Description

Transparent formulation based on aliphatic polyurethane resins. It resists ultraviolet rays, acid rain and the action of various acids (for further details contact Sivit Technical Assistance).
FINISOL TRASPARENTE SATINATO It forms a film that maintains good flexibility and good resistance to abrasion and scratching. It contains UV filters that preserve the surface from photooxidative degradation.
Satin appearance.

Use

Painting of concrete floors.
Finish for resin coatings.
Dustproof impregnation of cement and brick products. Particularly suitable for battery storage areas.
Protection of metal surfaces not subject to corrosion.

Support

The substrate must have a minimum compressive strength of 25 N/mm2 and a tensile strength of 1,5 N/mm2.

Preparation of the support

Each support must be cleaned, degreased and free of old coatings during detachment.
Abrasive superficially to promote adhesion.
It is recommended to use abrasive papers with a grain greater than 150, clear if possible. After abrasion completely remove dust from the surface.
As top-coating of resin coatings, it is necessary to proceed with the application by verifying the coating time of the previously applied product.
Concrete and brick surfaces must be solid, seasoned, leveled, absorbent, not polluted by oils, dust or other substances. Mechanically prepare the surface by sanding or grinding.

Application

Combine the two components (A+B) and mix using a mixer drill for 1 minute.
To obtain a rough and non-slip surface, it is necessary to add, at the time of preparation of the 2 components, 3-5% of SFERETTE DI VETRO FINI or 10-20% of QUARZO B0/B1 (see table).
Avoid preparing partial mixtures of the product in order not to incur accidental errors, which could lead to a failure or complete hardening.

N.B.: the application of the product by brush originates a film with a higher final gloss than the roller application.

Attention: by virtue of the nature of these types of product, particular attention should be paid to the time of drafting, in order to avoid imperfections such as rollers, overlaps, gloss differences, etc…
In general, proceed to distribute the paint on the support homogeneously in the right quantity; when joining the newly painted area, take care to resume the painting a few centimeters away in order to discharge the excess product and then connect with the previous area by blending and dosing the quantity applied carefully. Do not wait too long for overlaps, always paint "fresh on fresh".
In the realization of large surfaces, the coordinated movement of several applicators is required.

Warning: the product contains solvents, it is therefore necessary that the applicators wear the appropriate respiratory protection devices indicated on the Safety Data Sheet.
It is also recommended to compartmentalize the work areas appropriately, especially in the hours immediately following application and in the 2-3 days following.
During the evaporation phase, the nature of the solvents used can create annoying odors for non-experts present in nearby environments.
It is recommended to ventilate the premises well for at least 7 days after painting.

Notes: If component A needs to be transferred from its original packaging, mix carefully in order to homogenize any sedimented opaque agents and thus obtain the nominal gloss value.
