Boero Polywood Two-component Wood Preserver. 1 Lt. 000 Transparent.

It is a two-component transparent sealer used for impregnating high-quality woods, marine polywoods and MDF panels. It penetratse and isolates and produces surfaces that are easy to sand and to be covered with mono or two-component products for achieving either coloured or clear surfaces. This product is mainly used on new wood or wood that has been completely sanded down. It must absolutely not create a layer on the surface but it has to penetrate inside the surface.

Note: The product is provided in two tins to be mixed entirely and carefully before use. The eventual dilution must be done after mixing the two components together. The physical data of two-component products refer to the components after they have been mixed together.

SURFACE PREPARATION
New wood: Apply directly on clean wood.
Old wood: Complete removal of old painting cycle with paint stripper, flame, scraper or sanding. Clean and dust.

Painting cycles
New wood: Apply a coat of Polywood diluted by 10 - 20% and after 1-2 hours apply a second coat. After 6-8 hours proceed with sanding and subsequent application of one or two-component cycle.
Bare old wood: Apply a coat of Polywood diluted by 10 - 20%. After 6-8 hrs proceed with sanding of the support with subsequent application of one or two-component cycle.

APPLICATION CONDITIONS
Per evitare il formarsi di condensa, la temperatura del supporto deve essere superiore al punto di To avoid the formation of condensation, the temperature of the surface should be at least 3 °C above dew point. During the application and curing the min. ambient temperature should be 15 °C, or higher than 30° C; substrate temperature must not be lower than 10° C since curing is reduced at lower temperatures. Application is not advisable when relative humidity exceeds 80%. The thermo-hygrometric survey should be carried out near the surface to be coated. It is important to be sure there is sufficient ventilation when the application takes place in closed areas.

SAFETY RULES
In order to protect personal health it is advisable to comply with the EU DPR 303 and 547 regulations. Avoid, for example any contact of the product with the skin and eyes. Use in well ventilated areas,in enclosed areas use aspirators, fans and air ventilators. Wear masks, goggles, gloves while applying the product.

NOTE
Ensure that the product does not come in contact with water, chemical products or undergoes mechanical stress before the curing is complete. The wet film thickness is referring to an undiluted product. In case of dilution, this value increases.
