Overview

KingRep 5 is a one component acrylic polymer modified powder. When mixed with water KingRep 5 produces a highly consistent, smooth, fine, trowel able mortar.

Applications

For fair face concrete repair
As a thin layer render
As a skim coat for pin holes and minor honeycombed concrete repair
As pore sealer and leveling mortar
To produce a uniform surface for subsequent paint finish

Advantages

Shrinkage controlled polymer modified cementitious repair mortar which reduces any potential cracking
Easy to apply, single component which requires only addition of water
Excellent adhesion to concrete, no independent primer or curing is required
Compatible with other types of protective coatings
Can be applied to feather edge thicknesses
Suitable for internal and external applications
Cost effective, hand applied no formwork is required

Note	Declared results above are for the grey colour. The powder is then added slowly to the water while mixing continuously with low speed mixer/drill (400 - 600 rpm). Mixing time should be continued for 3 minutes until uniform consistency is obtained. To enhance the scratch resistance of KingRep 5, an addition of KingBond SBR is advisable. 50% of the total mixing water shall be replaced by KingBond SBR range. PLACING AND FINISHING KingRep 5 can be applied by steel trowel. The mixed mortar can be applied to the prepared substrates at up to 3 mm thicknesses. The applied mortar should be allowed to stiffen before trowelling to a smoother finish.	—
