Render One Skim coat is an off white, cement based, 2 pak polymer modified compound used in the preparation of most surfaces as a leveling and adhesive base coat for selected Render One finishes.

GRADES:

Reg Gauge - For use over even flat substrates

Suitability

• Masonry Block
• Clay Bricks
• Hebel Panels/Blocks
• Cement Sheet
• Cement Panels
• Polystyrene Sheets
• Tiles
• PVC
• Painted Surfaces

Special Features

• Water soluble, easy to clean and environmentally friendly
• Easy to apply and fast to finish
• Superior adhesion eliminating drummyness and delamination
• Can be applied to damp substrates
• Excellent impact and mechanical strengths
• Minimal shrinkage
• Self priming to substrate
• Covers greater imperfections than normal skim coats

Surface Preparation:

All surfaces to be free of oil, dust, loose mortar prior to application

Painted Surfaces

Should be water blasted with a 3000psi pressure cleaner to remove any loose or chalky paint

Render One Skim Coat over painted surfaces should be mixed with a 2:1 water/polymer ratio

Note:The standard manufacturers warranty does not apply to painted surfaces as the original condition of the paint to substrate bond is not usually expected to be known

Mixing Directions:

1. Determine the correct mixing ratio for the Render One Polymer. These vary depending on the substrate.
   • New masonry block four (4) parts water to one (1) part polymer
   • Brickwork four (4) parts water to one (1) part polymer
   • Polystyrene two (2) parts water to one (1) part polymer
   • Steel one (1) part water to one (1) part polymer
   • Cement sheet two (2) parts water to one (1) part polymer
   • Hebel four (4) parts water to one (1) part polymer
   • Painted surfaces two (2) parts water to one (1) part polymer
   • Tiles one (1) part water to one (1) part polymer
   • P.V.C. one (1) part water to one (1) part polymer

   Note: all finishing coats will be mixed with a 4:1 water/polymer ratio

2. Pour approximately four and a half (4.5) litres of the diluted Render One polymer into a clean empty 15 litre pail
3. Gradually add the selected Render One skim coat and mix with a variable speed/high torque mixing drill fitted with a suitable spiral mixer.

   Note: Over mixing of high speed mixing may cause aerating which can affect usability.

4. Mix thoroughly to a workable consistency and apply to substrate using approved application techniques
5. Allow to dry completely before coating with selected Render One finishing coats.

Application Guide

Mix thoroughly to a workable consistency and apply to substrate using hawk and trowel or approved render spray pumps

Remove excess product with trowel in a horizontal motion to achieve a flat, defect free surface suitable for the application of a Render One finishing coat

Drying

Skim coats must be allowed to dry before applying Render One Finishing coats
