HORIZONTAL BARRIER

WITH THE

ISOTEC SPECIALIZED PARAFFIN

Paraffin is a very fluid wax, which permanently plugs
the pores of the masonry. Capillary moisture doesn´t
stand a chance anymore. The patented procedure can
be executed exclusively by ISOTEC authorized professionals.

Renovation plaster dries moist masonry

Applying renovation plaster:

The problem: Peeling plaster caused by salts

The salts are transported into the existent plaster through capillary moisture. With the evaporation of the moisture, they may crystallize and, by crystalline pressure, cause further peeling of the plaster. Our ISOTEC Renovation Plaster surrounds the salts, prevents further peeling and permits the masonry to dry. 

Our 1st step: Preparation

Initially, we remove existing coats of paint, plaster and other disturbing materials from the masonry. This measure also removes most of the damaging salts. We then prepare the masonry for the application of the rough cast. 

Our 2nd step: Improving adhesion

Perfect adhesion of the renovation plaster on the masonry is imperative for a permanent renovation success. For this reason, we apply a roughcast for better adhesion before our ISOTEC Renovation Plaster. This is done in a net-like manner in order to ensure an excellent adhesion of the renovation plaster.

Our 3rd step: Plastering

At last, we apply our ISOTEC Renovation Plaster to the wall. Depending on the degree of salinity, the plaster is applied in one or two coats. Due to its diffusion capacity, the ISOTEC Renovation Plaster ensures the drying of the residual moisture of the masonry.

Restoration: Our satisfied customers

Rectory | Damage: mushroom-related (hygroscopic) moisture

The ISOTEC Group has successfully sealed more than 85.000 properties in Germany, Austria and Switzerland in the last 25 years.

The historic rectory of Pöcking/Germany had been in desolate condition. Ascending and laterally penetrating moisture, the efflorescing of salts as well as mould left the building practically useless. The renovation concept of ISOTEC, in which the ISOTEC Renovation Plaster was applied as well, permitted a quick and pleasant utilization of the house again.

ISOTEC Renovation Plaster

Although the source of the moisture damage has been removed, it will take a while for the masonry to dry completely. Depending on the type of masonry and the ventilation, it can take up to two years for the moisture within the cross-sectional area of the wall to completely dry.

The high air void ratio of our ISOTEC Renovation Plaster permits the crystallization of salts during the drying phase without causing any damage. For this reason, the renovated space may be used again already during the drying phase.
