Final Finish
- Freres does not provide in-house staining or finishing services
- Apply stain to a small test section as different colors of stain bring out different characteristics in the wood
- When finish sanding is needed, sand in the direction of the grain using 120 grit sandpaper
- Follow the application directions for whatever finish product used
Weather Conditions
- MPP panels are susceptible to adverse weather conditions and precautions must be taken to protect them
- If unprotected, rain and moisture will cause staining of MPP, as with traditional plywood
- If bolts are used with steel connections, ensure they are free of oil to avoid staining
- Galvanized bolts and connectors will minimize staining
UV Damage
- If a portion of the panel has been left uncovered in the sun, UV damage will occur
- All wood species change color over time as a result of exposure to natural light and oxidation of the wood fibers
- Over the long term, the color differences will even out and in most instances will disappear
- If it is deemed necessary, the color difference can be corrected in the short term by manually sanding the affected areas to remove the sun-tanned marks on the beam
