Epoxy Blast Primer

Surface Preparation:           

Apply to blast cleaned steel only : minimum standard of cleanliness Sa 2.5 Swedish Standard SIS 05.59.00 or Second Quality BS4232 : 1967. For highly corrosive conditions specify SA 3/First Quality. We recommend abrasive no larger than S.240 or G24 so that surface profile dose not exceed 100 microns. Steel which has been weathered for several months previously can retain significant amounts of corrosion stimulating salts after blasting and special care is required in preparation.

Application:

Stir Part A thoroughly and then add Part B : continue stirring until, thoroughly mixed. Royale Epoxy Blast Primer is normally used as a pre-fabrication Primer where steel processing will allow for a faster dry to handle time.

Pre-fabrication : apply 25-30 micron dry thickness. Use airless spray tip size of  0.38-0.48mm (0.015.0.19 in) : tip pressure 110-160 kg/cm2 (2100-2300 lb/in2). For conventional spray use any standard equipment at a pressure of 2.8.3.0 kg/cm2 (40-45lbin2. No thinning should be necessary . Apply a full wet coat of paint to prevent porosity from dry spray. Hold airless gun about 12 inches from steel surface. Hold conventional gun approximately 8 inches from surface.

We recommend that all welds should be ground or vacuum blasted to remove weld slag and spatter etc. Bare areas should be patched-primed with Epoxy blast Primer. Apply Further coating as specified.

Post-fabrication : Apply 50-60 microns dry thickness. Apply further coating as specified.

Overcoating:

May be overcoating with single-pack or two-pack products (see “Drying Time”).Royale Epoxy Blast Primer dose not form surface salts on weathering but steel will become dirty during transport, storage and erection. Remove site debris and other contaminants with a stiff brush and fresh water. Clean off oil/grease with Solvent and rinse with fresh water.

Thoroughly wire-brush damaged areas and touch-up with Epoxy Blast Primer. Apply further coating as specified.

 

Epoxy Coalter - 200

Surface Preparation:

Steelwork : Apply to blast cleaned steel only : minimum standard of cleanliness Sa 2.5 Swedish Standard SIS 05.59.00 or Second Quality BS4232 : 1967. For highly aggressive conditions specify SA 3 or “First Quality”. We recommend abrasive size no larger than S.240 or G24 so that surface profile is not likely to exceed 100 microns. Steel which has been weathered for several months prior to blasting can retain significant amounts of corrosion stimulating salts and special care is required in preparation.

Epoxy Coalter-200 may be applied directly to blast cleaned steel. In circumstance where a holding primer is necessary, Epoxy Coalter-200 can be used over Royale Epoxy Enamel or Royale Epoxy Primer or Royale Epoxy Clear.

Galvanizing: Degrease with thinner 180/15: abrade lightly. Ensure that the surface is clean. Treat with Royale Two-pack  Wash Primer.

Metal Spray: this should be coated as soon as possible before the porous surface absorbs contaminants. Epoxy Coalter may be applied direct to the surface providing the first coat is thinned to assist penetration. Metal spray already pre-sealed with other materials may require a compatibility test.

Aluminum: Degrease and abrade with Royale Epoxy thinner and wet-or-dry paper .Apply Royale Epoxy Primer or Royale Two-pack  Wash Primer.

Concrete: Ensure that the surface is sound. Remove laitance by thorough wire brushing, acid etching or sweep blasting blowhole and other defects should be filled. Royale Epoxy Coalter-200 may be applied direct to the clean sound concrete providing the first coat is thinned (see Application).

Application:

Stir part A vigorously and add Part B : continue stirring until thoroughly mixed. First coat application on metal spray or concrete should be thinned up to 20% by volume with 180/15 to assist penetration.

Use airless spray tip/nozzle size .48-058mm (0.019-0.023 in) : tip pressure 110- 160 kg/cm2 (1600 -2300 lb/in2).

Apply a full wet coat, holding the gun 12 – 15 inches from the surface being painted. With brush or roller application care is necessary to achieve the necessary wet film thickness.

Apply at least two coat, one coat Chocolate and one of Black, to a minimum total dry film thickness of 250 microns. 

Epoxy  Enamel

Preparation – Priming – steelwork:

The surface to the clean, dry, free from rust and millscale. Girt or shot-blasting is recommended to Swedish Standard Sa 2.5 or Second Quality BS4232 minimum. Surface profile not to exceed 100 microns. Where highly corrosive conditions exist. First Quality blasting should be specified. Millscale must be removed for optimum performance, hand or mechanical cleaning is not effective.

The blast cleaned steel to be primed within 4 hours Royale Epoxy Enamel or Royale Epoxy primer.

Galvanized steel. Aluminum, copper, brass, zinc sprayed steel, to be degreases, abraded where appropriate to form key, and then pretreated with wash primer followed with Royale Epoxy primer.

Finishing  :-     Three coat enamel to shade, overcoating drying between coats.

Wood – Plywood etc :

Sandpaper, dust down, fill up holes, cracks, etc. Apply one coat Royale Epoxy Primer White and three coat enamel to shade.

Floors – Furniture : Clear Finish : Sandpaper, dust down then apply two or three coat Royale Epoxy clear, thinning first coat approximately 10% with Royale Epoxy thinner per gallon. Over night drying between coats.

Concrete – Plaster – Brick – Asbestos:

Sandpaper, dust down to remove cement splashes etc. Fill up holes and cracks. Apply three coat enamel, thinning first coat 10% with Royale Epoxy thinner per gallon.

Epoxy high Build (self Leveling)

Surface Preparation:

Steelwork: Apply to blast cleaned steel only : minimum standard of cleanliness Sa 2.5 Swedish Standard SIS 05.59.00 or Second Quality BS4232 : 1967. For highly aggressive conditions specify SA 3 or “First Quality”. We recommend abrasive size no larger than S.240 or G24 so that surface profile is not likely to exceed 100 microns.

Hold airless spray gun at approximately 12  inch from the surface being painted. Hold conventional spray gun approximately 8 inch from surface.

We recommend that all welds should be ground or vacuum blasted to remove weld slag and spatter etc. Bare areas should be patch primed with Royale Epoxy Zinc Rich Primer. Apply further coating as specified.

Post-fabrication : apply 50 microns minimum dry thickness followed by further coating as specified.

Overcoating:

May be ovecoating with single pack or two pack product (see ”Drying Time”). Royale Epoxy Zinc Rich Primer may from surface salts on atmospheric exposure. These must be removed prior to overcoating : use a stiff bristle brush with fresh water. Site debris and other dry contaminants may be removed in similar fashion. Oil and grease should be removed with solvent, followed by a fresh water rinse. Allow to dry before further painting. Thoroughly wire brush damage areas and touch-up with Royale Epoxy Zinc Rich Primer. Apply further coating as specified.
