3.1.3 Painting must not take place when the surface temperature is less than 3ºC above the surrounding air’s dew point, when the air relative humidity is higher than 85%, and when the temperature is below 5 ºC.
3.1.4 Prior to any application, the surface must be stable, firm, dry, and free of dust and concrete laitance. The surface must have no cracks.
3.2. Scaffolding and working at heights
3.2.1. Please refer to WMS for Scaffolding Installation.
3.3. Preparation of Coating Materials
3.3.1. All coating materials shall be thoroughly stirred in a container. Only approved thinners shall be used. Mixing shall be carried out in a well-ventilated area. See the painting product data and specification sheet for the mixing ratio.
3.3.2. During Mixing and Painting Application, an appropriate mask shall be worn in accordance with the recommendation of the approved MSDS.
3.3.3. MSDS shall be available at the site and made known to workers.
3.4. Coating
3.4.1. Each coat shall be applied uniformly over the entire surface. Any imbalance surface shall be prepared by filling up using an approved Acrylic Filler, then apply to sand when dry and apply recoat. On beams, columns, and irregular surfaces, edges shall be coated with the recommended paint first and an additional pass made later.
3.4.2. Each coat shall be allowed to dry for the time specified by approval before application of any succeeding coat. See the product painting material/substances SDS and details also to verify Applicable Rate (AP) and Dry Film Thickness.
3.4.3. Any primer coat exposed to excess humidity or rain before drying shall be permitted to dry and the damaged area of primer should be removed to the bare substrate.
3.4.4. Dust and lose particles shall be removed by using sanding till the surface is dry, sound, and wiped clean. Re-practice using the same primer and while dry practice paint filler to check for flat and clean surfaces. When the surface is ready to receive the topcoat then carried out the specified coating to satisfy DFT and specs.
3.4.5. Dust and loose particles shall be removed by sanding until the surface is dry, sound, and cleaned. Re-apply using the same primer and when dry apply paint filler to check for flat and smooth surfaces. When the surface is ready to receive the topcoat then applied the required coating to meet DFT and specifications.
3.4.6. The time interval between applications of two (2) successive coats must not exceed that specified by the product. Any coating shall be cleaned and freed from spray dust before the following coat is carried out.
