The coverage figures are theoretical - due to wastage factors and the variety and nature of possible substrates, practical coverage figures may vary accordingly. Maintenance No special requirements, any damage identified during normal inspections should be repaired or replaced as appropriate. Specification Clauses Decorative waterproofing facade coating The decorative waterproofing coating shall comprise a suitable primer system overcoated with Emer-Impact, 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 180 microns and shall be capable of providing carbon dioxide diffusion resistance equivalent to not less than 50 metres of air. Application Instructions Surface preparation All surfaces to be coated are to be clean, sound and dry, free of mould release agents, bond breaking coatings, curing compounds or any contamination that may affect the coating. New concrete and rendered surfaces to be allowed to cure thoroughly before application of materials. Concrete surfaces should be smooth, any imperfections, pinholes etc. to be filled and surfaces made smooth with Emer-Patch (smooth) and trowelled to an even finish. Moss or lichen should be removed physically, and the surface then treated with a solution of household bleach (1 part bleach to 2 - 3 parts water) to kill any spores. The bleach solution to be allowed to react for 10 - 15 minutes and then be completely removed with clean water and the surface allowed to dry. Priming Parchem manufacture a range of primer/sealer coatings for use with the Emer range of protective and decorative coatings. Concrete, Render, Brick, Masonry, Fibre Cement Panels: Thoroughly clean 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 cracks and joints with acrylic gap filler. 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-Impact. Adhesion testing is advisable. Oxidised surfaces and other contaminations should first be removed with Emer-Clean etch solution. Emer-Coat Special Primer may be used to further increase protection. Sound, Previously Painted or Primed Surfaces: Acrylic: On existing sound acrylic coatings, scrub with detergent and water, allow to dry. No primer required. If coatings are delaminating then remove all loose and flaky paint back to a sound firmly adhered edge then apply one coat of Emer-Coat Clear Sealer.
