Topcoat Application Tips
Customers find that SPDI / CureUV waterborne coatings dry just as fast as a lacquer, but with superior abrasion and chemical resistance.
The topcoats include an all acrylic system, an aromatic polyurethane based system, and a non-yellowing aliphatic polyurethane system. They offer perfect balance of Performance and Environmental Sustainability to allow conformance to the program requirements of the South Coast Air Quality Management District (SCAQMD), Greenseal, LEED & KCMA approved.
As we are an Application Specific Advanced Coatings (ASAC) manufacturing facility, we customize our coatings to fit you & your customer’s needs to provide you with:
- 40% solids specifically formulated for your production process
- More scratch & chemical resistant
- More coverage per gallon
- Very Fast dry time (sand time within 10-20 min)
- No milky appearance
- Sealer & Topcoat in 1 product
- Less waste
- 1 material process
- Remove 1 current step
- Increase production & up time
If Using As a Self- Sealing Topcoat
- It is recommended to apply the Sealer / Topcoats to a wet thickness between 3 – 6 mils (0.003”-0.006”). As a visual aid the wet topcoat application, when applied properly will appear orange peeled, but will however, dry smooth.
- Let dry 10-25 minutes depending on application of mil thickness. Sand to 220 grit.
- Apply the Sealer / Topcoats to a wet thickness between 3 – 6 mils (0.003”-0.006”) and let dry 10-25 minutes depending on application of mil thickness. Depending on application thickness, project should be stackable in 1 hour. Most topcoats are buffable if needed.
If Using A Sealer then Topcoat
- Pre-sand sealer to 220 grit and one topcoat application wet thickness between 3 – 6 mils (0.003”-0.006”) is sufficient for quality results. Two topcoat applications will result in exceptional surface finish quality. Most topcoats are buffable if needed.
Spray hoses must have a minimum of compressor oil and as discussed above, it has been noted that residues from solvent based coatings left in the fluid lines have been “cleaned” and removed with the use of the SPDI waterborne wood coatings. If the final coating surface is not uniform, check for surface contaminants on the wood substrate and any possible contaminants from the application equipment.
