5-10 m2 per Litre approx. for open or textured surfaces. 10-15m2 per Litre for sealed or more closed surfaces.

Coats – 2 to 3 normally

Alka TEN can be applied by brush, roller or spray. Application of the first and possibly the second coat should be carried out on falling temperature to aviod the possibility of bubbling from air escape from the substrate and to maximise pentration. Premature exposure to moisture from the substrate or atmosphere may result in whiteneing/clouding of the finished product. A trial area is recommended before proceeding. Apply evenly and aviod leaving any excess product on the surface. Recommend thickness of the coating film is above 1.5 mm, and the interval between each coating is 2-12h (depending on the weather conditions).

1-2 layers of glass fibre cloth or other carcass materials can be added in the middle of the coating. Generally, 1.5-2.0 kg/m² for 1 mm thick rubber liked membrane to form.
