Most adhesives slow a job down more than people like to admit.

Waiting on set times.
Holding materials in place.
Planning around downtime instead of progress.

And on a busy site, that adds up quickly.

That’s exactly why we’ve launched Epoxy Adhesive Rapid.

⏱️ Sets in just 10 minutes
💪 High-strength structural bond
🌧️ Works in damp conditions
⬆️ Suitable for vertical and overhead applications

Built for real site conditions across:
Concrete, steel, masonry, and more.

Used for:
• Fixing and anchoring
• Structural repair
• Crack filling
• General construction applications

Less waiting. More getting on with the job.

Hot weather on site changes more than people think.

You can feel it the moment you start working, mixes behave differently, working time drops, and everything tightens up faster than expected.

If you’ve worked in it, you’ll know what I mean. A job that felt straightforward in the morning can become a race against the material by the afternoon.

That’s usually where issues creep in, not from the work itself, but from not adjusting to the conditions early enough.

The skilled teams don’t just push through it. They plan for it. They slow down where needed, stay ahead of set times, and make sure the system they’re using is working with them, not against them.

That’s why product choice matters.

Larsen screeds, mortars and adhesives are designed to perform consistently in real site conditions, helping keep control when temperatures rise.

Because good finishes don’t come from fighting the conditions on the day.
They come from being ready for them before the work even starts.

Most callbacks are avoidable.

Not all, but more than people think.

It’s easy to blame the tile.
Or the adhesive.

But most problems start earlier.

Dust.
Weak substrates.
Corners cut during prep.

The job looks fine at first…
until it doesn’t.

The best installs are built before the first tile goes down.
