Polymer-modified, cement-based mortar for the levelling and reinforcement of surfaces to be covered with microcement toppings.
It exhibits high initial and final adhesion strength, high elasticity, and moisture and frost resistance.
It is classified as general purpose rendering mortar type GP CS IV according to the European standard EN 998-1, as well as mortar for the protection of the surface of concrete structures according to the European standard EN 1504-2 (principles MC-IR).
It is suitable for the preparation of surfaces to be covered with microcement topping mortars on floors and walls, but also as a surface treatment of concrete structures before painting.
It is applied on any type of substrate, e.g. concrete, render, masonry, cement/gypsum boards, wood, porcelain and metal.
On very absorptive or non-absorptive substrates, like wood, ceramic tiles or metal, it is necessary to treat the substrate with a suitable primer before applying SD 300.
