DESCRIPTION

Fermacell Fine Surface Treatment (FST) is a light, ready-to-use surface filler. It achieves a skim plaster type finish in a fraction of the time of conventional plastering methods without the need of specialist skills; allowing the experienced tradesman, self builder or DIY enthusiast to achieve a flawless finish. There is no wet-trade involved to achieve this skim plaster type finish.

Once applied, Fermacell FST gives a smooth surface ready to accept a paint finish. Typically a mist coat and two undiluted top coats are required. Fermacell do not recommend the use of eggshell paint finishes. However, where eggshell paints are used, a minimum of two coats of FST must be applied first, followed by a sealant but users are still advised to refer back to the paint manufacturer’s recommendations.

SURFACE PREPARATION

The surface should be dry and free of stains and dirt. Any damage or indentations must be filled with Fermacell Joint Filler and allowed to dry. Before any decoration, the moisture content of the boards must be less than 1.3%. This moisture content will be achieved automatically within 48 hours if the relative humidity of the air is kept below 70%, the air temperature is over 15°C and the boards are stored off the ground in well ventilated conditions.

APPLICATION

Apply straight from the tub using a trowel or a Fermacell FST applicator. Work on 1-2m² at a time and ensure that the surface is fully covered. Then remove the excess FST in a smoothing out motion using a trowel or a FST applicator. Do not scrape off too hard or too much will be removed. The FST will dry within 45 minutes and subsequent layers can be applied as required. If necessary, smooth the surface with ‘fine 240 grit’ sandpaper, prior to final decoration.
