How Commercial Painters Avoid Osmotic Blistering for Epoxy Coatings

Osmotic blisters can be the kiss of death for many epoxy coatings.  Those blisters create weak spots on the coating, which increases the likeliness of the epoxy coating rupturing.  But an experienced commercial painting contractor will have the skills and foresight to prevent these blisters from occurring.

Osmotic blisters are unsightly little bumps that appear on epoxy floors.  And although they may not seem to be too problematic, they’re actually the first step in dealing with coating failure.

A blister occurs when there is too much hydro static pressure pushing build up between the coating and the concrete.  That pressure causes the coating to separate, or delaminate, from the concrete.  This separation creates a weak spot, which can then rupture.  And once a coating is ruptured, moisture can enter, and cause the remaining floor to separate.  Which is not nearly as valuable as worm castings.
