How-To Steps

1. Substrate Preparation: Begin by sanding bare wood with 220 paper grit to ensure optimal adhesion. If staining is required, apply solvent-based stains from the TM—M006 or TM—M007 series, or water-based stains from the TY—M001 or TY—M003 series. For pigmenting the product, use solvent-based colorants from the TM—M005 series.
2. Product Preparation: Mix RENNER FL-25M269 (100 parts by weight) with hardener FC—M003 (50 parts by weight) and thinner DF—M005 (20 parts by weight). Ensure thorough homogenization before application, especially after prolonged storage.
3. Application: Apply the mixture using an air gun, airless, or airmix system. Apply up to a maximum of 3 coats, with each coat not exceeding 150 g/m². Allow an interval of 1 to 3 hours between coats to ensure proper drying and adhesion.

Recommendations
For optimal performance, ensure the product is well-homogenized before use, particularly if it has been stored for an extended period. For applications during summer or in conditions of high temperature and humidity, consider using alternative thinner DF—M003 for improved flow and drying characteristics. Always ensure adequate ventilation during application and drying. Store in a cool, dry place. The product has an unlimited shelf life, but proper homogenization is key for best results.
