Jointing with synthetic resin based paving joint mortar brings a shine to the surface. The synthetic resin film creates a wet look.
Note should be taken, that after nearly all jointing using synthetic resin paving joint mortars, a very thin synthetic resin film remains on the stone surface and intensifies the color of the stone, resulting in a gloss effect (wet look).
Depending on the type of product or stone used, more or less colour enhancement is given. The synthetic resin film along with the colour intensification disappears from the surface in open weather and through abrasion in the coming months.
This aspect of synthetic resin jointing of paved stones should be discussed with the client in detail before jointing is carried out.
The synthetic resin film makes the stones look wet. In order to show this effect, wet the stones beforehand to see what they will look like after jointing. In case of doubt, always lay a sample surface first, that can be used as a reference surface. The synthetic resin film disappears through mechanical loads and weathering over time.
On heavily trafficked surfaces (roads, carparks) and public surfaces (market squares, train stations), the synthetic resin film usually disappears within a few weeks. This is due to natural weathering such as sun, rain and snow, as well as from the heavy mechanical loads and abrasion.
The disappearance of the synthetic resin film can take varying times. Surfaces that are level and that generally have heavier loads and stronger weathering effects, will lose the synthetic resin film quicker than on edges, that generally lie lower and are not affected so much by loads or weathering.
The intensity of the colour enhancement depends on the product used. The intesity of the synthetic resin film can be reduced, when pre- and subsequent wetting is carried out before jointing.
