Stripping of paints

The stripping of the paint sometimes accumulated in successive layers, then becomes indispensable, if only for a question of hanging and holding without speaking of the aesthetics removed from completely saturated moldings. It is then necessary a concentrated mixture of hot water and washing Saint Marc to come to end and especially to rinse well with clear water before letting dry. For beams, whatever the stripper, it must have the consistency of a gel or glue to adhere to the support to be stripped, produce its effect and thus, not to flow everywhere. If you use a liquid cleaner (soda lye) add a little powder paper glue, it will thicken it and allow you to work more efficiently. The use of a commercial chemical stripper also gives good results, with manufacturers offering significantly improved products. Obviously, wear gloves, painter's cap and glasses.

Paint stripper preparation

Paint stripper preparation

1. You will find in the specialized stores many strippers which allow to quickly eliminate the paints and varnishes on all the surfaces, and to expose the funds. These products act without altering or blackening the woods, and without tarnishing the metals. You can still buy these strippers even if you do not have very large areas to treat because they have other uses (cleaning tiles, for example).

2. It is essential to expose the bottoms in the case of very peeling paints. Apply the stripper by brush, in thick layer, on about one square meter. Do not forget to protect your hands with rubber gloves; take care to splash in the eyes, and moreover, the product giving off troublesome fumes, work in a well ventilated room.

3. Leave the product to act for a few minutes. When the paint is blistering, scrape with a flip-off knife; the paint is easy to remove. A hard brush will be used to scrape the woodwork and moldings faster. To strip several layers of paint, it is usually necessary to make a new application. Collect all waste produced in a container to dispose of it in a dump.

4. Continue the application for the rest of the surface to be treated. Note that the same results can be obtained with a mixture of Saint Marc's laundry, water and flour (it takes about 1 kg of laundry for 10 liters of water and 1 kg of flour). With the paste obtained, brush the surface to expose. It is a stripper less powerful than the industrial strippers, which must be allowed to act longer (almost a night). However, it gives very good results on poorly adhering paints, or for delicate work.

5. Rinse thoroughly, changing the rinsing water every time, since all traces of stripper must be removed; the new paint layers may be damaged by the product. On metal parts, remove all traces of rust with a wire brush or emery cloth (for larger surfaces, use a rust remover).

It is possible to strip some painted surfaces, metal parts or woodwork, by burning, with the soldering lamp but only if the wood is to be repainted. Equip the spout with a flat tip, and aim the enlarged flame at the surface. The heat softens and blackens the paint, which is easily removed. Be careful not to burn the wood! Sand with coarse sandpaper, and clean to remove lampblack. This type of treatment is to be performed with all the necessary precautions for protection and ventilation!
