• How do I try to remove stains from a MORTEX® with a protection ?

    If there are stains on a MORTEX® varnish coating, they are most probably due to the penetration of dirt through openings in the varnish (scratches, impacts) or to a deficient application of varnish that does not comply with the application protocol of the technical data sheet.
    To identify possible causes and how to avoid them, see FAQ “What are the causes for stains in the MORTEX® product and how to avoid them ?”

    Attempts can be made to clean the stains by means of capillary action exerted by the application of several layers of absorbent paper (see in this FAQ the technique of cleaning by capillary action).

    However, if the result is not satifying, there is, a priori, no other solution than to sand the surface with a diamond tool which will remove the varnish. It will then be necessary to sand the upper part of the MORTEX® coating until the stain completely disappears. A new layer of MORTEX® coating will then be applied, perfectly smoothing the surface of the coating, to avoid repeating the same problem. In certain cases, MORTEX COLOR 2-F2 can make smoothing easier.
    After the MORTEX® coating has dried (see technical data sheet available on www.bealinternational.com), apply the chosen protection according to the technical installation instructions.
    Attention: if you are in a waterproofing technique for a shower, you will have to reapply the missing parts to the system of the two coats of MORTEX COLOR 2-N coating.
