Palight Trimboard does not require paint for protection, but it can be painted – using specific types of paint.
Be sure to read this entire page before purchasing paint or beginning painting.
PAINTING PALIGHT TRIMBOARD – GENERAL INFO
- Moisture cycling is a main reason for paint failure on wood. Because Palight absorbs no moisture, paints last longer on Palight than on wood (usually 3 to 4 times).
- Because Palight Trimboard does not absorb moisture, paint can take as long as 30 days to fully cure, depending on outdoor temperatures and humidity.
- Palram is not liable for paint used on Palight Trimboard and/or the results of its use
PREPARING THE SURFACE FOR PAINTING
No special surface preparations are required prior to painting. However, fine dust can collect on the surface of any PVC trimboard due to static. To ensure a dust-free surface that will promote good paint adhesion, leave the EverClean™ Protective Film in place and remove just prior to painting.
If the EverClean Protective Film has already been removed, then prior to painting, wipe trimboards with a rag moistened with isopropyl alcohol, or mild detergent and water.
Use paints that are 100% acrylic latex or acrylic latex with a urethane additive.
PVC trimboard can become damaged as a result of excessive heat absorption. Using the wrong paint can cause heat absorption beyond the specification of any PVC trimboard.
This is why it’s very important to use either:
- Standard latex paints with a Light Reflectance Value* (LRV) of 55 or higher. Paints with an LRV of less than 55 will absorb more heat, and can lead to damage or warping of any PVC trimboard product, including Palight Trimboard
— OR —
- A latex paint that is specifically designated as “safe for vinyl siding.” Sherwin-Williams has its VinylSafe™ paint line. PPG has its SidingSafe™ paint line. Both perform well on Palight PVC Trimboard.
PPG Paints has provided SidingSafe™ paint formulations to match our Palight Trimboard Sand and Clay colors. See chart below.
Always tell your paint provider ahead of time that you want paint that is safe for PVC/vinyl.
* LRV is a measure of the lightness of an object and ranges from 0 (black) to 100 (white).
PVC EXPANSION & CONTRACTION
Using standard (not “safe for vinyl siding”) paints with an LRV of less than 55 can cause significant damage to PVC trimboard.
All PVC products expand and contract to some degree. If you follow our installation guidelines, you can limit the variance to just 1/8". Longer runs of uncut boards will expand and contract more than shorter runs.
If you do not fasten PVC trimboard properly, and if you do not account for future movement, problems with gapping or buckling can occur. This is especially true if the board is very hot or very cold on installation. In these cases, be sure to account for future expansion or contraction when gapping boards.
There is no hard and fast calculation, but generally, you will need less gapping when installing hot boards, and more gapping when installing cold boards.
