Surface Preparation Sample Clauses
The Surface Preparation clause defines the requirements and standards for preparing surfaces before the application of coatings, finishes, or other treatments. It typically outlines the methods, materials, and conditions necessary to ensure that surfaces are clean, dry, and free from contaminants such as dust, grease, or old paint. For example, it may specify sandblasting, chemical cleaning, or other techniques appropriate for the material involved. The core function of this clause is to ensure that subsequent work adheres properly and achieves the desired durability and appearance, thereby preventing premature failure or defects.

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. 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.

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 ▇▇▇▇▇▇▇ (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. 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. Surfaces shall be clean, dry to the touch, and free from dirt frost, moisture, grease, oil, wax, lacquer, paint, or other foreign matter that would tend to destroy or impair adhesion. Oil and grease shall be removed with solvent and surfaces shall be wiped dry with clean cloths. When resealing an existing joint, remove existing ▇▇▇▇ or sealant prior to applying new sealant. For surface types not listed below, the sealant manufacturer shall be contacted for specific recommendations.
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. Surface preparation is paid for by the square yard (meter) of the concrete surface acceptably repaired and blast cleaned prior to installation of the overlay. Payment includes all expenses associated with removal of existing concrete, repair and blast cleaning operations.
