FAST Kornik SI a thin-layer siloxane plastering mix 15kg
thin layer siloxane plastering compound with a structure
FAST KORNIK SI is a high quality water-based decorative siloxane plaster, designed for making durable PVC trowel with a 2 and 3 mm thick woodworm texture inside and outside the building. FAST KORNIK SI is a plaster ready to be applied on all durable and smooth surfaces occurring in the building industry, such as cement plaster, cement mortar, concrete, sandstone, etc. and covered with strong adherent paint coatings. It is a component of the FAST S system.
FAST KORNIK SI is based on a water based siloxane emulsion and an acrylic-styrene dispersion - it forms a coat strongly bound to the substrate. It is vapour-permeable and surface-hydrophobised. Thanks to this, the surface is characterized by an anti-perspirating effect. The coating has a significantly reduced wettability, i.e. the penetration of water with substances dissolved in it, thus inhibiting the penetration of dirt carried mainly with water and the development of microorganisms such as algae and fungi. The final effect is a reduced tendency to get dirty, giving the effect of self-cleaning of the coating and excellent resistance to weather conditions. Supplied in a wide range of colours according to FAST COLOR SYSTEM . It contains agents eliminating the development of algae and fungi on the plaster surface.

Preparation of the surface
The surface should be even, strong and dry, free from all kinds of impurities that reduce the adhesion of the mortar, i.e. dust, lime, grease, remains of old paint coats. In order to reduce the absorbency, the surface should be primed with one of FAST's primers. FAST GRUNT M should always be primed before each application to increase plaster adhesion, regardless of the type of surface. It is recommended to use a primer in the shade of the selected colour FAST KORNIK A.
The plaster mass can be applied to following suurfaces:
- cement and cement-lime plasters (after a minimum of 28 days from application and humidity not higher than 4%) primed FAST GRUNT M
- concrete (more than 3 months since application and humidity not more than 4%) primed FAST GRUNT M
- gypsum substrates (humidity < 1%) primed FAST GRUNT G and FAST GRUNT M
- layer in the insulation system reinforced with mesh, made on FAST SPECJAL mortar and primed FAST GRUNT M above 3 days
Preparation and use
Before applying the mortar, mix the contents of each package with a slow-running drill in order to level the consistency. In the case of too dry mass it is permissible to add 100 to 150 g of water. Apply a thin layer of plaster mass to the previously prepared and primed surface, using a stainless steel float to the thickness of the grain. After a short time, depending on the conditions at the time of application, we can invoice it with a plastic float. Trowel the plaster with circular motions. When applying the plaster, the general rule of thumb should be observed when applying the plaster "wet on wet". It is also possible to apply this plaster by spraying, which significantly reduces the cost and time of application. Details of the exact technology are available at www.fast.zgora.pl or from technical representatives.
Tools and containers should be clean. When applying and drying the plaster, observe appropriate atmospheric conditions, i.e. substrate and ambient temperature from +5°C to +25°C, lack of strong sunlight, rain and too high relative humidity above 75%. The plaster drying time at an optimal temperature of +20°C is 12 to 48 hours.

o Confirm that the colour corresponds to the order before application. Complaints concerning colour will not be considered after the product has been applied.
o In order to avoid shade differences on one architectural surface, work should be carried out without interruptions, using plaster packaging, previously mixed with each other in a large bowl.
o Protect the plaster against adverse weather conditions with scaffolding covers until it dries out completely.
The recommended scope of application of the product or the application method specified in the data sheet does not exempt the contractor from carrying out work in accordance with the art of construction and health and safety at work. P.W. FAST guarantees and is responsible for the quality of the product, but has no influence on the way it is used and the conditions under which it was used. All technical data were measured under normal conditions, i.e. +20°C and air humidity of 60%. In the case of conditions other than the above, the drying time may change, i.e. it may be longer or shorter.
