• How to treat water stains without the presence of greasy and/or tinted products on the MORTEX® coating?

    • Sand the protection by entering the MORTEX® product until the stains disappear.
    • Allow damp stains to dry. Ventilate the room well and observe the disappearance of the stains.
    • If necessary, apply the missing coats by checking their thickness (by respecting the application protocol in the technical data sheets available on www.bealinternational.com ).
    • Apply the protection in due form according to the installation protocol.
    Never add a protective coating on a stain as this will lock in the stain, preventing its removal later.

    If you only sand the protection, there will always be a risk of having residues in the small cavities of the MORTEX® coating. That is why we advise to sand by entering the MORTEX® product in order to obtain a MORTEX® coating free of any protection.
    Furthermore, if there is still some protection product left in the micro-cavities of the MORTEX® product, you will have darker stains in the places where the old protection has become embedded. You will have the impression that there are two or three coats, whereas you have only applied one.
