Bostik esm is a solventless three component screed mortar based on epoxy resin technology.
bostik esm is an expoxy screeding material ideally suited for floors and walls subjected to mechanical loading and chemical exposure. Its usage is recommended for all factories, like fertilizers, paper, textiles etc. , in food industries like beverages, sugar and confectionaries, in water treatment and sewage treatment plants etc. Bostik esm can be used as a flooring where high
traffic is expected like highways,airportsetc.
• very good strength properties.
• local patch up can be done.
• negligible shrinkage.
• solvent free.
surface preparation :
concrete surface should be free from contaminants and dust by sandblasting. In case sand blasting is not possible, thorough abrading with a hard wire brush can be used, though it is not as efficient. Otherwise, acid etching using 1 part of hydrochloric acid with 2 parts of water can be carried out. The solution should be brush applied over the surface liberally and left in contact for 15 minutes. Then it is washed off with plenty of water followed by thorough drying with hot water. The pre-requisites for good adhesion of the coating are cleanliness, roughness and dryness of the surface. Unless these are ensured by proper surface preparation, a successful performance cannot be guaranteed. Apply thoroughly mixed primer e1 onto prepared substrate by brush roller. Mix thoroughly with slow speed stirrer, bostik esm, pre weighed base & hardener first and then add filler slowly. Continue to stir till uniform mix is attained. Spread mix mortar evenly on tacky primed surface for desired thickness by steel / wooden trowel. Wooden / steel reference guide can be used to maintain required thickness. Smoothen it up by pressing with steel trowel.
