DIRECTIONS FOR USE

 

SURFACE PREPARATION

Surfaces are to be clean, sound and free of deleterious substances. Remove all laitance, oil, grease, mould oil or curing compound from concrete surfaces using wire brush, bush hammer, scabbler or other plant as appropriate. When repairing damaged concrete, ensure that all loose concrete has removed down to a firm base. Note construction joints that need to be carried through the floor to surface. 

 

PRIMING

Prime porous floors with MULTI SCREED PRIMER. Allow for penetration into the substrate and remove any excess pooling of primer. MULTI FEATHER FINISH can then be applied over the tacky primer or after the primer has been allowed to dry, but no later than 2 hours after drying of the primer. Do not apply over wet pooled primer as this will create runs in the screed and surface discolouration. Sound surfaces need no priming.  

 

MIXING

Mix 2.5L clean water with 10kg of MULTI FEATHER FINISH well in a bucket using a mechanical mixer. Ensure all lumps have been broken up. 

 

APPLICATION

Pour over the primed areas and using a steel trowel, screed out the product to the desired level or feather as necessary. Ensure as few trowel lines remain as possible. Allow to dry and set for 20 minutes before walking back on. Allow 1 hour drying time before use. Sand with 100-120 grit sandpaper to remove high points and polish to a hard, dust free surface prior to overlay installation. 

 

EQUIPMENT CARE

All tools should be cleaned with water immediately after use. If delayed, equipment will need mechanical action to clean or be discarded. 

 

PACKAGING

Supplied in 10kg bags.
