FS MASTIC LIQUID is a two-component adhesive formulated with unsaturated polyester resin in styrene and reinforced with mineral fillers. It is intended for bonding natural and artificial stones.
Its fluid consistency effortlessly fills extensive surface areas and cures to a clear, high-strength finish within hours. Use 1–4% hardener by weight, keep layers no thicker than 2 mm, and note it may yellow slightly outdoors.
How to use
- Make sure the surface is clean and lightly abraded
- Add up to 5% polyester colour paste if you want to tint it
- Mix 1 to 4 g of soft hardener per 100 g of mastic and blend thoroughly
- Apply in layers no thicker than 2 mm; for deep holes, corners and edges, use less hardener to limit heat build-up
- Work or process the surface after 6 to 8 hours
| Mixing ratio | Hardener ratio 1 to 4 g per 100 g of mastic (1 to 4% by weight); more than 4% weakens adhesion and surface curing |
|---|---|
| Drying and curing | Usable for about 8 to 15 minutes after mixing (3 to 5 minutes at 4% hardener, 20°C); can be worked after 6 to 8 hours |
| Application temperature | Warmer conditions speed up curing and cooler conditions slow it; below 5°C with less than 1% hardener, curing is much slower |
Before you start:
- Wear chemical-resistant gloves
- Does not protect against strong acids
- Joints exposed to frequent moisture or frost have limited long-term durability
