The surface must be clean, dry and free of all loose dirt, dust, wax, mildew, scaling material, and flaking paint.* Sand glossy surfaces to improve adhesion. Replace loose, cracked or warped boards and repair any damaged areas. Unpainted exterior wood exposed to sun and weather for longer than 2 weeks must be cleaned and sanded prior to priming. On wood species that contain high levels of tannin, like redwood, cedar and fir, 2 coats may be necessary. All mold and mildew must be cleaned with a solution containing one-third-cup heavy-duty laundry detergent, 1 quart household bleach and 3 quarts of warm water. Apply with a scrub brush. Rinse thoroughly and allow it to dry before applying the primer. Do not apply product to bare masonry surfaces subjected to hydrostatic water pressure.
Previously Painted or Stained Wood
Clean previously painted surfaces thoroughly. Remove all loose or flaking paint by scraping. Sand glossy paint surfaces to improve adhesion. Spot-prime areas where the previous coating has peeled or worn away, then prime the entire surface.
Mineral Staining on Previously Painted Surfaces
Mineral staining is caused by naturally-occurring minerals present in the masonry. To control mineral stains that have bled through a surface painted with masonry waterproofer, apply 1 coat of UGL® EcoLok® Primer Sealer over the existing masonry coating. For a uniform appearance, topcoat with an additional coat of a masonry waterproofing paint.
Apply when air and surface temperatures are above 50°F. Apply straight from the can. DO NOT THIN. Apply by brush, roller, or spray. Do not apply to horizontal surfaces if rain is expected within 24 hours. Avoid applying in direct sunlight. Maintain a wet edge to avoid lap marks. If spraying, reduce UGL® EcoLok® Primer Sealer up to 10 percent with clean water. Topcoat with ZAR® Solid Color Deck & Siding Stain or another quality latex or oil-based paint or stain. Heavy stains may require an additional coat.

* WARNING: If you scrape, sand or remove old paint, you may release lead dust. LEAD IS TOXIC. EXPOSURE TO LEAD DUST CAN CAUSE SERIOUS ILLNESS, SUCH AS BRAIN DAMAGE, ESPECIALLY IN CHILDREN. PREGNANT WOMEN SHOULD ALSO AVOID EXPOSURE. Wear a NIOSH-approved respirator to control lead exposure. Clean up carefully with a HEPA vacuum and a wet mop.
