Substrates

Conventional cement-base or brick fabric substrates.
Substrates must be resistant enough, stable, healthy and clean. Free of dust, release agents, organic products, etc.
In case of heavy heat, wind or very absorbent substrates, it is advisable to moisten the substrate and wait until the water film is totally absorbed.
In singular points (joints between different materials, slabs, pillars, shutter boxes, door and window frame angles, etc.) reinforce the mortar with fibreglass mesh to prevent cracks.
On slightly porous substrates, apply a suitable primer, or improve the roughness by mechanical means.
Do not apply on top of plaster or paint.
