- Applications
Apply to freshly poured concrete as soon as surface is finished and will support foot traffic. Strengthens concrete by promoting hydration. Top coat with epoxies and urethanes, polyurea, polyaspartics.Cures to a matte finish.
- Application Procedure
- Surface Preparation: Not required when coating fresh/green concrete. In order that a coating system can wholly fulfill the job it is intended to do, i.e. to protect the substrate against damage, the substrate and the protective layer must adhere as tightly as possible. Failures due to peeling, adhesive loss or disintegration usually are connected to lack of cleaning, interfering materials or failure to produce a mechanical “tooth” for the new application. Due to the unique molecular structure of B3 Primer this problem can be eliminated. Cured Concrete: Before coating is applied, inspect the top surface of the substrate and treat as necessary to remove laitance, loose material on the surface, grease, oil and other contaminant's which will affect bond of coating. Remove oil and grease with commercial grade alkaline cleaner; thoroughly rinse and dry. Prepare all concrete surfaces by sandblasting, bead blasting, acid etching with a 10-15% solution of muriatic acid or high pressure wash (min. 2500 psi). (Caution: Use adequate respiratory, eye and skin protection when using etching solutions, sand blasting, or bead blasting.) After the preparation and cleaning of the substrate it is advisable to prime the surface as soon as possible. Its purpose is to plug the capillaries and pores in the concrete, to bind back the dust and to make sure the following coat is securely bonded.
- Mixing: Combine part A with part B . Mix with a Jiffy Mixer at 300-600 rpm for 3 minutes. After combing the A & B Components fill the remaining head space of the gallon can with water. Slowly add water while mixing. Mix for 3 minutes. Primer has a useable pot life of 60-75 minutes. Discard material not used within hour.
- Application: Squeegee followed by back rolling to the rate of 200 sq/ft/gallon yields a dft of 3-4 mils.
- Cleanup: Clean all equipment immediately after use with water .
