Surface Preparation. Clean the surface to be treated of all dust, dirt, clay, grass, sod and any other deleterious matter before application of the asphalt surface treatment.
Surface Preparation. 1. The Contractor shall examine the areas and conditions under which work will be performed. The Contractor shall ensure that each surface is cleaned and prepared as required for proper adhesion.
2. The Contractor shall correct conditions detrimental to timely and proper completion of the work, to include but not limited to the repair of minor holes, cracks, chips, rips, dings, etc. Should any surface be found unsuitable to produce a proper paint or sealant finish, the Contractor shall notify the County’s Service Coordinator in writing and no painting products shall be applied until the unsuitable surfaces have been approved as satisfactory.
3. For proper adhesion, the Contractor shall ensure that all surfaces to be coated are cleaned and free from rust, dirt, mildew, mold, algae, grease, oil, peeling and/or loose paint, powdery chalky residues and any other material or condition that may inhibit bonding and adhesion. Deterioration shall be removed with a combination of solvent or detergent washing, hand or power tool cleaning, to bring back to an acceptable surface. Glossy areas of sound previous coating need not be removed but should be mechanically abraded or chemically treated to create a surface profile that increases coating adhesion.
4. The Contractor shall pressure clean exterior surfaces according to the pressure cleaning specification below where needed. Should old coatings begin to peel off, the Contractor shall use additional removal techniques to achieve a solid substrate including higher pressure washing, scraping, and wire brushing or ultimately, wet or dry sand blasting may be needed.
5. On some buildings where elastomeric coatings were previously used, tests shall be made with a scraper to assure proper adhesion. If proper surface preparation underneath the elastomeric coating was not properly done, the elastomeric shall be peeled off with at least 3000 psi and with hand methods as necessary.
6. The Contractor shall verify that all substrate conditions are ready to receive work prior to application of any painting products (primer, finish coats, etc.)
7. The Contractor shall remove or mask electrical plates, nomenclature plates, hardware, trim or fittings prior to preparing surfaces or finishing. The Contractor shall ensure that all items removed are replaced to their original condition or better, prior to completion of the job.
8. Rust Removal

Surface Preparation. Immediately before marking the pavement surface, clean the surface of dirt, oil, grease, and foreign material, including curing compound on new concrete. Clean the surface 2 inches beyond the perimeter of the marking to be placed.
Surface Preparation. Coating Application
Surface Preparation. Use biodegradable soaps, cleaners and teak cleaners approved for ocean waters.
Surface Preparation i. Use biodegradable soaps, cleaners and teak cleaners approved for ocean waters.
ii. Liberally use tarps to capture all scrapings, debris and drips. No material may enter the water.
iii. Only vibrator xxxxxxx (maximum of 2) with vacuum capture is allowed in the slips.
iv. Use a vacuum to remove all dust and debris. No material may enter the water.
Surface Preparation. 4.1 In general, all structural and miscellaneous steel, including enclosures, inlet ductwork, exposed piping and carbon steel exposed to inlet air shall be cleaned prior to coating in accordance with SSPC-SP 6 or SSPC- SP 10. Refer to Table 1 for specific requirements. The blast profile shall be 1-2 mils as measured with a Xxxxx-Xxxxx Surface Profile Comparator or equivalent. A surface profile tape can also be used to measure surface profile. (Press-O-Film tape developed by TESTEX, Inc. is an example; equivalents are also acceptable.)
Surface Preparation. A. Remove all existing bituminous material that is unstable or non adherent to the pavement.
B. Thoroughly clean the surface of the patch to remove dust and debris just prior to ACC placement.
Surface Preparation. Correct defects and inaccuracies in roof deck surface to eliminate poor drainage and hollow or low spots and perform the following:
Surface Preparation. Manufacturer's standard practice for surface preparation of interior and exterior surfaces shall be used. The interior of piping and pressure vessels shall be free from dirt and debris. Exterior surfaces shall be coated in accordance with the Manufacturer's standard practice.
