In cases where the final topcoat will be applied in the field, getting the material primed on all six sides is the best way to protect your investment. We will machine apply an alkyd primer to each board to protect the wood from moisture and potentially harmful UV rays. Once on site the material can be installed immediately giving you a 30-45 day window to topcoat the siding. Pre-priming the material in a factory will save you time and money versus field priming.
