Principle of action of the concrete solvent
Once the concrete tool is adhered to a construction tool or decor element, it is closely adhered to the surface, and an attempt to remove it mechanically damages the finish or tool. But you can make a soft blotting by selecting a special substance.
Any concrete solvent contains two main components:
- concentrated acid, capable of destroying concrete;
- metal protection agent and inhibitors.
Acid penetrates into the deep layers of concrete and destroys it, significantly weakening adhesion to the surface. Such softened concrete remains only to be washed off by a stream of cold water under pressure or to clean out manually by a brush. So you can remove all unnecessary layers on ceramic tiles, glass, stone, wood or other material. Exempt from sticking mixer, formwork or metal tools will look like new.
Characteristics of concrete remover
The agent for removing concrete is perfectly safe, it does not form toxic fumes and does not burn. On colored paintwork, it can be used safely - discoloration does not occur. The surface of the metal also remains intact. It has a mild odor that does not irritate the person's airways. In the external environment, it decomposes naturally, without harming nature.
The choice of means for dissolving concrete is quite diverse now. Packed in cans or bottles with a sprayer, which allows to create a foam on the surface to be cleaned. They are all based on organic acids, and you need to work with them roughly as described below.
How to use the chemistry when removing concrete?
The surface to be treated must be cleaned of debris and large pieces removed if they break off. Then apply the solvent of concrete as conveniently, or spray, if it is an aerosol, or apply with a sponge or brush. After applying, foam forms - the product works. It takes a few minutes to stand it.
How much is indicated on the label of the selected solution. Then direct the jet of water under pressure, you can help with a rigid non-metallic brush. If everything is not cleaned out, the procedure can be repeated. Flushing of concrete is available in concentrated form for dilution with water or completely ready for use. It is better to buy concentrate, it can be diluted with water in different ways for different surfaces:
- for old stains - do not dilute;
- for grout and cement coating - 1: 3;
- for lime and paint residues - 1: 5;
- for cleaning after construction - 1:10 with the addition of detergent.
The action of washing concrete on colored surfaces should be checked at inconspicuous areas - apply a small amount and track the state of the decor. Quality glazed tiles can not be damaged, and substandard products can change color.
If in the manufacture of the decor not all technological requirements have been met, this may not be visible to the naked eye. The acid can detect hidden defects. All this applies to wooden surfaces, high-quality varnish can withstand processing, on all other sites it is necessary to try.
Means contain acid, therefore minimum safety precautions should be observed:
- work in gloves;
- to ventilate the enclosed premises;
- should be washed off immediately with water from the enamel.
It is also necessary to strictly adhere to the instructions on the label and do not over-wash it to avoid accidentally damaging the surface being treated.
