Specification Clauses Decorative waterproofing facade coating The decorative waterproofing coating shall comprise a suitable primer system (if required), overcoated with Emer- Clad Matt/Satin, single-component elastomeric coating suitable for application by brush, roller or spray. The total dry film thickness of the coating shall be not less than 250 microns and shall be capable of providing carbon dioxide diffusion resistance equivalent to not less than 250 metres of air. It must exhibit a water vapour transmission resistance Sd not more than 1.0 metres. Application Instructions Surface preparation Concrete, Render, Brick, Masonry, Fibre Cement Panels: Thoroughly clean down surfaces by stiff brush, scraper, etc., to remove all laitence, dirt, dust or other contamination to leave sound, clean, dry surfaces free from all residues. Use Emer-Patch Smooth patching compound to fill minor cracks or level the surface. Fill “non-moving” cracks and joints with acrylic gap filler. Moving joints should be sealed with Emer-Seal MS. Do not use polyurethane based sealants. Prime: One coat of Emer-Acrylic Sealer or Emer-Coat Clear Sealer. Damp Surfaces - Entrapped Moisture: Seek technical advice from Parchem. Mould infested surfaces: Scrape or clean thoroughly; all finishes lifting or badly infested should be removed. Wash down with a watersoluble fungicide or one part domestic bleach to eight parts water, scrubbed into the affected area, then rinsed clean of residues. Make good any defects and allow walls and repairs to completely dry. Prime: One coat of appropriate primer depending on substrate. Iron or Steel: Grease or oil to be removed with degreasing solution. Wire brush/shot or sand blast metal. All dust/dirt to be removed. Prime: One coat of Emer-Gard Primer Type 2. Note: failure to properly coat the metal with primer will result in surface staining and/or significantly diminish the protection of the iron or steel. Rusty Iron or Steel: Remove loose rust and paint particles with wire brushing. Sound areas of remaining paint should be roughened to obtain a good mechanical key. Loose flakes or corroded metal must be chipped away. 1st Coat: One coat of Emer-Tan rust converter Prime: One coat of Emer-Gard Primer Type 2 Aluminium/Zinc/Copper/Brass/Galvanised Iron: A suitable metal etch solution to suit acrylic coatings may be required prior to priming with Emer-Bond Primer and application of Emer-Clad. Adhesion testing is advisable. Sound, Previously Painted or Primed Surfaces: Acrylic: On existing sound acrylic coatings, scrub with detergent and water, allow to dry. No primer required.
