GftK’s vdw 815+ Epoxy Paving Joint Mortar - Buy Now

GftK's vdw 815+ is an advanced, high performance Epoxy Paving Joint Mortar that is most widely used for larger format paving (generally means flags and slabs more than 400mm x 400mm), with narrow joints > 3mm wide, and light to medium traffic loads, such as natural stone and external porcelain, on both domestic and commercial patios and terraces, swimming pool surrounds and/or retail shopping and other commercial areas. GftK's vdw 815+ is also a very useful solution to repointing smaller format paving such as stone setts that were originally butt-jointed, but now have 3 to nmm joint gaps for example. This is in order to help stabilise the surface, prevent weed growth and make cleaning easier e.g. by jet washing.

GftK's vdw 815+ Paving joint mortar consists of epoxy resin pre-coated, alluvial (rounded), graded quartz sand that is mixed with a special reactive epoxy hardener to produce a free-flowing and self-compacting paving joint mortar. That is wet-slurry applied with lots of additional water, for high performance and extremely durable pointing / grouting in narrow joints (> 3 mm). It is designed for use with natural stone and is also especially suitable for use with quality external (>20mm thick) porcelain tiles and reconstituted stone flags / slabs.
