Fields of application
Formation, by injection, of horizontal chemical barriers for stopping capillary rising damp in building renovation and damp brickwork; water repellent and reinforcing treatment with slightly alkaline porous building materials: bricks, tiles, terracotta and crude ceramic materials, etc.
Allowed supports
Bricks
Tuff
Mixed walls (bricks and stones)
Stone walls
Preparation of supports
Remove the existing plaster, only if necessary, up to at least one metre above the line of evident damp.
Draw a line parallel to the outside kerb or inside flooring, at a distance of about 10-15 cm from the same. Prepare drilling points at 12 cm distance from one another on the traced line. The inclination of the holes should be about 20° down. The depth of the holes should be approximately 4/5 the thickness of the wall to inject. The drill bit to be used must have a diameter of 18-20 mm. Once the holes are finished, the dust produced by drilling is required to be eliminated.
Mode of use
The product can be diluted with demineralised water or with a hardness less than 35°F up to a maximum of 15-20% (it is recommended for use preferably without dilution). Proceed with the pure product or with the solution obtained, with low pressure injections by airless pump (manual or electric), directly into the designated holes in the masonry.
Consumption may vary depending on the characteristics of the masonry and its thickness. By way of example, for 50 cm thick masonry, the indicative consumption of the aqueous solution is between 17 and 20 l/m.
Consilex Barrier-A requires an adequate and as lengthy an exchange as possible with the atmosphere, for the hydrophilic-hydrophobic transformation: schedule an adequate waiting time prior to sealing the injection holes and coating the brickwork. It is advisable to create the chemical barrier with Consilex Barrier-A- when work commences at the construction site and to close the injection holes a few days before ends.
Apply on porous media, with pH not exceeding 8.
Protect glass and aluminium surfaces from contact with the product.
