Clay filling and smoothing putty

Clay filling and smoothing putty for subsequent coating on CLAYTEC clay finishing plaster (fine) and other sufficiently smooth substrates such as plaster surfaces, plasterboards, gypsum fibreboards etc., or for YOSIMA coloured clay filler. The clay filling and finishing putty allows you to smooth out imperfections and holes, and is also suitable for use as an overlay for the entire surface. Clay filling and smoothing putty is a multi-purpose tool with a wide range of possible applications. It is available in natural brown and natural bright. Natural bright is recommended for light-coloured finishes.

Product and application method
Filling and smoothing putty for subsequent coating on CLAYTEC clay finishing plaster (fine) and other sufficiently smooth substrates such as plaster surfaces, plasterboards, gypsum fibreboards etc., or for YOSIMA coloured clay filler and clay design plaster.

Ingredients
Foam glass, clay and loam, powdered limestone, talcum, cellulose, methyl cellulose < 1%.

Supply forms, coverage
10 kg bucket 33/EUR pallet (7.5 litre putty, approx. 7.5 m2 area at 1 mm thickness).

Storage
Can be stored dry and cool for an indefinite period.

Preparation
The 10 kg dry mass is gradually stirred into approx. 5 litres of clean water with a drill (≥ 800 Watt) or agitator and agitator paddle (Ø 125 mm). Working consistency should be pasty, corresponding to the desired application method with smoothing trowel or spatula.
Leave the mixture alone for 30 minutes, and then stir thoroughly again. The putty is now ready for processing.

Substrate
The substrate must be stable, non-elastic, frost-free, dry, clean, free of salt and sufficiently rough.

Working method
Imperfections and holes must be filled in first, if necessary several times.
On each occasion, leave them to dry. Sweep surfaces before applying the putty.
The putty can be applied to a thickness of 0-3 mm in each working period.
The clay putty is trowelled off on the surface. If smoothing is required, this is carried out using light pressure and a ‘closed trowel’ for as much as is necessary to achieve a smooth closed surface.

Working time
Once mixed, the putty remains usable for 24 hours if kept covered.

Hardening
The hardening time is 24 hours, depending on the drying conditions and absorbency of the substrate.

Additional treatment
After hardening is complete, the surface can be dry sanded by hand or machine.
100 grit sandpaper or 100 grit sanding discs are both suitable. If necessary, finer papers can be used. Machine sanding using a long-necked sander (‘giraffe’) is also possible.
To coat clay filling and smoothing putty, natural bright, use ready-mixed CLAYTEC clay paint (CLAYTEC 13.000).
The first coat should be somewhat diluted, the second undiluted. Coating can also be carried out with CLAYFIX clay coating, after priming with CLAYTEC WHITE primer (CLAYTEC 13.415-.410). Natural bright filling and smoothing putty is recommended as substrate for light colours. Spray application is recommended for achieving particularly smooth surfaces. Clay filling and smoothing putty also forms a very suitable substrate for YOSIMA coloured clay filler and clay design plaster. In these cases, priming is not necessary. Again, natural bright filling and smoothing putty is recommended as substrate for light colours.
