USE

Go top
White Base Coat Mass GRUNT-FARBA is designed for proper preparation of mineral substrates prior to application of surface interior paints. Can be used for first painting (upon fresh, but appropriately aged substrates) as well as renovation one (upon existing paint coatings). It is recommended upon gypsum substrates (plasters, top finishes, finishing coats, plasterboards), but also upon cement-lime and cement plasters. Can also be used upon concrete and rough walls made of bricks, blocks, ceramic, silicate and concrete hollow blocks. The agent is manufactured white, but can also be initially tinted beneath surface paint with any general-use, water-dilutable colourants for interior paints. The agent can be applied manually or mechanically with spraying equipment.

PROPERTIES

Go top
White Base Coat Mass GRUNT-FARBA is manufactured as ready-to-use mix of dispersions of styrene-acrylic resins, fillers, pigments and modifiers. After application forms coat which unifies substrate properties – colour shade and structure – therefore facilitates application of surface paints. Its use is particularly helpful when painting plasterboards or substrates coated with point fillings or well bonded paint coatings. The use of base coat agent improves coating and bonding to the substrate, it also reduces consumption of surface paint.

SUBSTRATE PREPARATION

Go top
The substrate should be appropriately aged (gypsum plasters – min. 2 weeks, cement-lime plasters – min. 3-4 weeks), dry (humidity up to 3%), sound and cleaned of impurities which would impair bonding, particularly dirt, dust, wax and fats. Poorly bonded substrate elements should be hacked off, loose dusty fragments additionally cleaned with the use of a card.

AGENT PREPARATION

Go top
White Base Coat Mass GRUNT-FARBA is manufactured ready-to-use. After opening the container, mix the content in order to unify the consistency. In case of machine application, it is allowable to dilute the agent with clean water (max. 10%).

APPLICATION

Go top
The agent is applied with a roller, a paintbrush or sprayed with thin, uniform coats. Depending on substrate absorptiveness, the application is conducted once or twice. The second coat can be applied when the previous one dries. Time of drying is approx. 6 hours and depends on substrate type, temperature and air relative humidity. Coating with surface paint can commence 6-12 hours since the agent application, when the agent is appropriately dry. Clean the tools with clean water directly after use.

COVERAGE

Go top
The average coverage: 7 m² from 1 kg (for single painting). Actual consumption depends on substrate properties and tools used for application.
