Description
Selleys FlexiSeal (ProSeries) is a high-strength, fast-curing polyurethane sealant and adhesive built for tough construction jobs. It seals and bonds expansion and construction joints in both vertical and horizontal applications, staying highly flexible once cured so it can absorb the natural movement of a building without cracking or pulling away. This 600ml grey sausage pack suits a standard sausage gun and is ideal for larger trade and DIY jobs.
Key features
- High-strength, flexible grey polyurethane adhesive and sealant
- Handles up to ±25% joint movement
- Non-slumping, low-modulus formula
- Fast curing and weatherproof for indoor and outdoor use
- Paintable after cure with no primer needed on most surfaces
- Excellent adhesion to most common building materials
Where to use it
Bonds and seals most building materials including concrete, brick, masonry, ceramic tile, metals, softwood, hardwood and some plastics. Suitable for indoor and outdoor sealing of expansion and construction joints, around window and door frames, and general weatherproofing.
How to use
- Prepare joints so they are clean, dry and free from oil, dust and curing agents. Use a backing rod for deeper joints.
- Cut the nozzle, load the sausage into a suitable gun and extrude the sealant, ensuring full contact with both joint sides and avoiding air entrapment.
- Tool and smooth off with a spatula.
- Once fully cured, paint if required using water-based paint. For solvent-based paints, undercoat with a water-based primer first.
Important notes
- Applies and cures best at moderate temperatures (around 20°C), especially in cold weather.
- Will not adhere to PE, PP or PTFE; test other plastics and rubber before use.
- Not recommended for continuous submersion or below-water-line use.
- Not ideal over old or incompatible sealants, which may affect cure.
