Finngard Primer S Masonry Primer
Data Sheet - Finngard S Primer
Description
Solvent-borne acrylic primer for use on exterior facades. Binds and stabilizes powdery surfaces and reduces efflorescence prior to the application of Finngard Opaque.
Examples of use
New or previously painted exterior facades including concrete and rendering. Finngard Primer S is not recommended for use with silicate paints or for use on substrates previously painted with lime paint.
Technical data
- Solids volume: approx. 10%
- Density: approx. 0.8 kg/l
Specifications
Preparation
Surfaces must be clean, dry, and free from grease, dirt, salts, all loose material and surface contamination. Use suitable Tikkurila products for mould removal and cleaning. Ensure that surfaces to be painted are bonded to the substrates. Re-render or repair all areas of failure, cracks, holes, etc., with suitable repair mortars. Glassy or glossy concrete surfaces should be mechanically abraded. Note: The relative humidity of concrete and cement-rich substrates should be less than 90% prior to priming and painting.
Application
Stir thoroughly and apply, by brush, roller or low-pressure spray, 2-3 coats of the primer using wet-on-wet method of application with e.g. approx. 10 minutes between coats. The number of coats to be applied will depend upon porosity, absorption and condition of the substrate. Finngard Primer S normally requires no thinning, however on hard and less absorbent surfaces it may be thinned by up to 50% with White Spirit.
Painting conditions
All surfaces to be primed must be dry, the temperature of the air +5 deg. C, and the relative humidity of the air below 80%.
Coverage
2.5-5 m2/l per coat. On very porous and rough surfaces the spreading rate could be reduced to 0.5 - 2m2/l.
Drying times
At 23 deg. C and 50% relative humidity of the air Finngard Primer S is normally touch-dry in 4 hours and recoatable after 24 hours (or next day).
Cleaning of tools
Clean with White Spirit immediately after use.
Prevent environmental damage
Empty cans should be recycled or disposed of in accordance with local regulations. Liquid waste should be destroyed according to the local regulations.
