Remmers Aqua VL-66/sm-Venti Coat 3in1 is a water-based one-pot coating system with a sealing effect for high-value wooden structures, with a wide range of uses that include:

• For use on interior and exterior wood
• Dimensionally stable wood building elements: e.g. windows and doors
• Wood building elements with limited dimensional stability, e.g. folding shutters, matchboarding, summerhouses
• Wood building elements with no dimensional stability: e. g. fences, framework, carports, planking
• Not suitable for coating floors (terraces, wooden decking, etc.)
• For use by professionals
• 2000+ colours available, in RAL, NCS and British Standard

Preparation

Substrate requirements

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

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

Substrate preparation

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

Thoroughly sand any old coatings that are still intact.

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

Aqua IG-15 Impregnation Primer IT* should be used to pre-treat wood in outdoor areas which requires protection against insects, rot and blue stain (omit step for wood in indoor areas).

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

Directions

Conditions for use

Temperature of the material, air and substrate: from min. +5 °C to max. +25 °C

Stir well.

Apply with a brush, roller or by spraying.

• Flow cup gun: nozzle size: 2.0 - 2.5 mm; atomiser air pressure: 2.0 - 3.0 bar.
• Airless spraying: nozzle size: 0.23 - 0.28 mm, material pressure: 80 - 120 bar.
• Airmix spraying: nozzle size: 0.23 - 0.28 mm, material pressure: 80 - 100 bar, atomiser air pressure: 1.2 - 2 bar.

Re-coat once dry.

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

Tips on Use

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

Check the product’s compatibility with the substrate and its insulating effect by applying a trial coat.

The colour shown on the sample does not appear until the material has dried.

Drying

Dust dry: after 1–2 hours

Can be overcoated: after 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 insulating effect.

Thinning

Ready to use

Notes

Insulation of resins and substances contained in the wood.

The instructions regarding coats, application volumes and drying times for the coating system must be followed to ensure the best possible insulation for water-soluble substances contained in the wood (flat surfaces and branches). The first coat can activate substances in the wood and discolour the film on the coating, which will lock the substances inside the film. The second coat of insulating product will then seal off the substances contained in the wood.

At least two coats of the product are required to achieve an efficient insulating effect.

If discolouration continues even after following these steps, we recommend contacting our RTS (Remmers Technical Service).

Bleeding resin is a natural phenomenon and cannot be prevented by coating measures, see BFS Code of Practice No. 18.

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.

On planed larch and softwoods with a high resin content, the coating may have reduced adhesion and resistance to weathering. This is especially the case on horizontal year rings, knots and areas of winter growth that are high in resin. Maintenance and renovation must be carried out more frequently on these surfaces. The only remedy for this is pre- weathering or very coarse sanding (P80). If these wood types are rough-sawn, considerably longer maintenance and renovation intervals are to be expected.

Tools / Cleaning

Acrylic brush/synthetic fibre brush, microfibre paint roller, flow cup or airless spraying equipment

Clean tools immediately after use with water and detergent.

Ensure that any residue from cleaning is disposed of correctly.

Storage / Shelf Life

If stored unopened in its original container in a cool, dry place and protected against frost, the product will keep for at least 12 months.

Personal Protective Equipment

Respiratory protection with a particle filter P2 must be worn during spraying, together with protective goggles. Wear suitable protective gloves and clothing.
