Anti-humidity protective for absorbent stone materials
Protective breathable water repellent for absorbent stone materials: cotto, absorbent stone, plasters, cement and cement agglomerates placed inside and outside. It does not alter the appearance of the material.
CHARACTERISTICS AND USE
IDROWIP is a water-based protective impregnator which forms a solid, water-repellent, breathable chemical barrier on absorbent stone materials: cotto, absorbent natural stone, cement, mineral plaster.
- it avoids and contrasts the rising damp (and consequently the formation of salt efflorescence, crusts, patinas, algae, etc.);
- reduces drastically water absorption (ex. rains, water-soluble substances, cement grouts, etc.);
- has high chemical inertia and resistance to atmospheric agents;
- does not alter the appearance of the material.
On highly absorbent materials it is recommended to apply the product in the phases prior to laying or grouting the material, in order to protect the surface and facilitate and speed up the subsequent processing steps.
INSTRUCTIONS FOR USE
Shake before using. It can be applied by spray (recommended) or cloth, sponge, fleece to spread wax, rag, evenly wetting the surface to be treated, following the ab-sorption of the material. Redistribute any excesses on the material with a cloth during the drying phase. Normally it dries in 4 – 8 hours depending on the aeration.
It is applied to saturation of the material:
- 1 coat: on medium-low absorption materials;
- 2 coats: on high absorption materials.
The application of the second coat must be carried out as soon as the first one has been absorbed and without waiting for the surface to dry (“wet on wet”). Avoid that the surfaces just treated are wet from rain before 12 hours.
Depending on the the absorption of the materials:
- on poorly absorbent material 1 lt / 8 – 15 m²;
- on very absorbent material 1 lt / 4 – 8 m².
1 lt – 5 lt – 20 lt.
