechanically.

Store dry in sealed packaging between +10°C and +20°C.
