Terrix® PL-FS-S
spray plaster coat
fast set
Terrix® PL-FS-S is a plaster that has been formulated for machine application on wall and ceiling surfaces inside buildings. It has been specifically recommended as a substitute for traditional internal plasters and skim coats. The smooth white colour and surface texture of Terrix® PL-FS-S allow for a reduction in the quantity of paint required to achieve a full decorative effect. The product is available in an easy-to-apply compound form that can be sanded quickly after hardening.
Terrix® PL-FS-S is a versatile product that can be applied to all types of mineral substrates, including concrete, cement renders, cement-lime renders, lime renders, skim coats, and drywall. It dries faster and offers higher bonding than PL-SX-S, making it a suitable option for boards with low surface absorbency and application during winter/wet months. This product is an ideal choice for those seeking a reliable and efficient solution for plastering both residential and commercial buildings.

*Usage conditions:
The product can be used or applied in higher humidity levels; however, it is crucial to ensure that the product is not exposed to high humidity or condensation for repeated or prolonged periods in order to maintain its optimal strength and adhesion.
When applied in temperatures between 5-10°C, the product’s drying time may be extended, and its performance can be influenced by factors such as humidity and ventilation.
Consider these environmental conditions during application and drying to achieve the best results.
CAUTION: Keep the product out of reach of children.
Application
Substrate preparation:
Apply to a sound, clean substrate (without cracks and delaminations), degreased, even, dry, and biological or chemical efflorescence-free. The substrate should be free of algae/fungi growth.
In case of microbial contamination, the substrate should be cleaned with a power washer. Subsequently, a biocide solution for removing microbial contamination is to be applied as per the product manual. Any loose layers not bound to the substrate (such as loose plasters or flaked paint coats) should be removed. Wash and degrease old and dirty substrate with water and a cleaning agent. Existing holes, unevennesses and cracks should be filled according to the best construction practices. Substrates covered with well-set dispersion coating should be sanded and dedusted before the product application.
Note: if the product is applied on newly completed mineral substrates (i.e. cement-lime renders, cement-renders and concrete substrates) — min. a 2-week curing period is required.
Priming:
Absorbent substrates should be primed with Terrix® PR-UA before spray plaster application.
Product preparation:
Product intended for direct use — do not dilute. Before application, the product should be thoroughly mixed.
Application method:
Apply a thin, uniform product layer on the substrate at a thickness from film to 2 mm using a spraying machine (airless method). In order to do it, special tools intended for applying spray plasters should be used (e.g. T-MAX by GRACO ), as well as suitable powerful devices for paint application (e.g. MARK V by GRACO or SPEEFLO PT6900 XLT DI by WAGNER). While spraying, the gun should be directed perpendicularly towards the substrate at a distance of ca. 1.0÷1.2 m (T-Max GRACO) and ca. 0.5÷0.6 m (Mark V GRACO)
If more significant unevenness is present, the material should be applied in a few layers after the previous layer hardens. After the surface dries, it may be sanded.
To be applied on days with temperatures (air and substrate) between 5-25°C. All tools are to be cleaned with water after finishing work.
Sanding:
Use orbital sanders with an extractor. Recommended sandpaper- 180-220.
Drying:
The product applied on the substrate can be subject to further processing after approx. 12 hours (20°C, 55% RH). Substrate water absorption, coat thickness and air circulation in the room may significantly affect the drying time of the product.
