Horizontal barriers with pressureless injection system KÖSTER Crisin Cream

Rising (or “wicking”) moisture is among the most frequently encountered causes of damage in masonry walls. The results are clearly identifiable through the spalling of plaster, damaged joints and bricks, and also through salt efflorescence and algae growth. Damage from rising moisture can be avoided by the installation of a horizontal barrier.

KÖSTER Crisin Cream is a very thin resin which penetrates into the smallest capillaries in the building material, stops the capillary action permanently and creates a hydrophobizing effect. KÖSTER Crisin Cream can be applied from inside and/or from the outside of the building. It is suitable in cases of high degrees of moisture penetration (95% +/- 5% saturation) and with all degrees of salt contamination.

In cases where damage is caused by rising moisture, the old plaster has to be removed from the wall. After the installation of the horizontal barrier, the application of KÖSTER Restoration Plaster is required. The KÖSTER Restoration Plaster allows the masonry to dry without damage. KÖSTER Restoration plasters are open to vapor diffusion and are hydrophobic. Salts remaining in the wall are absorbed by the KÖSTER Restoration Plasters so that salt doesn’t effloresce to the surface and doesn’t cause damage to the plaster or paint.

KÖSTER Restoration Plasters are available in different varieties (grey, white, fast and light). KÖSTER Restoration Plaster White is often used in older buildings without subsequent painting. KÖSTER Fine Plaster creates a smooth decorative surface and can be applied when desired to meet architectural goals. KÖSTER Restoration Plasters can only be painted over with breathable (open to vapor diffusion) paint such as KÖSTER Silicone Paint White.

Always adhere to the specifications in the respective Technical Guidelines.
