Good preparation is essential. Surfaces must be firm, dry, clean and free from dust and loose, flaking, friable materials and substances that may diminish adhesion.

Smooth surfaces should be roughened before applying SF-Spray Finish skim coat putty. Old paint layers should be removed up to the cement plaster.

If the substrate is too dry for spray application moisten it before spraying.

1. 1.First, get the required amount of clean water in to a cleaned container & gradually add 20 kg of SF-Sprayable Skim coat powder while mixing for 6-8 min. Allow to stand mixture 5 minutes after 1st mixing, and then do the 2nd mixing until lumps free creamy paste is obtained,
2. For hand application, add 7-8 kg of water, for spray application add 7.5kg to 9 kg of water(or adjust the viscosity of slurry as required)
3. A pumping machine is use for the pumping and spraying of slurry
4. Spray plaster with thickness of 1-3 mm in one coat. To mix the SF - Skim Coat, use a proper mixing instrument, otherwise you will not get a high-quality mixture

Apply evenly to substrate with a steel trowel or putty knife up to 1-2mm thick per coat.
Or can spray using a putty spraying machine, 1-3 mm thick per coat. For spray application adjust the viscosity by adding water as required. The recoat could be after the first coat is fully dried or after 12 hrs (the drying time will depend on humidity). The prepared mixture should be applied within 60-90 min. To get a smooth surface, use #180 or finer sandpaper.

Drying and curing of the product is affected by type, dryness and porosity of the surface, temperature, humidity, ventilation, climate conditions and application technique and therefore drying and curing specifications can only give as a guide. At 28 0 C, to set 60-90 Min This is a guide only (refer to information above) Do not add water into the cured putty and reuse it.

Store in a dry place. Protect from moisture and bag damage. Available in 20 kg paper bags.

The use of gloves, mask and goggles is recommended.
Clean the instruments properly with water just after the application finish

Do not apply in wet conditions or if rain is imminent or if temperatures go beyond the range of 5^oC and 45^oC.
