TECHNICAL DATASHEET
FEATHER-FLOW FAST
Fast Setting Flowable Feathering Underlay
MULTI FEATHER-FLOW FAST is a fast setting underlay flowable application for a smoothing and feathering screed for a variety of floor coverings. Accelerated cements allow for extended open time and 2 -3 hour walk on applications. For a thicker and smoother build than skimming, MULTI FEATHER-FLOW FAST will flow from 1mm to 10mm and with the same strength and hardness throughout at the same rate of set.
TYPICAL APPLICATION
FEATHER-FLOW FAST provides a hard-wearing non-dusting floor surface over the following interior substrates: Concrete; Masonry and Tiles (using Feather Finish primer).
ADVANTAGES
• Extremely hard surface
• Improved adhesion
• High strength
• Low VOC
• No need for bonding liquids
• No sanding required after installation
• Low dusting when sanded to hard finish
• Fast setting
WATCH POINTS
• Do not re-constitute the mix after initial setting has occurred.
• Do not apply over floors recently heated via underfloor heating. Allow floors to cool before application.
• Colour of the screed surface on setting is not uniform in appearance.
• Do not apply over perpetually damp floors or where moisture is a concern.
• The product sets fast – mix only as much as you can apply with the setting times.
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:
Floors will need to be primed with SCREED PRIMER. Allow for penetration into the substrate and remove any excess pooling of primer. FEATHER-FLOW FAST 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 white primer as this will create runs in the screed and surface discolouration.
Mixing:
Mix 5Lts clean water with 20Kg of FEATHER-FLOW FAST well in a bucket using a mechanical mixer. Pour the water in the bucket first and while mixing add the powder slowly to a lump free, consistent mix.
Application:
Pour over the primed areas and using a steel trowel or pin rake, screed out the product to the desired level or feather as necessary. Ensure as few trowel / pin lines remain as possible, using a spike roller to level stubborn lines while still flowable. Allow to dry and set for 6 - 8 hours before walking back on with any pressure. When moisture levels subside to acceptable levels (24 hours), overlays can be installed directly to the FEATHER-FLOW FAST. 24-hour moisture levels need to be tested for suitability for overlay applications. No sanding required as the surface will be smooth already.
