Methods of application:
Instructions for use:
Prior to application, the compound shall be diluted, as needed, with water with regard to the use required.
Banding of joints with a paper band: the compound shall be diluted (approx. 1dl of water per each kg of the compound). Generally, the compound shall be as thin as possible so that it adheres to the paper band properly (by absorbing), and the occurrence of air bubbles is prevented. The compound should not drip from tools!
Note: when stirring the compound, do not use stirrers that create whirls as they draw air bubbles in the mass! This causes problems in further application.
Apply sufficient layer of the compound to the plasterboard panel joint by a joint knife or a special binding tool (application by means of special tools substantially speeds up the work). Press the paper band in the compound applied by means of a joint knife. Excessive compound or air shall be pushed out from under the tape by a joint knife. The joint shall be as smooth as possible in order to avoid unnecessary grinding. The joint prepared in this way shall completely dry up! The period of drying depends on the thickness of the layer applied and the ambient temperature ranging from 5 to 24 hours. Due to water evaporating from the compound the mass under the tape will lose 3-5 % of the thickness. After complete drying, the joint can be further treated by grinding and applying the first layer. The layer shall be spread more in width so that "invisible joint" is achieved.
Final binding/ levelling: After drying up and grinding of the first layer, the second- "final" layer 0.3-1mm thick shall be applied by stainless steel trowel all over the area. For such levelling, it is sufficient to dilute the compound with water (approx. 0,5 dl of water per each kg of the compound). Upon drying up, roughness can be removed by grinding.
The use of Versatile Joint Compound for reconstructions: Prior to application, old coatings, loose layers of old plaster and dust shall be removed from the surface, and primer shall be applied. Final layers/filler can be applied in a classical way - by a stainless steel trowel, up to 3 mm in thickness, creating a smooth surface that is treated by grinding upon drying up. Surfaces can be textured by various types of rollers. The surface texture resulting depends on the roller type and the paste dilution ratio. Generally, thicker compound and a roller with long hair create rough and coarse surface texture. Thinner compound and a roller with short hair create finer and thinner surface texture.
Use protective aids: Gloves, a respirator (when grinding), goggles
Storage: 12 months at the temperatures between +5°C and +30°C in a dark and dry place. Do not expose to direct sunshine! Protect from freezing!
