KPRO SILICONE RENDER WHITE 1.5MM 25KG
KPRO S-SR 1.5mm Silicate-Silicone Render is a premixed thin coat wet resin render which
provides a smooth even textured finish on a variety of substrates. The hybrid product is
through coloured and will provide a long lasting, durable, permeable, low absorption, dirt
resistant, low maintenance finish. The product is formulated to protect against biological
contamination e.g. fungi, mould and algae.
KPRO S-SR 1.5mm thin layer render can be used on a variety of substrates including
external wall insulation systems, concrete, render carrier board, cement based renders
and gypsum plasters.
Product Use
KPRO S-SR 1.5mm is ready to use and can be applied by hand or machine to provide an
even textured uniform coloured finish. In the event of spray application caution should be
taken to avoid shadowing that can occur with obstructions such as scaffold rails and
platforms. The render should not be applied any thicker than the grain size of 1.5mm.
Substrate Preparation:
KPRO S-SR 1.5 can be applied to smooth, dry and clean substrates free from grease,
bitumen, dust and other substances decreasing adhesion:
– cement plasters and lime-cement plasters (age above 28 days, moisture ≤ 4 %),
– concrete (age above 3 months, moisture ≤ 4 %) primed with the priming paint KPRO
Quartz Primer QP10
– reinforced basecoats primed with the priming paint KPRO Quartz Primer QP10.
Application:
The whole contents of the container should be carefully stirred. KPRO S-SR 1.5 should be
evenly applied on the substrate at the thickness of the grain by means of a steel long float
held at the angle. Then, it should be given a homogeneous structure by means of using a
plastic float in uniform rounded movements. The finished render should not be applied
thicker than the aggregate size of 1.5 mm. The product can also be spray applied, taking
care of obstructions such as scaffold bars etc. Do not sprinkle plaster with water! Work
should be done on one surface without breaks, keeping the same product consistency.
Please Note:
Application should be performed in the ambient and substrate temperature ranging from
+5 °C to +25 °C and the humidity below 80%. The render should always be applied ‘wet
on wet’ at adjacent panels to avoid unsightly joint lines. The render should be protected
against the rain until completely dry. It is recommended to use scaffolding protection.
Winter working additives are available for colder conditions.
