Aqua HSL-36/m Premium Wood Protection Stain 3in1

The substrate must be clean, dust-free and dry.

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

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

Completely remove old coatings (e.g. paints or medium-build stains), bark, bast and dirt.

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).

Smooth, planed wood surfaces should be sanded and dusted before the coating is applied to ensure better absorption.

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

Stir well.

Brush, spaying in closed systems only, application machine

Apply in the direction of the grain.

Apply a second coat once the first has dried.

When coating continuous surfaces, only use materials with the same batch number as 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.

If the surface is overcoated with other products it is recommended to test the adhesion to the substrate.

Clear, white and hemlock are suitable for use only on not directly weathered surfaces in outdoor areas, such as roof eaves, or as base coat.

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.

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.

Pre-testing is recommended also on other woods.

In order to eliminate the need for wood preservatives as far as possible, the construction should have a water-repelling design (avoid horizonal surfaces, open end grain, capillary joints, areas where water and moisture can accumulate, contact with splashing water, sharp edges). If this cannot be guaranteed, or if a higher level of protection is required in outdoor areas, the untreated wood can be impregnated with Aqua IG-15-Imprägniergrund IT*. (*Use biocides safely. Always read the label and product information before use.)

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

To protect against moisture, end grain and cut surfaces should be coated with Induline SW-910 after the varnishing coat.

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

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

Low temperatures, poor ventilation and high humidity delay drying.

Use a foamed protection foil between the single coated wood elements to avoid blocking.

Paintbrush with synthetic bristles, spraying in closed systems only, application machine

Clean tools immediately after use with water.

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. 150 ml - 200 ml/m² in at least 2 coats

Planed or very thick woods are less absorbent and may require a third coat

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.
