*Usage conditions:
The product can be used or applied in higher humidity levels; however, ensuring that it is not exposed to high humidity or condensation for repeated or prolonged periods to maintain its optimal strength and adhesion is crucial. 
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 delamination), degreased, 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/or 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:
Before plaster application, absorbent substrates should be primed with Terrix® PR-UA (mixed with water 1:1).

Product preparation:
Product intended for direct use — do not dilute. Before application, the product should be thoroughly mixed.

Application method:
Apply the levelling compound in a thin and even layer between 1 mm and 3 mm with a stainless steel trowel. If more significant unevenness is present, the material should be applied in a few layers after the previous layer hardens. If used as a joint filler, a jointing tape or scrim has to be used. After the surface dries, it may be sanded.

Sanding:
Use orbital sanders with an extractor. Recommended sandpaper- 180-220. Small areas can be hand sanded.
Drying:
The product applied on the substrate can be subject to further processing after ca. 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.
Useful hints:
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.
