EFFE 70 is an organopolysiloxane oligomer based water repellent, antifouling protection having high penetration and low molecular weight (it does not contain silicone polymers) and is used for the impregnation of building materials of mineral nature both vertical and horizontal.
EFFE 70 is ideal to create a water repellent barrier against the absorption of rain water, thus preventing the formation of moulds and algae, without blocking the natural transpiration of the surface.
Following are some of the fundamental advantages of the efficacy and duration of the treatment:
- prevention against the formation of saline efflorescences, saline, moulds, and algae;
- high depth penetration;
- excellent resistance to alkali;
- dust-free time;
- possible use also on materials still slightly wet (even if in this case there is less penetration);
- the treated material’s permeability to water vapour (the reduction of the permeability is not more than 10% higher the initial value);
- does not form surface films;
- or colour variation of the materials treated (on some stones it may confer a slight wet effect).
EFFE 70 is long-lasting: for floors, it is measurable on 5 years; while for facing surfaces, it is 8-10 years. The removal of the old application is not necessary for reapplication.
EFFE 70 presents a limited surface pearl effect, since the low reaction speed does not allow complete absorption on the surface treated; this also allows obtaining good recoating with water paint within about 72 hours after the application, while there are no contraindications for solvent paints (we recommend preliminary tests on the compatibility with paints used).
Facing surfaces and floors in terracotta, all types of clinker, rough, red stoneware, bricks, natural and artificial stone, slate, cement, granite, antiqued marble, gaps between tiles and all absorbent building materials laid outdoors and indoors.
pores, to favour the penetration of the product. EFFE 70 is ready to use. Apply as is on dry supports (at least after 5 days from the last washing or rain), spreading the product with a brush, spraying (low pressure 2-3 bar) or roller. The application can be carried out in one or more solutions, waiting 4 hours between one and the other, (for facing surface wet on wet), being careful that the material is always well saturated. Distribute uniformly to prevent product stagnation. EFFE 70 is a permanent treatment, it can be periodically reapplied always on facing surface or clean and dry floor, without having to remove the previous one. If repainting with water paint, previously apply a breathable fixative.
