- As a higher-quality substitute for traditional putty in heritage and public buildings, such as canal-side buildings, farmhouses, schools, station buildings, etc.
- As an elastic filler for smoothing/levelling surface damage such as screw and nail holes in glazing beads and other wooden parts.
- Repair putty for damaged seals in seams, based on silicone technology.

Properties
- Durable, retains elasticity, fast moisture-curing.
- Excellent adhesion without primer on practically all surfaces, even when moist.
- Superb workability using a professional caulk gun, due to the special yellow XL spout.
- Easy to shape with a suitable jointing tool (PALU) and/or finishing block.
- Good resistance to UV, weather, water, moisture and ageing.
- Non-corrosive to metals.
- Extremely low-maintenance, does not crack, split, wrinkle or petrify from drying out.
- Compatible in direct contact with edge seals on insulating glass and PVB-laminated glass.
- Isocyanate and solvent free.
- Odourless, adhesive-free, bubble-free and non-shrink fast-curing hybrid system.

Application conditions
- Application temperature (ambient and surface) between +5°C and +40°C.
- On stable, compatible, clean, uncontaminated, grease-free and dust-free surfaces.
- Use a suitable brush to remove any loose particles from the surface.
- Degrease the surface properly using Seal-it® 510 Cleaner.
- Seal-it® 235 ELASTO-STOP has a broad bonding spectrum, but highly porous surfaces should be pre-treated with Seal-it® 520 PRIMER and non-porous surfaces with minimal bonding should be treated with Seal-it® 525 Clean & Bond.
- Minimum dimension of the seam seal (triangular joint): 10 mm x 10 mm.
- Use a professional caulk gun fitted with yellow XL spout, shape using a scraper and/or finishing block.
