 HUGA - Quality and environmental offensive with innovative water-based paints
Water-based paint – many advantages compared to conventional techniques
High quality product – Minimal emissions – Good working conditions
HUGA worked with international manufacturers to develop the new water-based paints. They not only meet the expectations of HUGA products with respect to top-notch surface quality, colour-fastness, toughness and gloss, but they also help to protect the environment and the climate. They are virtually solvent-free - as the paint dries, it gives off only water vapour.
Our manufacturing employees already benefit from these innovative water-based paints, because there are no more offensive smells. In the home and the workplace, doors painted with water-based paint represent a long-term improvement to quality of life.
HUGA – building on technical advantage
Consistently taking the initiative - trailblazer role in design and production
Although water-based paint has been well-established at HUGA for a long time now, few producers utilise this technology. However, to HUGA the new paint technique represents yet another step in the expansion of its company portfolio. Not only clear lacquers, but also glazes and various coloured paints are used to produce trend-setting finishes. Other highlights are in progress. New looks and matching finishes of different components are important to HUGA.
 Wood veneer - every door an original
Every tree is different. Its growth, its grain, the wood - no two trees are alike. That's how you know you'll be setting your own new trend with wood veneered HUGA doors in your home and business.
Our experts select only the best trees. They painstakingly check the strength, colour and evenness of the material.
Best material - perfect workmanship
A genuine HUGA door consists of the highest quality raw materials crafted in a series of exacting steps. We demand the best in both looks and function!
Quality sliced veneers are hand-picked by an expert. For every single door. If desired, book-matched too, of course.
Lustrous varnished surface
When it comes to lacquer we subscribe to quality, durability and a flawless appearance. We apply the final coat in a casting process to all appropriate types of wood.
You can see the difference - in our top-quality, lustrous lacquered surfaces.
For the sake of the environment
We use only environmentally-friendly acrylic and water-based systems from certified producers.
 The veneers that are applied to all components of the doors and frames are bonded onto the subsurface with various different adhesives. Using a water-based stain or water-soluble colours (also diluted combination stains and water alcohol combination colour systems) can therefore cause problems with the surface coating in some cases. Depending on the type of timber, the same applies to the most commonly used veneers, which can produce different shades of stain, as the front and the back sides of the veneer absorb the stain differently. Sample stain all components.
Please note that unfinished products supplied by us are only pre-sanded. Pay special attention to glue spots. These cannot be avoided in the pores of some types of timber. The PVAC glue, hot-melt type adhesive or urea resin adhesive used does not react to normal commercial water-based stains. We therefore recommend using either dyes and stains made of organic solvents, or levelling agents.
 All unfinished products which leave our factory have been pre-sanded and may need to be sanded again.
- We recommend initially sanding with a grit of, for example, beech 220, oak 180 (further examples upon request).
- If further sanding is required, use a finer grit of 40.
- When sanding always make sure that the sandpaper is sharp. Smooth sanding belts do not sand, they
clog up the timber surface. The ability of the surface to absorb the stain is reduced and the colour turns out lighter.
- Sand all components using the same grit and, if possible, with sandpaper from the same manufacturer.
- The more coarsely the timber surface is sanded, the more stain is absorbed, i.e. the darker the stain
will be.
- Orbital sanders are not suitable for sanding timber. If timber is sanded too coarsely across the grain, an erratic,
patchy stain will be the result.
- Dust off carefully, but take care that the compressed air does not introduce oils, diluted matter, wax or silicone to the surfaces. Foreign bodies lead to spotting on the stain. Sanding dust in the pores accentuates the pores, sanding dust on the surface results in a blotchy-looking stain!
- Fibre, brass and bronze brushes are suitable for degreasing, removing resin and glue and for application purposes. Do not use steel brushes!
- Carefully sand off glue stains. Before processing, the glue should be coloured by hand in the same shade as the later timber stain. This is of course not possible with the products we supply. Therefore please refer to our recommendations at the end of these instructions.
- Check the door surfaces in particular for remnants of taping paper and its adhesive. Remove any remnants with warm water and appropriate sanding before staining.
- Please note certain types of timber can make the stain patchy, such as pine, spruce and larch, and in some cases Canadian maple and oak. If necessary prepare the surface according to your staining system. Your paint supplier will advise you.
- Carry out a stain test on all components!
- Paints, stains, hardeners and thinners containing more than 2.5% xylene or naphtha can cause the edges to become detached. Refer to material safety data sheets.
- Take note of the storage and processing temperatures of the stains used and store the products to be stained at the same temperature.
- Remove all metal fittings before staining!
- When bleaching, ensure compatibility with the surface finish coatings and stains to be used later.
- Protect freshly-stained components from sunlight and draughts.
 The fine sanding needed for the final surface treatment must be carried out on site.

 Doors and frames do not require any special treatment. If required, squirt a little washing-up liquid or mild cleaner into warm water. When selecting a cleaner, ensure that it does not contain any abrasive, strong or alcoholic (water-soluble) solvents. Use a damp, lint-free cloth to wipe over the surface finish.
Regardless of surface finish, please note the following:
- never leave the surface finish damp or wet for any length of time because timber
materials can absorb water and become warped.
- Wipe any damp or wet spots dry without delay, using an absorbent cloth.
- Do not use furniture polish. Some care products and polishes can leave the surface finish
unsightly and greasy.
- Do not press too hard when wiping clean, to avoid shiny spots.
