Features and Benefits
RonaDeck Ultra Bound is a two component polyurethane resin which binds kiln-dried aggregates to produce a UV stable, SUDS compliant permeable surface. RonaDeck Ultra Bound provides an attractive porous surface which is strong enough for foot and light vehicle traffic.
RonaDeck Ultra Bound is designed for use on pathways, patios, driveways, pool surrounds. Whilst RonaDeck Ultra Bound is supplied pre-catalysed, additional catalyst may be added on site. A guide on adding catalyst can be provided.
