At Mile High Coatings, preparation is the most important step in the painting process. We are committed to making sure the paint job you get will look great and last for years.
One critical step in the preparation process is selecting the correct primer for the particular area. Siding versus real wood can play a role. Tannin bleeding, stains, chalking and mildew are all factors that can affect the type of primer used.


Many homeowners think that “oil-based primer” is the only way to go when using a primer. Oil-based primer is ideal for exterior, wood surfaces because it absorbs and penetrates into the wood and creates a strong adhesion point for the paint. It should not be used on siding.

Shellac Primer:

Shellac primer is ideal when there is tannin bleeding and stains and the goal is to block the stain. In this case, we recommend the white-pigment shellac primer.

Water-based Primer:

There are many water based primers and these can be used for multiple cases and are ideal when there are many types of surfaces ranging from bare wood to painted surfaces.
