Aqua OML-48/tm Medium Build Oil Stain

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.

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).

Wood building elements should be constructed so they shed and do not retain water (avoid level surfaces, open end-grain wood, capillary joints, water and moisture accumulation points, contact with splash water, sharp edges), thereby reducing the need to use wood preservatives as far as possible.

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).

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

Thoroughly sand any old coatings that are still intact.

Stir well.

Application by brush, spraying

Apply in the direction of the grain.

Flow cup gun: nozzle: 1.6 mm; spraying pressure: 2.5–2.8 bar

Airmix spraying: nozzle size: 0.23 - 0.28 mm, material pressure: 80 - 100 bar, atomiser air pressure: 1.2 - 2 bar.

Airless spraying: nozzle size: 0.38 mm; spraying pressure: 80-100 bar (use yellow pistol filter)

Apply a second coat once the first has dried.

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 coating to a trial surface and conduct a suitability test on the desired area of use.

Do not use below +5 °C

If the temperature is too low or the humidity too high, it will take longer for the material to reach the desired properties.

Each layer of stain results in a more intense colour and a glossier finish.

Substances in oak may bleed, causing dark discolouration, when coated with water dilutable dispersion stains.

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

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.

Only use the clear and white versions for exterior surfaces that are not exposed to direct weathering, such as soffits, etc.

Due to the different covering properties of white and pastel varnish colours, the optical appearance may vary depending on the substrate. It must be checked in advance whether discolouration of the varnish may occur due to substances contained in the wood.

Due to the low UV protection of these colour shades, shorter maintenance intervals must be expected.

In order to take account of and clarify these issues, a trial surface must be prepared in order to ensure that the surface meets expectations.

Dust-dry: after approx. 1 hour
Overcoating: after approx. 8 hours

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 acrylic 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.

As contaminated fabrics can have a tendency to spontaneously combust, soak them in water before gathering them together under water in fireproof bins and disposing of them.

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. 60 ml/m² per coat
Min. 2 coats

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 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).

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.
