- Installation Over Concrete
Preparation:
1. Curing of concrete shall be by means of water cure or dissipating compounds. Curing compounds shall be approved by an authorized representative of Excellent Coatings International
2. Concrete shall be cured a minimum of 28 days prior to installation of the Excel-Coat Primer 120 unless approved by an authorized representative of Excellent Coatings International.
3. Concrete finish shall be a power metal float followed by a light steel trowel and fine hair broom finish, or equivalent.
4. Concrete surfaces shall be free of excessive roughness, voids, protrusions or exposed aggregate.- Applications
1. Open both base and hardener containers. The base container is not full, in order to pour the contents of the hardener container into the base container.
2. Using a drill motor and a mixing attachment, mix the resin and the catalyst thoroughly.
3. Using care, apply mixed primer by roller or brush creating a thin, even coat. One gallon kit should cover approximately 250-350 square feet.
4. Allow primer to become tacky at least 1-3 hours at 70°F (12°C) before application of the Excel-Crete material. Excel-Crete should be applied while primer is slightly tacky. For epoxy or urethane coatings, allow primer to become tack free. This process takes 2-6 hours.- Installation Over Existing Coatings
Preparation:
1. Existing coatings shall be tightly adhered with no cracking, peeling or chipping. Surface shall be clean and dry. It is recommended that existing coatings that are to be re-coated be approved by an authorized representative of Excellent Coatings International.
Note: If primer cures longer than one day before application of acrylic materials, then re-prime surface.
