Priming the exterior of timber before painting is the most important thing to remember when having new timber installed around your home.
For example, if you’re using pre-primed timber for a fascia board or a handrail, all bare areas including end grains need to be fully primed with a suitable primer/sealer. This is BEFORE the timber is assembled, not after.
After installation fill gaps with a flexible, paintable filler and nail holes with an exterior grade filler. When everything dries and the weather is looking good, continue on with your final painting.
I can’t stress enough how important this is! Moisture in timber is what causes rot, decay and can even be an entry point for termites.
Follow these simple tips and it will last for many years!
