Product Description

Roc joint PU12 is a concrete expansion joint filler made from polyurethane resin. It is supplied as a liquid, ready to be poured into a saw-cut joint in a concrete floor. Once hardened, Roc joint PU12 supports to the exposed arrises of saw-cut joints, which helps prevent joint arris damage and spalling.

Versatile concrete joint sealant

Roc joint PU 12 is a versatile choice. It can be used for sealing concrete floor joints from 4mm to 30mm wide, both indoors and outdoors – so the same product can be used for sealing saw-cut and armoured joints inside and expansion joints outside.

For new joints, and replacement sealants

Because Roc joint PU12 can be used with so many joint widths, it’s suitable either as a first sealant for the joint, or as a replacement sealant once a joint has widened over time.
Note that Roc joint PU12 should only be used once the floor has been laid for at least a month, to allow the joint to open initially.

Resistant to many substances

Roc joint PU12 is resistant to hydrocarbons and many other chemicals, so can be used in buildings where there is a risk of spillages, or where the floor is regularly cleaned.

Easy application

The joint should first be fitted with Roc Ethafoam joint backing, to provide a firm base for the sealant. Then, Roc joint PU12 can simply be poured into the joint groove, and finished with a hand trowel. Refer to our datasheet for further installation details.

Quick setting

A joint sealed with Roc joint PU12 will be ready for use after just 24 hours – so delays and disruption are minimal.
