Unpainted surfaces:
New plaster and concrete substrates can be painted after 4 weeks of seasoning. Clean these surfaces from dust and dirt, smooth out irregularities and losses with putty. Gypsum boards, cardboards and putty may be painted after they are fully dry. In case when unevenness of the surface is considerable, the wall should be even with leveling mortar and afterwards apply on the whole surface smooth putty. In case of small unevenness you may apply smooth putty at once. The use of above mentioned mortars and putty should be done according to data sheets of these products. Machine plaster with visible glossy sinter surface should be sanded and clean from dust. Then apply one coat of Tikkurila OPTIVA PRIMER, as finishing coat apply two coats of Tikkurila OPTIVA SEMI MATT [20] paint.

Previously painted surfaces:
Wash the surface before coating and remove grease and dirt and loose and flaking fragments of old coat. Sand glossy surfaces and smooth out irregularities and losses with putty. Paint with gloss grade: satin, semi-matt, semi-gloss and gloss should be sanded on the whole surface before final dusting. For sanding use sanding paper with grain 150 - 200. Prime the whole of substrate with Tikkurila OPTIVA PRIMER. Paint twice with the Tikkurila OPTIVA SEMI MATT [20] paint.

Surfaces painted with glue or lime paint: Remove thoroughly the lime or glue paint. Clean the surfaces from dust and dirt, smooth out irregularities and losses with putty. Then apply one coat of Tikkurila OPTIVA PRIMER, as finishing coat apply twice the Tikkurila OPTIVA SEMI MATT [20] paint. In case of loose substrate prime with impregnate Tikkurila SUPRABILIT.
Before application thin sufficient amount of paint from one production batch to avoid possible colour difference. Before painting stir the paint thoroughly. Depending on substrate porosity apply 2 coats of Tikkurila OPTIVA SEMI MATT [20] with brush, roller or spray. For colours of particularly weak hiding power (marked within the tinting system) it may be necessary to apply additional coats. In case of applying colours marked in tinting system as weakly hiding (LH) and intensive colours from C base, it is recommended to use priming paint Tikkurila OPTIVA PRIMER tinted to a colour close to the colour of finishing paint. The painting tape should be  removed immediately after painting, before the paint will dry.  It is recommended to use ANZA painting tools. Notice: Full resistance properties to wet cleaning, according to PN-EN 13300, coating achievs after 28 days from the end of painting.
