Plaster application tools:
- plastic container for mixing with at least a 65-litre capacity
- electric mortar mixer with approx. 500 rpm, or a forced action mixer (e.g. Filamos M series)
- stainless steel finishing trowel and notch trowel
- plastic float, sponge float (stiff)
- bricklayer lath and spirit level
Preparation of plaster mixtures
Compliance with the following points is very important for the quality and workability of plaster. Strictly follow these rules:
- always use a whole pack
- plaster mixing procedure is specified on the packet
- follow the specified water dosage (may vary depending on weather conditions)
- stirring time of 5-7 minutes
- leave plaster to sit for 5 minutes
- stir again for 1 minute
- first, apply a layer 5-8 mm thick
- after 4-6 hours, apply another 15-20 mm layer
- strip plaster with bricklayer’s lath
- finally, apply the final plaster in 5-8 mm layer and turn it using a float – this operation must be performed on the entire wall in one go (from corner to corner) to avoid making connections to already set plaster, i.e. it is the same procedure as when applying paste plaster e.g. on a thermal insulating system.
For the application of our products, we recommend using corner strips and applying plaster to screeds once corner strips have been installed. Plastic screeds can be left in the plaster and during the final step can be covered with at least 6 mm of plaster. If you use screeds which will be removed, do not forget to thoroughly fill the resulting grooves to avoid risk of cracking. For increased performance of your plasterwork, various system components manufactured for CIS (Contact Insulating System) (aluminum battens, window stop beads, expansion strips, plaster stops etc.) can be conveniently used. Always keep in mind that when connecting Satsys plaster to other materials (plastics, metal, and wood), an expansion joint must be made – either using a polyurethane sealant (the minimum requirement) or more preferably by installing an expansion strip.
If the surface of the Satsys plaster facade is going to be painted, our sales representatives will recommend a suitable coating that does not impair the functional properties of the plaster, in particular its diffusion resistance. We recommend paints based on silicate or silicone and for historic buildings also lime-based paints. The plaster can be painted after just 48 hours!
