External Finishes Types: –Render Render –Tiles Tiles –Weatherboard Weatherboard •Preparation Preparation •Specification Specification •Application Application Again this slide really used as an overview for the following one. Preparation: Block surfaces should be clean of dust, loose particles or contamination before application of finish 40
Finishes - External •Tile Tile hanging or weather boarding – Vapour-permeable membrane should be used •Render Render – Mix to be 1:1:6 or 1:2:9 (C:L:S) – Two coat render • base coat 10-12mm thick • finish coat 6-8mm thick – Joints should be recessed – Blockwork should be cleaned – Blockwork may need to be wetted to balance the initial suction. –Thin Thin coat spray render can be used for Thin-Joint walls Tile Hanging - Tiles should be hung on horizontal battens, with membrane behind Weatherboarding - Hung on vertical battens, with membrane behind Rendering - One of the most common finishes to see not performing properly.(eg cracking). But can be done very successfully - if you get proper advice from Technical Services Dept. Thin coat render 3-4mm can be used on thin joint walls because of greater accuracy of construction 41
