Concrete Drainboard Groove Molds, Reusable Rubber

Concrete Drainboard Groove Molds, Reusable Rubber The cleanest most modern look for a drainboard is made with these mold pieces- Create drainboard grooves right off the surface of the finished concrete counter.  Sloped molds create a sloped channel in the concrete, so any water will head towards the sink! Made of industrial grade polyurethane rubber, fully re-usable trivet rail form molds.
