    Question: 

    Would this product be suitable to seal the side of a concrete stair case please.

    Answer from Rawlins’ Technical Team: 

    No, this product has been tested for use in movement joints (expansion joints), normally between 2 concrete/block elements, eg wall to wall, floor to floor, or block wall header to concrete floor soffit.

    We have no testing data that indicates this product being used diagonally across a staircase.
