Carpenter’s glue PVA D3 Farbex

The surface, which is meant to stick, must be dry – the timber humidity must be from 8% to 12%. The timber must be clean from dirt, dust, paint products, grease, oily, resin, biological, and other contaminations.
In case there are deposits of resin on the surface of the wood, they must be removed mechanically (with a spatula or a scratcher). Then clean these areas with water and detergents or universal thinner TM Maxima.
In case the wood is infected with blue stain, mould, or fungi, remove infected areas: first mechanically and then treat the wood with antiseptic for wooden surfaces TM Farbex. Correct uneven surfaces with stucco TM Farbex. Polish the corrected surface and then dust it off.
Smooth (glossy) surfaces must be grinded and then dusted off. It is necessary for better adhesion with the product.
The surfaces, which are going to be stuck, must be perfectly matched to each other. Big gaps between the surfaces cause increasing the period of hardening of the adhesive seam and reducing of its hardness.
Before using subordinate products (antiseptics, stucco, etc.), it is necessary to check compatibility on a small area of the surface, following technical directions or specialists’ advice.

We do not recommend priming before applying the adhesive.

We do not recommend diluting the adhesive. Adhesive diluting reduce hardness of the adhesive connection.
Stir the product thoroughly before use.
Carry out sticking at the temperature of air and the surfaces from +15 °С till + 25 °C, and relative air humidity from 40% till 70%. If the temperature is low, the adhesive sticks to the surfaces much longer. If the temperature is high (above + 25 °С) the moisture evaporates too quickly, and the adhesive does not manage to stick well, and the hardness of the adhesive seam can be reduced.
Apply it with a thin and homogeneous layer on both sides. Join the details and press them with pressure 1-5 kg/cm2, after you apply the adhesive. Keep pressure for 10-20 minutes. The surfaces of hard species of wood and uneven surfaces must be kept under pressure for up to 50 minutes.
Remove excess glue with a wet cloth or sponge.
Attention! The glue consumption, time, and pressure force, hardness of the adhesive seam, and adhesive effect on the wood substantially depend on the species and age of the wood. When you work with hard and exotic species of wood, you must test adhesion following all directions.
When you work with a great number of details and/or for a long period, we do not recommend keeping the container with the products open for a long time.
Do not carry out sticking under direct sunlight, strong wind, or precipitation. After you stick the details, the seam must not be affected by precipitation for 24 hours.
The adhesive seam becomes fully hard and water-resistant after 7 days.
If you use the adhesive outdoors, protect the adhesive seam with the appropriate paint products.
The tools, which you use for applying the adhesive, must be recommended for water-based products or made of plastic or stainless material.
For a quality result, you have to obtain the skills for sticking to and carrying out carpentry work.
After sticking, the wooden surfaces can be chipped and affected by dust, etc.
After sticking all existing (nails, staples, screws, and others) elements must be made of zinced or stainless steel. If you use iron elements for wooden constructions, they must be protected against corrosion with special primers or other products.
POLYSAN company recommends doing personal testing for compatibility of the products and the hardness of the adhesive seam.
Compatibility with other coatings
Depending on the exploitation, the glue can be used with different finishing coatings. The examples of compatibility are given below. Call the specialists of POLYSAN for detailed recommendations.
Previous layer – we recommend applying it on a clean surface.
Subsequent layer – water-based paint products.
The compatibility of products is recommended to be tested on a small area of the surface.
