Myths About Exterior Stains

High quality wood stains do not peel
False
Regardless of the product used, if the surface is not prepared properly and the wrong application method is used, it could peel. Whether your wood was previously stained or not, you must start by washing the surface. It is important to remove loose grey wood fibers and stains caused by mildew, dust and moss since these contaminants will keep the stain from adhering properly.

New wood surfaces do not need to be sanded before staining
False
To remove imperfections and prepare wood’s pores to receive stain, the new wood surface must absolutely be sanded using 80 grit sandpaper. On vertical surfaces use 120grit sandpaper for a finer finish. Check that you have sanded enough by sprinkling water on the surface - if it pearls then you must continue sanding, if the water penetrates the wood then the stain is ready to be applied.

Applying stain with a roller is much faster than with a brush
False
Since wood warps with time, it becomes difficult to reach certain areas with a roller. A brush is the best tool for applying stain evenly. There are specifically designed brushes whose length and width allow for quick application. You can also attach the brush to to a long handle so you can work standing up - way more comfortable.

It is better to apply more than the two coats the manufacturer suggests
False
A coating that is too thick compromises one of stain’s main advantages - it's flexibility, which allows it to follow woods movement without cracking or peeling.

Exterior Stain can be applied on any nice summer day
False
If it is warmer than 25C or if the surface to be stained is very hot to the touch, stain will not have time to penetrate the wood deeply or blend with the former stain, which will lead to peeling. As well, if the stain dries too quickly it is difficult to apply and will leave behind brush marks and and uneven look.
