CONTENTS CONCRETE REPAIR CORROSION CONTROL GROUTS & ANCHORS PROTECTIVE COATINGS INDUSTRIAL FLOORING SURFACE TREATMENTS JOINT SEALANTS CONCRETE JOINTING ROOFING WATERSTOPS WATERPROOFING JOINT FILLERS TIMBER FLOORING ALPHABETICAL Enamel / Oil Based: Depends on underlying substrate. For steel, abrade and apply Emer-Gard Primer Type 2. Other substrates refer to your local Parchem sales office. Timber surfaces: Treat previously painted surfaces as above. Prime: One coat of Emer-Acrylic Sealer. Note: do not apply Emer-Acrylic Sealer over old oil based paints. Powdery Paintwork or Absorbent Masonry Surfaces: Should be sealed with one coat of Emer-Coat Clear Sealer. Overcoating old Emer-Clad / Impact: Clean the surface with mild detergent, rinse with clean 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. Movement joints All expansion and movement joints should be sealed with a suitable sealant. Ideally, Emer-Impact should not be applied over movement joints as the amount of movement may be more than the capacity of the coating. Joints should be first sealed with the appropriate joint sealant then the Emer-Impact applied up to the edge of the joint. When this is not practical, all movement joints should be sealed with Emer-Seal MS. Polyurethane sealants should be avoided as they can bleed plasticisers into the coating above. Consult your local Parchem sales office for advice on the method best suited to your application. Application Emer-Impact may be applied by a variety of rollers to achieve a number of different texture finishes. Application by Rolana or long nap roller at 5 m²/litre/coat. Application by Roma or texture roller at 1.5 m²/litre/coat. Note: these figures may slightly vary depending on the substrate. Application on top of textured finishes including Emer-Impact Roma - 1 coat at 5 m²/litre. INDEX 194 Spary Application When being applied to well prepared surfaces (no blow holes) it is possible to spray apply Emer-Impact in a single coat to achieve the 170 micron dry film thickness (360 micron wet film thickness). This can be a substantial time saving on a project. Suitable equipment includes Graco 795 or Graco 1095 airless running at 2800 psi and utilising 19 thou or 21 thou spray tips. For further information contact Parchem. To visually facilitate coverage and ensure adequate film build, different colours may be used for each coat of Emer-Impact. Note: do not apply any materials during damp or rainy conditions or where there is likelihood of rain. Temperatures above 30°C reduce the wet edge time and, as with other water based coatings, may increase the risk of showing lapmarks and rollermarks after drying, especially with darker colours. Dark colours may show slight oxidisation over time. This will not affect the performance of the coating. This can be removed temporarily by cleaning, Cleaning Tools and equipment should be cleaned with water immediately after use. Note: As with all specialty coatings we recommend that the application be carried out by an applicator who is skilled in the procedures and techniques necessary to achieve the desired finish.
