    Default bond breaker rod

    HI,

    This might be a silly question... Can I use any foam rod to be the bond breaker rod in the shower and bathtub? or is it a specific type?

    THanks

    Depends. The foam should be compatible with whatever waterproofing system is going over it. Some of the waterproofing coatings smell an awful lot like polyester resin, which can dissolve some plastics (expanded polystyrene would melt before your eyes).

    Default bond breaker rod

    I was under the impression that these days Bostik or Sikaflex sealant is commonly used as the bondbreaker.

    Commonly refered to as 'Backing Rod' very cheap and reliable.
    Make sure the prevents any of the waterproofing getting behind it.

    The above is more commonly used on wall sheet joints prior to waterproofing.

    Good luck

    Our guys use Sikaflex, foam rod is to fiddly to work with, silicon will get tight into the corners junctions.

    Alternative is to use a tape with inbuilt bond breaker.

    Gripset have released a non trade version of their product (non trade just means it is a blue colour not grey and in a retail packet available from bunnings)

    The have internal and external premade corners with built in bondbreaker, and jointing bandage with bondbreaker, the internal corners are very good for the DIY as you cannot muck up the most important join in the shower recess.

    The 'Bond Breaker is installed at the wall to floor interface and provides for a bit more movement that sealant alone.

    Good luck

    are bonding tape and backer rods required for renovating a bathroom in a upper level of an apartment block? and when going around corners should I bend the rod around the corner or cut it so instead of one long rod you have 2 short rods. (might seem like common sense but it is the first time I do a renovation.

    Thanks

    Bond breakers are only required inside the shower, being a multilevel building you need to seal the full floor and install puddle flanges in wate pipes, (shower and floor wastes). Bond breakers inside showers are cut to length for each wall and butt jointed at corners. Note; take care when placing the tape over the backing, the object of the tape is to prevent any material getting into the bond breaker area. Start by running a bead of sealant around the floor wall joint, then cut and stick the backing rod to the corner with butt joints, let this cure hen tape over. Good luck.

    Bondbreakers are required when 2 planes meet.Not just the shower recess/ ie wall and floor flashing and the joins of sheeting and panels.

    There are many different types of bondbreakers depending on the class of waterproofing.
    Always use the type of bondbreakers recomended by the waterproofing product you are using.
    Failure to do so may cause the waterproofing to fail and the warranty by the manufacture to be void.

    Make sure your waterproofing is compatible with the adhesive your using (use the same brand)

    regards

    Can yuo explain "class of waterproofing"

    Also a backing rod type bond breaker would be a bit of a chellenge if applied to a floor wall interface outside the shower?

    Google Class 1 waterproofing membrane , then 2 and 3, all will be revealed

    Backing rod is primarly used with class 1 membranes.
    Use the bondbreaker the manufacture advises

    Would you use a type of bondbreaker that wetseal hasn't recomended or tested with ? I doubt it .

    Just as hard inside the shower too, with the membrane over the screed. Every job would have a compulsory cove tile to cover the bondbreaker joint with backing rod.
