Before the advent of DIY superstores (GSB), materials and accessories for DIYers were distributed mostly by hardware and druggists (also known as color dealers), two species of traders completely disappeared from the surface of our cities. The drugstore products were rather liquid products (chemicals, glues and varnishes, paints) although the wallpapers, the sticks of frames and others could also be there. The hardware store sold in particular tools, large and small and all the nails, screws and bolts to the piece or weight. Everything is now gathered under the biggest DIY brands.
1. Many jobs (bonding, coating, painting, dilution, brazing) require the cleaning of the surfaces of the workpieces. of the so-called chemical products, by their different natures, fulfill these functions. They are unfortunately almost all dangerous and are to handle and store with the utmost care. Our era, which is beginning to worry about their use, recommends to use them only in the form of "substitute" and tends to limit the use and control the polluting evacuation in the various networks. Their use in well ventilated premises is therefore particularly recommended as well as the wearing of gloves adapted for their handling.
2. The trichlorethylene which is now only displayed with the word "substitute", is a powerful degreaser whose inhalation causes nausea, headaches that can lead to loss of consciousness and whose contact on the skin can cause attacks similar to frostbite. Like many of these chemicals, they are generally presented in containers of the appropriate plastic liter or glass for so-called household quantities.
3. The alcohol to burn (or denatured alcohol), well known to housekeepers, is a less dangerous degreaser than the previous one. Its use requires however some precautions especially in the presence of a flame or a fire in the open air since, as its name indicates it, it is highly flammable. Many barbecue accidents are due to his inconsiderate use.
4. The white spirit, a basic thinner for glycerophthalic and polyurethane paints and varnishes, is also used to clean brushes (before they are dry) used for these paints or varnishes. Moreover, it is a heady product and moreover, very flammable. If it can only cause headaches, it is even more embarrassing to bear if a gas appliance is put into operation: the mixture of the vapors it releases and the burnt gas is extremely unpleasant and harmful in case of exposure prolonged without aeration.
5. Gasoline (de) with turpentine, also flammable, is fatter than white. She is also less unpleasant to breathe. Its main use is in the form of mainly wax diluent and varnishes. Cabinetmakers are great users.
6. acetone is an effective thinner on products based on polyurethane and neoprene (glues and varnishes). Very dry and therefore very volatile, this product is also easily flammable.
Beware of media (especially painted) that it may attack when used as a glue diluent (labels). Do some preliminary tests.
7. The species "A", "C" and "F" are cleaning or dilution products depending on their volatility. Hydrochloric acid, diluted, well known plumbers, is an effective product against limestone that is able to dissolve. It is also very useful for tilers to clean the traces of cement laitance (cement veil on the tiles and cleaning joints).
