MULTI FEATHER FLOW LITE

Description

MULTI FEATHER FLOW LITE is a general-purpose underlay flowable application for a smoothing and feathering screed for a variety of floor coverings. Ordinary Portland cement allows for extended open time and next day walk on applications. For a thicker and smoother build than skimming, MULTI FEATHER FLOW LITE will flow from 1mm to 10mm and with the same strength and hardness throughout at the same rate of set.

Typical Applications

MULTI FEATHER FLOW LITE provides a hard-wearing nondusting floor surface over the following interior substrates:

• Concrete
• Masonry
• Tiles (using Feather Finish primer)

Advantages

• Extremely hard surface
• Improved adhesion
• Next day walk on
• Low VOC
• Ease of application
• No sanding required after screeding

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 damp floors or where moisture is a concern.
• Thicker screeds will take longer for moisture to escape for overlay applications.

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 MULTI SCREED PRIMER. Allow for penetration into the substrate and remove any excess pooling of primer. MULTI FEATHER FLOW LITE 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.

Mixing:

Mix 5Lts clean water with 20Kg of MULTI FEATHER FLOW LITE 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 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 8 hours before walking back on with any pressure. When moisture levels subside to acceptable levels (24 hours min), overlays can be installed directly to the MULTI FEATHER FLOW LITE. 24 hours moisture levels need to be verified with a moisture meter before overlaying. No sanding required as the surface will be smooth already.

Equipment Care:

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

Packing
