In garages, workshops or cellars, the screeds left in raw cement, once dried, have a major disadvantage. They generate dust. In addition, untreated and unprotected cement is an absorber of all kinds of stains because of its porosity. Painting this type of soil avoids these disadvantages. You can also paint floors and bring a new and original touch. This decoration, which is more common in Belgium and Holland, is still not widespread in France among the general public. However, it renews the interior and opens on a design spirit, perfectly adaptable with contemporary furniture and can highlight harmonies of warm colors.

Paint a cement floor
1. Whatever its condition, the cement floor should be prepared before receiving a paint. If the soil is new, dry, clean and has a very smooth appearance, a complete dusting (vacuuming, preferably) may be sufficient. In case of old floor of a workshop or garage, it is essential to treat stains with a brush, with a degreasing solvent (trichlorethylene or specific product for garage floors).
2. If the soil has some holes or cracks, seal them with synthetic putty. But if the surface seems more degraded, do not hesitate to make a patching.
3. A cement floor may also have been covered with a bonded coating. After torn off the substrate, treat the remaining glues or coatings. You can either apply a powerful stripper for these operations, or burn torch residue. In both cases, ventilate heavily (or wear at least one light mask).
4. After patching or after treatment of the old coat remnants, sand the entire surface with a special corundum sanding stone. This operation, if it generates dust, makes it possible to obtain a perfectly flat and smooth floor. Ventilate and finish by vacuuming.
5. Paints used to paint cement floors or parquet are generally based on epoxy resins or polyurethanes. These long lasting paints, which are waterproof, have a very good resistance to wear and solvents.
6. It is advisable to pass a first layer more liquid than the soil will absorb in part to constitute a solid grip. Let dry and spread out the next two layers, pure past.
Paint a parquet floor
1. If it is a question of painting a floor (supposed old), proceed first to dusting and especially between the boards. Re-seal slots that are too wide or too deep, reclose loose blades, the goal being to obtain a stable floor for patching. In the case of waxed or varnished parquet, use a suitable powerful stripper or stripper, respectively, as floor coatings such as glazing agents are often based on polyurethane resins. You can also sand it.
2. If the floor is really dirty and it may affect the adhesion of the cement, you must either sand it or clean it with Saint-Marc laundry. Rinsing the soil and drying (several days) will then be required before proceeding to patching.
3. On a dry, dust-free and degreased floor, spread the patch that you have prepared in sufficient quantity for the room. Revisions are not recommended. Spread the product with a trowel. You will need to get a layer of one centimeter thick. It is therefore necessary to count 7 liters of water for 25 kg of powder to obtain a Kg of product per m2.
4. If you can paint directly on the cleaned surface of a wood floor, take advantage of the blade guide to obtain original effects. Rather than getting a uniform, single-color surface, use several colors that you will apply alternately. Delineate the surfaces to be painted with plain marking tape.
5. Always start with the lightest shade between the bounding strips. Allow to dry beyond the recommended time to be able to rest the marking strips on this painting without risk of damage (hanging during the removal of the tape).
6. Now arrange the adhesive to border the surfaces to be painted with the other, darker color. For both shades, use fairly wide flat brushes (width of the floorboard if possible) to avoid too many times.
