Spraying vs. Brushing House Exterior: Which is best?
An airless sprayer is fine to use, provided the siding stain or paint is back brushed (i.e., we spray first and then use a brush to work the stain or paint into the wood.) The sprayer will allow the stain or paint to be evenly dispersed, while brushing will work the product into the siding, giving the siding the best protection.
