ISOVIT Lime

• Surfaces must be hardened, clean of dust, releasing agents, crumbling or unstable materials, efflorescences, as well as any type of material affecting the conditions of adhesion.
• The surfaces must be checked with a two-metre ruler, ensuring that there are no irregularities greater than 1 cm. If there are, the surfaces should be smoothed with REDUR H2FIBRA plaster on new constructions, or REABILITA CAL RB in the restoration of old buildings.
• Previously applied plasters must have a “trowelled" surface and cure for about 28 days, protected from the weather.
• For application on painted surfaces, the paint must have sufficient adhesion to support the new coating.
• Should the surface be an old ceramic coating, it must be ensured that it is sturdy, smooth and all parts adhere well to the surface. If this is not the case, the loose parts should be removed and the coating smoothened.
• If necessary, clean the surface with suitable detergents to remove oils and residues accumulated on the surface.

Apply to masonry and uneven surfaces (gradient no more than 1 cm every 2 metres)
Bond the panels (dimensions 1.0 x 0.5 m) with a broken line of mortar around the perimeter, adding at least two points of mortar in the centre of them. Provide for mechanical fixing with ISOVIT Bucha (recommended minimum – 6 per/m²).

Apply to even plaster or concrete surfaces
Simple continuous bonding should be carried out using a 10 mm jagged trowel, preferably placing the mortar on the back face of the panels. Provide for mechanical fixing with ISOVIT Bucha (recommended minimum – 6 per/m²).

Recommendations for bonding
The procedures for the development of bonding should ensure uniformity of surfaces, that the panels are level and without gaps and that there is no mortar between them.
