    SEALS DAMP

    Our unique pliolite formula seals damp patches and prevents penetrating damp from pushing through and spoiling your décor. You’ll see impressive results in just one coat but we usually recommend applying a second coat for maximum coverage and protection.

    Ready for use on damp interior wall surfaces including brick, concrete, cement and plaster (not breeze blocks). Our paint can also be used as a damp proofing primer/ sealer prior to over-painting or can be left as a finish in its own right. Simply remove any loose or flaking paint or wallpaper and apply to the affected area using a paint brush or roller.

    Coats will be touch dry within 2-3 hours, so you can be stain-free with beautifully painted walls in next to no time.

    Application

    Preparation

    Remove any wallpaper with a scraper or, if the wall is painted, sand off any loose or flaking paint.
    If there is mould, tackle it with mould killer otherwise, use a cloth and white spirit to wipe down and clean the wall.
    Remove as much of the old paint as possible by thorough scraping and wire brushing.
    Avoid the inhalation of dust.
    Wear a suitable face mask if dry sanding.
    Special precautions should be taken during surface preparation of pre 1960s paint surfaces over wood and metal as they may contain harmful lead.

    Application

    Stir well before use.
    Use a roller or brush to apply it to the affected area.
    If it’s only a small damp patch, paint at least 30cm around the area so the damp won’t creep elsewhere.
    2 coats are normally required, allowing a minimum over coating time of 16-24 hours.

    Finishing Up

    Touch dry in 2-3 hours.
    Apply second coat of DampSeal after a minimum of 16-24 hours.
    Drying time can be extended at lower temperatures.
    Clean all equipment with White Spirit.
    Keeps for up to 2 years if stored correctly in an unopened container.
