Instructions for picking wood

While pickling refers to the chemical effect of a surface, pickling is the removal of old layers of paint or varnish using a stain.
This stain, the paint remover, is available in different versions:
What is pickling, which stripping agent is there?
Neutral strippers and chemical strippers are offered. In the latter one differentiates between alkaline strippers and solvent-based strippers. The most gentle are the neutral strippers, but not only for health and the environment, but also for the wood to be removed. Especially when larger wooden surfaces are to be removed, which can not be spent outdoors, however, a trial with the mild remedy is definitely worthwhile.
Alkaline paint strippers dissolve oil-based paints such as oil or synthetic resin paints (alkyd paints, alkyd paints). These are older paints - so if you want to expose a wood surface in an old house, an alkaline paint stripper could help. Again, a sample at an inconspicuous place about the suitability of the agent information.
However, if you want to treat a wooden wall that was just painted a few years ago, the alkaline paint remover will probably fail because the paint used was a modern acrylic paint that it can not counteract. The most effective but also the most worrying for health and the environment are the solventborne paint strippers which contain solvents such as methanol or dichloromethane. They solve almost every paint job.
In addition to acrylic paint and synthetic resin paint is attacked, even two-component paints can be pickled. The paint remover is applied and dissolves the paint, which can then be scraped off after the contact time together with the paint remover with a spatula.
In addition to the solvents, these strippers contain thickening agents, surfactants and thickeners, which pose a risk to health and, above all, should not be inhaled. Therefore, they are the means that should be chosen only when the other strippers have failed.
Powder, liquid or paste?
The paint remover will be
as a ready-mixed liquid or paste or as a powder which still has to be mixed. Which shape you choose depends on the wood that is to be pickled. Larger wooden surfaces in the horizontal, such as a plank floor, can be quickly coated with a liquid stripper, a drainage of the agent is not to be feared. For detail work on workpieces that must remain in the vertical, such as a door frame, a paste is favorable, which can be pressed well into the cracks. If you are not sure yet when you will be able to find time for pickling, it will be a good way to store it.
work preparation
The instructions for use of the stripper include the instructions for use and the safety guidelines. The rest of the floor should be protected in the vicinity of the wood to be removed. If necessary, the stripper is touched, all tools should be within reach. When working with the paint stripper, eye protection against possible splashes, respiratory protection, a long-sleeved garment and work gloves are recommended.
Whenever possible, the work should be carried out outdoors, if the wood surfaces are firmly connected in a building, good ventilation must be provided. After application, the stripper must act, then it is streaked with a spatula from the wood, the old color is thereby removed. The mixture of paint strippers and paint is one of the hazardous waste that needs to be disposed of in a special disposal process. Mostly a disposal in the depots of the local garbage disposers possible, exact information gives the local environmental office.
alternatives
There are other ways to remove paint from wood except pickling. Old parquet or old planks can be sanded off, there are special floor sanding machines
