Product selection is tantamount to achieving a quality result. Assessing the ultimate objective of the finishing project and staying on course will help simplify the choice. There are a great number of considerations involved on every project, specific surface preparation products and bonding products assure a good start leading to success. The best top coat selection can fail quickly over the wrong primer. Products are designed for application to specific surfaces and with specific performance and durability standards. A professional will consider things such as climate, sun exposure, wear ability and hardness, wash ability, environmental issues, sheen and color retention, compatibility with adjacent surfaces and ingredients that relate to rust, mildew, and insect inhibition. Concerns regarding air quality issues should be addressed at this time as well. Product selection is far more involved than deciding what color and how shiny you would like. The challenge of staying informed about product improvement and reformulation requires a constant effort to keep up with changes affecting adhesion, durability, quality and environmental concerns.
