Mold and mildew may be a larger problem on some deck surfaces. If so, this issue must be addressed quickly during the prep stage, or else the mold can create complications with the deck coating material. If mildew is sealed under the deck coating, it can grow unchecked resulting in a potential health hazard. The mildew and mold can also weaken a deck coating’s adhesive qualities.
Repair Damage on Decks before Coating
Damaged or marred surfaces must be repaired or replaced before starting the deck coating process. Loose materials or broken materials can create serious complications in the deck coatings integrity. Depending on surface conditions, sand or shot blasting may be necessary to thoroughly clean the surface and prepare it for deck coating.
Most deck coating professional companies prefer to do their own prep work before application. By taking care of the cleaning and sanding, the professional contractor is ensuring and guaranteeing that the deck coating will be able to take day to day wear and tear.
