Multi-Purpose Varnish 3 in 1

The substrate must be clean, dry, free of dust, grease and loose substances, and prepared in the correct manner.

Dimensionally stable wood building elements: wood moisture content 11-15%

Wood building elements with limited or no dimensional stability: wood moisture content max. 18%

Thoroughly remove any dirt, grease and non-adhering old coatings.

Wood substrates:

Thoroughly sand any old coatings that are still intact.

Sand grey and weathered wood surfaces down to sound, bright wood.

Remove loose and torn knots as well as resin that bleeds and clean with a suitable product (e.g. Remmers thinner & brush cleaner).

Exterior wood that needs to be protected against soft rot and blue stain must be pre-treated with a suitable wood preservative* (*Use biocides safely. Always read the label and product information before use).

The drying times must be observed.

Observe BFS Code of Practice No. 18 "Coatings on Wood and Wooden Working Materials in Outdoor Areas".

Rigid PVC, aluminium (not anodised) and zinc (galvanised steel):

Use an abrasive pad to apply an ammoniacal wetting agent. Observe BFS Code of Practice No. 22 for rigid PVC, BFS Code of Practice No. 6 for aluminium and BFS Code of Practice No. 5 for zinc.

Load-bearing old coatings:

Remove any old coatings not capable of supporting a load, making sure not to leave any residue.

Only apply coatings to non-chalking substrates that are capable of bearing a load.

Refer to BFS Code of Practice No. 20.

Iron, steel:

Derust thoroughly. Remove scale layers and rolling skin (derust manually to SA 3 standard of cleanliness). The best results are achieved if the substrate has been sand blasted to SA 2.5 standard of cleanliness (DIN EN ISO 12944-4).

Round off sharp edges and ridges.

Refer to BFS Code of Practice No. 20.

Stir well.

Apply with a brush, roller or by spraying.

- Spraying parameters for light and dark colours:

Airmix spraying: nozzle 0.28 - 0.33 mm, material pressure: 100 - 140 bar,
atomiser air pressure: 1.2 - 2 bar.

Airless spraying: nozzle 0.28 - 0.33 mm, material pressure: 180 - 200 bar

- Spraying parameters for metallic colours (iron grey, DB-703):
Airless spraying: nozzle 0.33 - 0.38 mm, material pressure 180 - 200 bar,
pistol filter 300 - 600 µm.

Apply further coats once dry.

Seal opened containers well and use contents as soon as possible.

Check the product’s compatibility, adhesion and sealing effect on the substrate by applying to trial areas.

Cut end-grain surfaces at the bottom to create a water-drip edge.

End-grain wood preservative should first be applied to end-grain wood and cut surfaces in order to protect them against moisture.

Areas that are being coated or dried should be protected against rain, wind, sunlight and condensation.

Do not use on wood impregnated with boron salts.

Do not apply on lead.

Dust-dry: 1 - 2 hours
Ready for overcoating: approx. 6 hours

Practice values at +20 °C and 65% relative humidity.

The coating may take significantly longer to dry thoroughly in lower temperatures, at high humidity or if the maximum layer thickness has been exceeded.

Longer drying times can improve the sealing effect.

The product’s insulating effect may be impaired if it is diluted too thinly, if the wood is too wet or if the recommended coating sequence, application volumes and drying times are not observed. With water-based coating systems, there is always the residual risk that substances contained in the wood will leach out.

Ready to use

Brush with synthetic bristles, flat brush, foam roller, Airmix/airless spraying equipment

Clean tools immediately after use with water and detergent.

Ensure that any residue from cleaning is disposed of correctly.

If stored unopened in its original container in a cool, dry place and protected against frost, the product will keep for at least 24 months.

Bare ferrous metals: 2-3 x 100-120 ml/m²
Rigid PVC, non-ferrous metals and intact old coatings: 2 x 100-120 ml/m²
Wood: 2 x 100-120 ml/m²

DIN EN 71-3 "Migration of certain elements":

This product complies with the limits for the migration of heavy metals to children's toys according to DIN EN 71-3 and thus fulfils one of several further requirements for the safety of children's toys according to the EU "Toy Directive" (2009/48/EC).

In the presence of air and water, aluminium forms an oxide layer that can have a negative impact on the product characteristics of coatings. Therefore, when working with aluminium, the coating must be applied immediately after pre-treating the substrate.

Observe the regulations concerning design principles for wood protection.

Do not use on horizontal surfaces without drainage slopes and without edge radius, avoid accumulated moisture.

Colour deviations may occur with mica shades in comparison with printed colour charts, during touch-up work and with different application methods. Different batches of the same product should be mixed. Colour deviation according to BFS data sheet no. 25 Appendix A.3.

Larger quantities of leftover product should be disposed of in the original containers in accordance with the applicable regulations. Completely empty, clean containers should be recycled. Do not dispose of together with household waste. Do not allow to enter the sewage system. Do not empty into drains.
