Base preparation

   The basis must be dry, solid, cleaned from dust, mud, oil, remains of chalk and lime mixtures or paint. Prior to plastering, the basis must be treated with IVSIL OSNOVA primer, or IVSIL BASIS-BETON primer, if the basis is made of concrete or others solid, non-absorbing surfaces (big size silicate bricks with smooth surface, of ceramic bricks). Strongly absorbing bases (gaze and foam concrete, gipsum plaster, anhydrite) should be primed with IVSIL GLUBOKOGO PRONIKNOVENIYA (primer penetrator).

   If the curvature of the walls and there are deviations from the verticaevelling, levelling of walls is made with the help of installed markers.

   Required temperature of air and basis is from +5C to +30C.

Mixing of mortar

   Dry plaster mix is poured into a mixing bucket with clean water in proportion of 1 kg of dry mix per 0,45-0,5 l of water, then thoroughly stirred manually or with the help of mixing drill, until homogeneous, elastic mixture without any lumps or clots is received. The mixture is left for 5 minutes and then stirred again. Prepared plaster mixture should be used within 1 hour.



   Ready plaster mixture is applied with the help of plaster trowel to the surface in a layer of 5 to 20 mm and initially levelled and squared with a stick. If the surface is being prepared for painting, after plaster mixture starts to set (in 1 hour after final levelling) the surface should be wet with water and smoothed by a plasterers trowel or a plasterers float. If necessary, levelling can be done in several layers. In this case the first layer of plaster should be roughed (“combed” with a plastering comb in the form of a swallow tail) and then let to dry for 1 day.

Consultation on the pplication materials



   White gypsum plaster IVSIL SPARK (New product! Available since February, 15, 2010). Gypsum based plaster with light filler and special modifying additives. Gypsum plaster for levelling of walls and ceilings, which are made of concrete, aerated concrete, bricks, foam concrete, gypsum-fibre boards or stone. Gypsum plaster is suitable for interior jobs in premises with normal level of humidity, this plaster is applied manually.

   Finishing-off white gypsum plaster, easy to apply, spread, smooth and polish to produce perfectly even, smooth surface (finished off). After being polished the surface is ready for further application of paint or wall paper, without any other finishing-off product. This plaster is elastic enough to be easy for application and floating, it has high level of strength and adhesion to the basis.

   This gypsum plaster levels walls and ceilings and can be applied in a layer of 5 to 30 mm in one go. Low level of consumption (one and a half time lower than a standard level for plasters, it is about 9-10 kg per 1 square metre with thickness of 1 cm) is cost effective, and light weight of this plaster prevents from overloading of walls and foundation of the building. Due to its natural basis this plaster is ecologically clean and is recommended for use in accommodation houses, apartments, hotels and office premises. Whilst drying it does not crack and provides smooth, even surface. White colour of gypsum plaster IVSIL Spark stays clean and bright when further painting-vanishing materials or wall paper is applied. Fairly soon we will be ready to offer our clients a new variation of gypsum white plaster for machine application.

   The basic price of white gypsum plaster IVSIL SPARK is 257 roubles/30 kg. The prices of other plasters can be found in the section «Price List».
