Equipment Cleaner: Crown White Spirits.
Availability: From Crown Depots in Nairobi, Mombasa and Kisumu or through Crown Stockists.
Surface Preparation: Remove all dust, grease and lose material from the rebate. Any moisture on the timber should be wiped off using a clean paper towel or other absorbent material to give a dry surface.
Application: Check the condition of the primer or stain on softwood timber frames, especially the rebate and glazing surface of the beads. Any section which has been partially missed or is considerably weathered should be reprimed before glazing. Rebates of hardwood frames which are to be protected with clear varnish should be sealed with a sealer. Location blocks should be used inside hung opening windows to hold the glass in place.
When using as back bedding, apply to rebate. Push in glass and leave a thickness of 1.5mm by 2mm so as to achieve sufficient load bearing properties. The maximum fillet size to allow correct setting is 15mm high x 25mm wide. Do not reduce the fillet size below 8mm high x 10mm wide.
Finishing: The putty must be painted as soon as it has formed a skin firm enough to accept the actions of overcoating. Apply the first coat usually within 7 – 21 days. The final coat should be applied within 28days.
Health & Safety: Keep out of the reach of children. Wash hands after use. Safety data sheet available for professional user on request. Dispose of empty packaging in accordance with regulations.
