• How to remove protection applied by impregnation (oil-repellent REPELOIL) from the BEALSTONE® coating?

    If for any reason (e.g. changing the colour of the coating or carrying out a repair) it is necessary to remove this oil-repellent aspect, the best solution is to remove it mechanically (provided the oil-repellent is completely dry) by abrading the treated surface with a diamond disc (grain size between 100 and 150).

    (You can go directly to point 3 if the oil-repellent is very hard).

    1. Clean the surface with turpentine and a white cotton cloth to remove as much oil-repellent as possible.
    2. Use a vaporetto style steam cleaner to try again to remove as much oil-repellent residue as possible.
    3. Abrade/sand the surface so that there are no oil-repellent residue left.
    Please note that if any traces of oil-repellent remain, the varnish will not adhere to these areas, and the shower will not be waterproof. It is therefore necessary to make sure that everything is removed, which is a rather delicate operation.
    4. Vacuum and clean the surface thoroughly to remove all traces of dust.
    5. After complete drying, apply the chosen protection according to the method recommended by Beal.
    Reservation: after point 3, traces of well dried and hardened oil-repellent may remain throughout the surface. The varnish should in principle be able to stick to it, but we have no test in this respect.

    If the BEALSTONE® product is structured and not perfectly flat, it will not be possible to remove all the oil-repellent from the small cavities without attacking the last layer of BEALSTONE® product.

    We therefore recommend abrading the entire surface until a perfectly flat surface is obtained, without open pores.

    The abraded surface and the direct environment must be cleaned and dusted thoroughly.

    The surface will be treated, according to the installation protocol, with the chosen protection.
    If fresh oil-repellent is present, tests can be carried out with turpentine.
