Surface Preparation: All surfaces must be clean, dry, and free from dirt, mildew, dust, and other foreign matter. Previously painted or stained surfaces should be prepared by removing all loose or peeling debris. Chalky surface residue should be cleaned with a scrub brush, rinsed and allowed to dry. Use Superdeck Wood Brightener to remove discoloration from tannic acid and nail head rust stains. New wood should be primed immediately and not allowed to weather. All wood surfaces must be completely dry before application of Super Prime Stain Blocking Primer.

Mildew: Remove all mildew stains using Superdeck Wood Cleaner. Mildew is not caused by this coating and does not represent coating failure. This product cannot prevent mildew growth that is already present on the wood surface if not properly cleaned prior to application of primer. However, this primer does contain a highly effective mildewcide to inhibit the growth of mildew on the coating's surface.

Extractive Bleeding: Some wood species such as redwood, cedar, and fir contain natural water soluble extractives which tend to migrate or bleed to the surface and cause discoloration to the coating. This product is designed to retard extractive bleeding. However, extractive bleeding is not caused by the coating and does not represent coating failure. Any extractive bleeding can be easily removed using Wood Brightener.

Application: Product is supplied ready to use, no thinning is necessary. Product should be shaken or stirred before and during application. If the job requires more than one batch, intermix containers to ensure consistency. Always test a small area to ensure dry time. Apply using a high quality natural bristle brush, roller, or professional spray equipment. Back rolling or brushing is suggested when spraying, working the product smoothly and evenly into the wood to ensure proper penetration and a uniform appearance. Always maintain a wet edge, starting at one edge and following through to the end of the boards to avoid lap marks. One coat is sufficient for most wood surfaces. However, two coats may be necessary on rough sawn surfaces or woods containing high levels of water soluble tannic acid. Top coats should be applied within 30 days after primer application. Apply in temperatures above 35ºF and below 90ºF. Do not apply in direct sunlight or if surface is hot to touch.  Do not apply if rain is likely to occur.

Dry Time: 1 hour to touch. Allow at least 4 hours dry time before applying top coat. Dry time can be affected by temperature and humidity. Tinting product with universal machine colorants may prolong dry time. Dry time may be prolonged in cooler temperatures.

Coverage: Smooth Surfaces - 400-500 sq. ft. per gallon. Rough Surfaces - 150-250 sq. ft. per gallon. Surface texture, method of application, and wood moisture content will affect coverage.

Tinting: Super Prime may be tinted with up to 4 ounces per gallon with compatible universal machine colorants.

Restrictions: Do not apply if temperature is below 35ºF or if temperature falls below 35ºF for 24 hours after application. Do not apply over wet or damp surfaces. Do not thin this product. Super Prime may not fully prevent extractive bleeding on wood species with an unusually high tannic acid and moisture content. Knots should be sealed with a high quality knot sealer prior to application of primer. For exterior use only.
