Regular price Excl. VAT: £41.00 Incl. VAT: £49.20


Reprotec Joint Doctor is a coloured, two pack, pourable, flexibilised Epoxy sealant. The consistency of the mixed sealant allows direct pouring of the sealant into horizontal joints.

Reprotec Joint Doctor is hard and tough enough to protect arris edges from heavy wheel loading, but possesses sufficient flexibility to accommodate a degree of movement (10% of the joint width).  Reprotec Joint Doctor is particularly suitable for filling saw cut joints in long strip floor construction.
