Two-component polyurethane binder with excellent UV stability.

Features:

Binder used for creating the TopStone surface based on the mixture of the binder with various types of aggregates offered by TOPSTONE s.r.o. company.

Advantages:

- excellent UV stability - the binder shows resistance to weather,
yellowing and degradation,
- outdoor and indoor use,
can be used for both TopStone marble and river stones

Characteristics:

- two-component binder,
- optimized viscosity - ensures a suffcient layer of binder on the aggregate even at higher temperatures,
the binder doesn't run down, low in solvents,
- suitable for less stressed areas, ie. sidewalks, terraces, surfaces around pools
- the material is flexible throughout its lifetime, it is not suitable for extreme point loads (e.g. narrow legs of chairs and garden furniture)
Slip resistance of the surface can be increased by applying the TopStop microfiller into the uncured surface, or later according to the TopStop material sheet.

Weight ratio of binder components A:B 1,6:1.
The weight mixing ratio of binder and aggregate is 1:20, ie. 1.25 kg per 25 kg (packaging) of aggregate.
