When the stripping of doors makes sense

As an effective and effective alternative to the grinding of old paints is the pickling of doors. The alkaline alkalis dissolve old paint, so that they can be removed well after the contact time of the stain. Since paint strippers are chemically aggressive, comprehensive occupational safety is absolutely necessary.

Advantages of pickling compared to grinding

There are several reasons for leaching instead of grinding. While a new covering coat of paint can make old colors disappear, old paint has to be completely removed to work up and expose the grain and structure of old doors. For a later glazing of the doors, the stripping with priming is usually unavoidable.

In spite of the harmful chemical constituents of stain, an often important advantage over the sanding of the doors is the working volume during paint stripping. While sanding is loud and produces a lot of flying dirt, pickling works almost silently. The loudest possible noise is created by the blower of a Heißluftföhns.

1. Occupational safety

As all etchants etch and develop toxic fumes, you must ensure a well-ventilated workspace before use. If possible, you should pick off suspended door leaves outdoors. In the interior and door frames, a good ventilation must be guaranteed and endangered living beings such as children, pets and sensitive plants are kept away.

2. Create protection

Before you open or mix the selected mordant, put on alkaline and acid-proof protective gloves. Wear respiratory and eye protection and wear long-sleeved clothing.

3. Touch / open stain

Depending on the pickling agent, you must first open the prepackage and, if you need to mix the agent, use alkali-proof glass or ceramic containers.

4. Apply stain

Apply the stain with a brush in long strokes on the door surfaces. Make sure that as little stain as possible is removed and catch the drops with a container or lye-proof cloth. Leave the stain in accordance with the manufacturer's instructions.

5. Remove paint

Use a spatula to peel off the old dissolved paint or peel off with a puller. Careful warming with a hot air blower makes it easier to detach.

Tips & Tricks

Old paint residues and paint strippers must be treated as hazardous waste and disposed of accordingly.
