Blasting vs Sanding
Blasted wood is the best prep method for all types of coatings and for longevity
Once wood is blasted it opens up the pores allowing the stain to penetrate further and deeper into the wood cells, ultimately providing superior protection from harmful UV Rays and moisture.
The applicator ends up using a lot more stain product because the wood is now absorbing more product.
This will ensure your finish lasts for 10 years or more prior to a maintenance coat.
When wood is sanded, frequent maintenance is required.
Once wood is sanded smooth it closes the pores. The problem with this method is that the stain doesn’t penetrate deep enough to provide long term protection.
The stain will work more like a film coat instead of a penetrating coat, meaning frequent maintenance is required.
