Lacquer - Acrylic lacquer - Alkyd resin lacquer - Synthetic lacquer: alkyd

The large variety of paints makes this assortment area in need of explanation.

Therefore, let us advise you!

Although brand name coaters such as Alpina are investing a great deal in a largely self-explanatory packaging design, it must first be clarified which of the two different types of paint is generally suitable.

On the one hand, there are water-based or water-dilutable acrylic lacquers, on the other hand solvent-based alkyd resin lacquers, which are also referred to as the "classic" synthetic resin lacquers. Both paint types are offered by the hardware store, because they differ in their properties - not only in terms of processing, but also in terms of processing Surface Quality.

Water-thinnable acrylic lacquers are well suited for all do-it-yourselfers who want to paint in an environmentally friendly way. Because she contain less solvents and are therefore very mild odor.

In addition, tools and brushes can be restored easy to clean with water, The white coatings even have a special advantage: they do not turn yellow.

The Federal Environment Agency also draws waterborne coatings with the "Blue environment angel" out.

Synthetic resin lacquers - alkyd resin lacquers

Alkyd resin paints are easy to process and have a very high hiding power, Their good course also ensures evenly smooth surfaces.

Synthetic resin paints have one high impact, impact and abrasion resistance, All this makes them durable and perfect for anything that is subjected to special stress.

Danger symbol "Dangerous for the environment"

Labeling: environmentally hazardous substances (tree & fish)

However, synthetic resins of the older generation have the disadvantage that they bring odor and environmental pollution through their aromatics-containing solvents.

Therefore, since the 01.07.2002 a labeling requirement in accordance with EU Directive, according to which conventional synthetic resin with the orange danger symbol "Dangerous for the environment" must be provided. Since then, many environmentally friendly paints have been launched on the market.

Aromatic-free synthetic resin coatings dispense with the most aggressive component of conventional solvents, the aromatic hydrocarbons.

The aromatic-free paints have the following advantages:

Significantly lower odor, improved health protection for the processor, lower allergy potential, improved environmental protection, lower ozone pollution, painted rooms can be reused more quickly.

Water-based acrylic paint

In contrast to conventional alkyd resin or synthetic resin paint, which hardens by a chemical reaction, water-based paint dries purely physically, d. H. by the evaporation of the water or solvent mixture. The binder is present as finely divided droplets or polymer particles in water, the so-called dispersion.

These polymer particles approach by the evaporation of water and fuse to the actual paint film. The drying is irreversible, i. after complete drying, the paint film is water insoluble. Acrylic lacquers are labeled with the environmental seal Blue Angel according to RAL-UZ 12 a.

What are the advantages and disadvantages of an acrylic varnish?

  • environmentally sound
  • odor
  • fast drying
  • resistant to yellowing
  • short open time
  • no glossy effect
  • not so hard-wearing

Clearcoats, glazes and paint colors

Paint is a collective term for a variety of coating materials based on organic binders. Depending on the nature of the organic binders, lacquers contain organic solvents and / or water and optionally additionally pigments, fillers and other additives.

The group of paints can be divided into the following three groups:

  • clearcoats are unpigmented paints, which may have a color of their own depending on the binder
  • glazes are paints with a low pigment content, which let the surface shine through. They are usually used on wood
  • paint colors are opaque, pigmented paints. Paints are primarily surface protection materials and have to fulfill the most varied tasks in this function.

Today there are almost for every purpose and scope specially coordinated paint materials, Without paints there would be no cans, because all cans are coated to protect against corrosion on the inside. Likewise, the phone calls or the production of electric motors without Electrical insulating varnishes not possible.

The so-called "Coatings" represent only a small segment of the lacquer market. Building lacquers are used for the protection and decorative design of building components and furniture.

They are available in different degrees of gloss and limitless color variety. While the topcoats, the final coatings, can be applied to almost any primer, it is important to make sure that the basecoat is suitable for the particular substrate. Likewise, it must be clear before painting what the coating film will be exposed to.

In particular, in the color tone selection must be taken into account that not every shade is UV resistant and thus a change in color due to strong sunlight is unavoidable. There are several for most applications alternative paint systemsthat put consumers in the agony of choice. Should he now use an alkyd resin paint, a water-based paint system based on acrylic or a high-solid paint?

The alkyd resin paints have proven themselves for decades. They are highly durable, easy to work with and become a pro about 90% used for painting. Because of the significant odor in the alkyd resin and high-solid paints, many consumers opt for the use of a water-dilutable paint. The use of acrylic paints, however, means that compromises must be made in the surface quality and in the processing properties.

Paint professionally

Prepare underground

When painting, the better the substrate has been pretreated, the easier it is to paint and the more beautiful and durable the result. That's why the First remove dirt and grease from the surface become.

The surface should be finely honed become (180-grit abrasive paper for pre-grinding and 280er sanding paper for sanding), then remove the dust. Cracks or bumps are also to be sharpened and smoothed with putty. This must be dried, reground and dedusted.

Apply paint

For a clean finish when painting, roller and brush always need evenly wetted with paint his. Swipe never dripping wet.

Always start painting with a brush Corners and edges, but beware:

Attention:

Do not spread too far in the area, so avoid approaches.

Then the paint in horizontal tracks Apply. Large surfaces are painted by quickly applying the paint in webs, spreading it across and possibly pulling it through in the opposite longitudinal direction.

In conclusion With the brush or roller again, paint vertically over the surface to create a uniform surface.

Since paints (especially water-based paint) dry very quickly, divide larger areas into smaller sections and wet-on-wet, leaving no time between painting the corners and edges and painting large areas to avoid visible marks.

Basically:

The same type of lacquer should always be used for all steps of painting a surface. Mixing waterborne acrylic and synthetic resin is not recommended.

Order with the right brush

For a nice result, it depends on the choice of the right tool. When painting with the brush this half maximum dip in the paint can and good at the edge.

Tip:

To keep the edge of the can clean, you can stretch an adhesive tape across the can and then brush it off.

Synthetic resin paints are best applied with natural bristle brushes, finest finishes are included China bristles possible. For water-based paints, special acrylic brushes are recommended because they absorb the paint better and allow a smooth flow.

flat brush are ideal for large areas, Rundpinsel rather for fine work like edges and narrow places suitable. High quality paints can also be used in the spraying to process. For this, the respective technical information of the device manufacturer must be observed.

Tip:

In order to wash out as little paint as possible, the brush should be spread well on newspaper. If you want to continue working the next day, the brushes can be stored hanging in the water (for acrylic paints) or in brush cleaners (for synthetic resin paints).

Order with the roller and the roller

Pour the paint into a smaller paint tray. Then immerse the Moltopren scooter in it and Carefully wipe off on the corrugated surface, Especially suitable for large areas, there are various rollers for water-dilutable paints and synthetic resin coatings.

Attention:

When working with paint rollers made of foam or Moltopren small bubbles may arise on the surface. In this case, roll over the surface again very lightly without dipping the roller into the paint again. The bubbles then open and the painting becomes smooth.

Shades: Standard and Trend

color palette

The standard color selection shows a selection of classic water-based acrylic and synthetic resin paints RAL colorsthat are needed a lot.

In the case of branded collections, for example, there are 14 different shades in each case in gloss and satin matt in the case of acrylic paints, as well as in high gloss and semi-gloss in synthetic resin paints. In addition, there are a total of 28 trend colors, which were developed especially for the harmonious interior design inside and out.

Since the end user often has no courage to color, he needs appropriate suggestions. An elegant presentation of trendy colors makes the selection a pleasure.

For this there are brochures from brand manufacturers - for example "Color & Emotion"that put into practice "Color shaping Recipes" in the living area - this applies both to the colored walls as well as to the associated paint typical surfaces.

Increasingly, old craft painting techniques are desired, such as Dabbing, stenciling, wiping and wrapping, These can also be produced with water-dilutable acrylic paints in a particularly attractive surface finish.

After painting

Dispose of all materials according to regulations. Dry and empty containers for recycling, brushes and rollers that have become hard to throw in the household waste. Liquid residues are to be disposed of as hazardous waste in the collection points.

To store paint residues, close the can tightly and turn it over for a short time. This keeps the can hermetically sealed. Coatings should be stored in a dry, cool and frost-free place.

Window coatings: Almost universally applicable

Quality window coatings - as the name suggests - are used in particular for windows and doors, used both for interior and exterior coatings.

The background of the material to be painted plays virtually no role today. If Wood, zinc, aluminum, steel, plastics or masonry, Quality window paint is almost universally applicable to any surface. But some hints are to be considered!

Window and door paint is solvent-based and water-dilutable. The trend, however, clearly goes to the latter, because they are environmentally friendly and thus the ecological requirements satisfy.

The "Blue Angels" attests to this. Water-thinnable window coatings such as those from Krautol are silky-glossy and feature a particularly high blocking resistance based on acrylic resin.

Quality window coatings are used especially for windows and doors. Both for interior and exterior coatings, such as Cladding, porches or glasshouses, these paints are used. The substrate can be wood, zinc, aluminum, primed steel, plastics as well as plaster, masonry, concrete or fiber cement.

Water-thinnable quality window coatings have an excellent Block and weather resistance, you are low odor, resistant to yellowing, are highly elastic, dry quickly and through. you are moisture-regulating, do not blister, burst, and are resistant to common household cleaners.

Paint window

The substrate should be stable, dry, free from loose particles, dust, oil, grease and other substances acting as a release agent. Raw wood is previously with Holzgrund primed.

Iron and steel will after extensive rust removal With metal base primed. Zinc should be with before Plastic fleece and diluted ammonia cleaned and then washed off with water Zinc and Alugrund primed.

Aluminum must be degreased in advance with nitro dilution and with Plastic fleece or sandpaper roughened. Then the primer takes place with Zinc and Alugrund, Plastics should also be cleaned with nitro thinner and degreased. The priming is done with a special plastic base.

Steps:

  1. Loose-fitting paints are carefully removed with coarse sandpaper or a wire brush - dust and grease are added Universal thinner washed.
  2. Well adhering old paintings can be used with 180 Grind sandpaper and then treat with Universal Thinner for later painting.
  3. Glass seals, wood and miter cracks should be repaired beforehand. Defects are to be spotted before. Old synthetic resin coatings can be revised without hesitation after appropriate pretreatment.
  4. The compatibility with sealants, however, must be checked in each case. Basically, you should know that the window or door paint has to be stirred well before processing.
  5. The undercoat is with 10% water to dilute, which will be top coat undiluted processed. The primer is roughened with sandpaper after drying before applying the top coat.

Paint wooden doors

Apply the 2 coat (paint coat).

For untreated wood and sanded areas, a primer coat is required. It penetrates deeply into the wood and fills the pores, leaving the following finishes on the surface. For this acrylic priming paint with 10% water or undercoat color with 10% turpentine substitute dilute.

After drying the area with 180 Roughen sandpaper and remove dust. Fill cracks and irregularities with paint filler or wood putty.

Then roughen again and dust off. For the undercoat, apply acrylic priming paint or primer paint undiluted.

Then the areas with 300 Roughen sandpaper and remove dust. Depending on the substrate, you may need one or two coats of acrylic lacquer, synthetic resin lacquer or high solid lacquer. Before final coating, roughen the surface with 500 grit paper and remove dust.
