<br />A. General: Surfaces shall be dry and in sound condition. Remove oil, dust, dirt, loose rust, peeling
<br />paint or other contamination to ensure good adhesion.
<br />1. Remove mildew before painting by washing with a solution of 1 part liquid household
<br />bleach and 3 parts of warm water. Apply the solution and scrub the mildewed area. Allow
<br />the solution to remain on the surface for 10 minutes. Rinse thoroughly with clean water and
<br />allow the surface to dry 48 hours before painting. Wear protective glasses or goggles,
<br />waterproof gloves, and protective clothing. Quickly wash off any of the mixture that comes
<br />in contact with your skin. Do not add detergents or ammonia to the bleach/water solution.
<br />2. Remove items including but not limited to thermostats, electrical outlets, switch covers and
<br />similar items prior to painting. After completing painting operations in each space or area,
<br />reinstall items removed using workers skilled in the trades involved.
<br />3. No exterior painting should be done immediately after a rain, during foggy weather, when
<br />rain is predicted, or when the temperature is below 50 degrees F (10 degrees C), unless
<br />products are designed specifically for these conditions. On large expanses of metal siding,
<br />the air, surface and material temperatures must be 50 degrees F (10 degrees F) or higher to
<br />use low temperature products.
<br />B. Aluminum: Remove all oil, grease, dirt, oxide and other foreign material by cleaning per
<br />SSPC-SP1, Solvent Cleaning.
<br />C. Block (Cinder and Concrete): Remove all loose mortar and foreign material. Surface must be free
<br />of laitance, concrete dust, dirt, form release agents, moisture curing membranes, loose cement,
<br />and hardeners. Concrete and mortar must be cured at least 30 days at 75 degrees F (24 degrees C).
<br />The pH of the surface should be between 6 and 9, unless the products are designed to be used in
<br />high pH environments. On tilt -up and poured -in-place concrete, commercial detergents and
<br />abrasive blasting may be necessary to prepare the surface. Fill bug holes, air pockets, and other
<br />voids with a cement patching compound.
<br />D. Concrete, SSPC-SP13 or NACE 6: This standard gives requirements for surface preparation of
<br />concrete by mechanical, chemical, or thermal methods prior to the application of bonded
<br />protective coating or lining systems. The requirements of this standard are applicable to all types
<br />of cementitious surfaces including cast -in-place concrete floors and walls, precast slabs, masonry
<br />walls, and shotcrete surfaces. An acceptable prepared concrete surface should be free of
<br />contaminants, laitance, loosely adhering concrete, and dust, and should provide a sound, uniform
<br />substrate suitable for the application of protective coating or lining systems.
<br />E. Cement Composition Siding/Panels: Remove all surface contamination by washing with an
<br />appropriate cleaner, rinse thoroughly and allow to dry. Existing peeled or checked paint should
<br />be scraped and sanded to a sound surface. Pressure clean, if needed, with a minimum of 2100 psi
<br />pressure to remove all dirt, dust, grease, oil, loose particles, laitance, foreign material, and
<br />peeling or defective coatings. Allow the surface to dry thoroughly. The pH of the surface should
<br />be between 6 and 9, unless the products are designed to be used in high pH environments.
<br />F. Copper and Stainless Steel: Remove all oil, grease, dirt, oxide and other foreign material by
<br />cleaning per SSPC-SP 2, Hand Tool Cleaning.
<br />G. Exterior Composition Board (Hardboard): Some composition boards may exude a waxy material
<br />that must be removed with a solvent prior to coating. Whether factory primed or unprimed,
<br />exterior composition board siding (hardboard) must be cleaned thoroughly and primed with an
<br />alkyd primer.
