PLASTOTHERM is supplied in 25kg bags.
Consumption:
Each 25kg bag will cover approximately 5 square meters of surface at 3 mm thickness.
Storage:

Surface preparation
Remove all loose concrete, grease, oil, paint, dust, form release agents or any other material that might affect proper bond.
Mixing
Pour into container about 5.5 Liters of clean water then slowly add 25kg of PLASTOTHERM and mix till obtaining a homogeneous mix using a slow speed electric drill. Mix till a smooth, trowelable consistency is obtained. Allow the mix to stand for 5 minutes then remix again. Do not use any additives. Do not mix more material than can be applied within product open time. Partial mixing is not recommended.
Application
To fix the insulation board to the wall, apply spots of material to the back of the board at least 5 mm thick and 50 mm in diameter, making sure that the material covers minimum 50% of the board. An alternative method is to cover the entire back of the insulation board with the product using a 10 mm notched trowel. Place insulation board on wall and push firmly. Using a block of wood, apply equal and even pressure to allow maximum bond to be achieved. After fixing the insulation board to the wall, wait for 24 hours before coating the face of the insulation board.
Cut the mesh fabric into pieces that are manageable. For lightweight to medium weight fabrics, allow for a 50 mm overlap. Heavy mesh fabrics do not need to be overlapped, however, care must be taken to fix the edges firmly together. Using a flat stainless steel trowel, apply Base Coat of PLASTOTHERM to the entire face of the insulation board to a uniform thickness of 2 – 3 mm. Immediately place the reinforcing mesh against the wet PLASTOTHERM mixture. Trowel from the center to the edges with the curve of the mesh against the wall, avoiding wrinkles. Apply until the mesh is fully covered and not visible. The overall minimum Base Coat thickness must be sufficient to fully embed the reinforcing mesh. Allow Plastotherm coat with embedded reinforcing mesh to dry hard (normally 24 hrs.) prior to application of decorative top coat.
Curing
PLASTOTHERM is self-curing. Do not mist with water or damp cure. Under average drying conditions +25ºC and 55% R.H. PLASTOTHERM will dry in 24 hours.
Cleaning
Tools and equipment should be cleaned with water immediately after use. Hardened materials should be mechanically removed.
PLASTOTHERM is a cement-based product.
During application, wear appropriate protective clothing, goggles, gloves and respiratory equipment if necessary.
In case of contact with skin, rinse with water and again wash thoroughly with soap and water. In case of contact with eyes, rinse with plenty of water and seek medical advice accordingly.
If ingested, obtain medical attention immediately. Do not induce vomiting.
