All surfaces to be treated must be clean and free from dirt, moss, mildew, laitance, efflorescence, and any other contaminate that may interfere with the penetration or reaction of Stain Block Elite to the applied surface. Remove all dirt, oil, paint or sealers with appropriate cleaner, chemical stripper or abrasive blasting. If muriatic acid has been used the surface must be flushed with clean water and neutralized with a pH neutralizer. After cleaning, allow surface to dry 24 hours prior to sealer application. Allow new concrete to cure for at least 28 days before application of sealer. Protect greenery from over spray.
Not required. Use as is.
Stain Block Elite can be applied with a brush, roller, or most types of low pressure, hand pump, spray equipment. Do not aerosolize (vapor like mist) with airless spray equipment. On dense surfaces one coat is all that is required to seal and protect the surface. If a second coat is necessary due to extreme porosity, apply immediately after the first coat has soaked in. For small areas, a pump-up garden sprayer is convenient. For large commercial installations a large capacity pump spray system is recommended. Do not apply Stain Block Elite during wet weather or when surface temperature exceeds 80°F. Application to a damp surface or incompletely cured concrete may cause a hazy appearance or loss of adhesion. Air and surface temperature should be between 50° and 80°F for 24 hours following application.
Brush: Synthetic bristle brush
Roller: 3/8″ nap roller
Low pressure pump sprayer
200 – 1000 sq.ft./gal
Theoretical is 200 to 1000 sq. ft./gal. depending on texture and porosity of the surface to be painted and method of application. For exact coverage rates, a measured quantity to proper application over a known area will provide a square foot coverage rate for a specific job.
Dry Time: 30 mins to 3 hrs
Rainproof: 12 hrs
Cure Time: 48-72 hrs
Water Pepetration Test:
Drop a small amount of water on the sealed surface. If water penetration occurs or if water does not bead up on the surface, the application of additional sealer is required.
Minimal maintenance is required except for sweeping the surface of dirt and wiping up spills soon after they occur. Perform “Water Test” once a year. If test fails, reapply Stain Block Elite.
