Before you use this product
- All surfaces to be finished must be clean and free of oil, dust and contamination that may cause fisheyes or poor adhesion.
- Clean surface with denatured alcohol or fresh water. Allow surface to thoroughly dry before proceeding.
- Fine sand surface to be finished with the appropriate grade sandpaper based on the type of final finish required.
- If the surface to be finished has a grain-filling type glaze, sealer or paste; ensure that the systems are compatible with one another by preparing a test panel before proceeding. - Certain solvent-based fillers and glazes may prevent proper adhesion of the topcoat if not thoroughly cured.
- Ensure that grain fillers have been sanded with a minimum of 400-grit sandpaper and all contamination is removed.
- Oil-Based glazes should be air-dried and tested to ensure proper early adhesion of the water-based topcoat.
- Pigmented base coats such as pigmented lacquer or acrylic sealers should be dry and lightly sanded to remove surface defect.
- Follow the manufacturers directions for overcoatings pigmented sealers and base coats.
Spray-apply each coat of SuperClear 9000 with HVLP, Conventional or Airless/Air-assist spray equipment. Consult with your spray gun manufacturer for proper gun set-ups based on coating viscosity and intended use.
- Spray gun operators must wear a NIOSHA approved respirator during the spray application of this material. Consult the Material Safety data Sheet of this material for safety and health procedures.
- Can be fortified with 2 to 5% of CL100 Cross-Linker
- After surfaces has been prepared remove all dust with a wax/oil-free tack cloth.
- Gently mix SuperClear 9000 before using.
- SuperClear 9000 can be applied using a spray gun, poly-bristle brush ou varnish roller. SuperClear 9000 can be sprayed without reducing with water or SA5 Spray Retarder. However, additions of SA5 Retarder may be required to slow-down the system if the polyurethane is drying too quickly during high temperature applications.
- Apply the required number of coats of SuperClear 9000 to obtain the desired film-build and final look. A minimum of 2 coats applied at 2-4 mils per wet coat is required to obtain a thin film set. There is no limit to the total number of coats of product that can be applied. Allow each coat to dry for a minimum of 45 minutes before recoating. Sanding between each coat is not necessary unless contamination has effected the film formation, or if the last coat has dried for more then 24 hours. Sand with 600-grit sandpaper to remove surface imperfections, runs, sags and contamination. Remove sanding dust as specified and apply final coat as required.
Spray Gun Set Up Recommendations:
- Compressed Air HVLP: 1.3mm – 1.5mm needle set and corresponding air cap.
- Air-Assisted Airless: .09 - .11 tip set.
- Airless: Fine tip set.
Consult with spray gun manufacturer for specific air pressure settings
Allow each coat to thoroughly dry before applying additional coats of polyurethane. For best results apply during low humidity conditions. If whitening or blushing occurs in the semi-cured coats, allow lacquer to return to a clear state before applying additional coats. Best temperatures are 60°-80°F. Complete chemical cure time is after 100 hours within these temperature ranges.
