    Default Stopping up joins in bathrooms

    Hello All,

    When stopping up joins in villa board, that will be under tiles, and in wet area plaster board, is normal base coat and top coat used? or is there specific type for wet areas?
    Also if normal base/top coats, does water proofing go over it ok? I know some tile adhesives react with some types of water proofing so thought I'd check!

    Cheers

    I'm not sure if it's common practice to use it but there is certainly wet area specifc base coat. I've used it in the past and recall it is very hard to sand, so don't go overboard!

    Just base coat is common practice, this gets waterproofed after drying and sanding.

    Also if normal base/top coats, does water proofing go over it ok? I know some tile adhesives react with some types of water proofing so thought I'd check!
    Never seen a problem with tile glue reacting with waterproofing, only problem I ever saw was a bloke used premixed glue in a wet area, so would not bet over the waterproofed areas.

    Cheers
    Good luck and fair winds.

    Thank-you for the replies.

    In a tiled shower area do you still tape in the joins of the villa board before water proofing? Or just silicone the gaps and then waterproof?

    Cheers

    You tape and base coat the horizontal joins. The vertical corner join you fill with a flexible caulk. Then

    fabric tape and waterproof over

    Bout 99% of all new home builders in Qld simply tape and base coat the wall joints.

    If you want to caulk/seal the wall joints, it's about the oly place I advise people to a Silicon based sealant, because if there is movement, the non stick property of Sil1con will allow the membrane to move rather than break.

    Another question!

    With external corners in villaboard, that will be tiled over, such as edges of set in shelves or ends of dividing walls, do I base coat with external beading? or just fill with sikaflex?

    Cheers

    We usually put an external on full length corners but not on the shelves.

    Just use normal plasterboard clouts is best. Self embedding screws don't always self embed!! Yes one coat of basecoat over them.

    Normal base coat in wet areas may go mouldy over time so it is recommended to use Wet Area Base Coat

    Be easier and cheaper to just apply extra waterproofing over the joints, but interesting for mould to take hold in such an area.
