Aqua OVL-49/tm Grey Stain Oil

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

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

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

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

Remove any loose and torn knots as well as resin that bleeds from the wood and clean with a suitable product (e.g. V 101 Thinner, a nitrocellulose or universal thinner).

In order to avoid the use of wood preservatives as far as possible, the construction should be designed to be water-repellent (avoid horizontal surfaces, open end-grain wood, capillary joints, water and moisture accumulation points, contact with splash water, sharp edges). Pre-treatment with Wood Impregnation [eco] improves the hydrophobic effect.

Exterior wood that needs to be protected against soft rot and blue stain must be pre-treated with a suitable wood preservative* - not necessary for interior wood (*Use biocides safely. Always read the label and product information before use).

Thoroughly sand any old coatings that are still intact.

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

Stir well.

Application by brush, spraying

Apply in the direction of the grain.

Flow cup gun: nozzle size: 2.0 - 2.5 mm; atomiser air pressure: 2.0 - 3.0 bar.

Air-mix spraying: nozzle size: 0.28-0.33 mm; material pressure: 70-90 bar, atomiser air pressure 1-2 bar.

Airless spraying: nozzle size: 0.28-0.33 mm; material pressure: 70-90 bar.

Apply 2 coats with light intermediate sanding in between.

Apply a further coat if required.

Protect end-grain surfaces against water ingress by applying multiple coats of the material in the corresponding colour. Alternatively, coat the end-grain surfaces with Induline SW-910 before applying the final coat.

Use material with the same batch number on contiguous surfaces (mix material of different batches beforehand), otherwise slight differences in colour, gloss and texture may occur.

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

Check colour, adhesion and compatibility with the substrate by setting up a trial area.

Before coating technically modified woods and wood-based materials, apply the product to a trial surface and conduct a suitability test on the desired area of use.

Pre-testing is recommended also on other woods.

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

In principle, the product is also suitable for use on wood rich in substances (e.g. oak, robinia, acacia).
However, reactions with the water-soluble substances in the wood may occur that result in discolouration of the coating film and thus an impaired optical appearance (this is particularly true of white and grey shades).

Rainfall may cause water soluble substances to bleed from wood that is rich in such substances, e.g. oak, red cedar, afzelia, redwood, etc. This may lead to the discolouration of light-coloured masonry or render.

*Information about self-ignition

In external tests, the tested product exhibited significantly lower reactivity than conventional reference products that dry by oxidation. The risk of self-ignition is therefore classified as lower.

It should be noted that the tests carried out by EPH could not take into account all possible scenarios that might occur in practice. For example, contact of objects and media contaminated with this product, such as rags or dust, with other highly flammable agents, such as dust containing cellulose nitrate or certain solvents, could lead to conditions that result in ignition.

Avoid excessive overspray.

Leave fresh spraying dust to dry before sweeping up.

Collect spray mist in fireproof waste containers and spray regularly with water to prevent self-ignition of the spray mist, especially if large quantities accumulate.

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

Low temperatures, poor ventilation and high humidity delay drying.

Drying may take longer depending on the type of wood, e.g. oak, due to substances it contains.

Ready to use

Paintbrush with synthetic bristles, flat brush, flow cup gun, airless/airmix spraying equipment

Clean tools with water or Aqua RK-898 Cleaning Concentrate immediately after use.

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.

Approx. 80 - 100 ml/m² per coat

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).

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.

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.

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.
