Instructions for the application of mica plaster Starlight

To process Starlight

Subsoil:

Mica plaster-Starlight can be applied directly to lime-cement, gypsum-cement plaster and similar mineral substrates. On plasterboard, MDF, glass, galvanized sheet metal and surfaces painted with dispersion paint, prime once with the adhesive primer. For the clay plaster, a lime slurry should be rubbed in or additives such as marble or lime grit are already mixed into the clay plaster.

1st application:

Mix the marble lime plaster well and add up to 0.4 lt. of water if necessary. Apply with an INOX smoothing trowel without pressure. Small trowel strokes are permitted; they are scraped off later. This is better than already compressing too much. The layer must cover the substrate, but should not be much more than the grain thickness, i.e. approx. 0.5 mm. This layer has a drying time of at least 12 hours.

2nd application:

If desired, colour the putty (instructions) and apply with a Venetian smoothing trowel using little material and moderate pressure. Allow to tighten a little and press with increasing pressure and without material. The resulting lime sludge is compacted to a silky matt surface. If necessary, a little water can be sprayed on with a spray bottle in order to obtain more sludge in case of uneven drying.

Finish:

After a drying time of approx. 24 hours (depending on humidity and temperature) the surface can be coated with Venetian soap, Punic wax or beeswax balm to polish the surface to a shine.

Dry Paints and Color Pastes

Up to 10 % pigments (by weight) can be stirred into the putty. The lime cannot bind more and chalking would occur. If the dry paints, also called pigments, are stirred into the putty, a beautiful coloured mass is created. However, there is a high probability that pigment spots will appear. This means that some pigments leave traces in the form of strokes and dots when the compound is applied. This does not necessarily have to be a disadvantage; it can also be seen as a nice side effect. If you want to avoid these pigment spots, mix yourself with a color paste.
This is how it works:

For 1000 g of pigments, approx. 800 ml liquid is used (160 ml wetting agent and 640 ml water). Pour the liquids into a container and add the pigments, stir well and grate; crush lumps at the edge of the container. Use a spoon, spatula or other. It is best to make a note of your recipe so that you can restore the same shade. Let this dough soak for at least 3 hours. However, the color paste can also remain overnight without any problems. During this time the container should be covered. Afterwards mix the coloured dough into the putty and stir well. The best mixing result is achieved if the contents are emptied into a separate bucket and mixed again well with a mixer. The putty is then immediately ready for use. Pigments have the highest colour intensity and set no limits to your creativity. But you should only use lime compatible pigments like ours.

The fillers, whether dyed or in natural white, can be stored for many years if stored correctly. For this purpose, the putty must be covered with a foil and a layer of water. The container must be closed tightly.

Exception: Ultramarine blue, the color paste and also the prepared putty, must always be applied on the same day and cannot be stored.

Tip: If chrome oxide green, cobalt blue, titanium white or similar hard pigments are processed, a Venetian PVC smoothing trowel is used for compacting. If you compact with a steel spatula, the pigments grind off the steel and metal abrasion marks are the result as grey stripes and stains.
