Rayson PatchBond TX80
Rayson PatchBond TX80 is a two-component, solvent-free thixotropic epoxy adhesive and repair compound with exceptional sag resistance that bonds and fills on vertical, overhead and even mat-damp concrete surfaces.
ConcreteWalls TDS RY-TDS-902
Best for
Best for non-sag repairs, crack and joint filling, and structural bonding on vertical and overhead surfaces — including damp concrete.
PatchBond TX80 is the compound for the repairs gravity makes difficult. Its thixotropic body holds at 13–15 mm on vertical surfaces without sagging, so coving, joint arrises, overhead patches and bonded fixings can be built in place rather than formed against shutters.
It bonds to an unusually wide range of substrates — concrete (including wet, mat-damp surfaces), fibre cement, natural stone, ceramics, wood, polyester, epoxy, glass, brick and masonry — and hardens without shrinkage into a film impermeable to liquids and water vapour. Quartz-filled testing records tensile strength to concrete up to 15 N/mm² and flexural strength up to 35 N/mm², with excellent impact and good chemical resistance.
Typical duties run from filling voids, cracks and joints to bonding metal profiles onto vertical surfaces, where bonded elements are propped for at least 12 hours while the epoxy grabs.

Quoted after inspection The practical details
Rayson PatchBond TX80: questions people ask
Will it sag on a wall or ceiling?
No — the thixotropic body holds around 13–15 mm on vertical faces at 28 °C without slumping, which is what it is designed for.
Can it be applied to damp concrete?
Yes, to mat-damp concrete with no standing water — the formulation is moisture-tolerant and builds durable bonds on wet substrates.
Why must mixing avoid aeration?
Whipped-in air weakens the compound and leaves voids in the repair. Mix with a low-speed drill for 3–5 minutes rather than a fast one.
How long must bonded fixtures be supported?
Prop vertical bonded elements for at least 12 hours while the epoxy develops handling strength.
When has it fully cured?
Test values reference 7-day curing; check the full cure schedule with our technical team for load-critical work.
TX80 or EM90 — which repair product do I need?
TX80 for vertical, overhead, damp or bonding work where sag resistance matters; EM90 for horizontal floor patches needing maximum compressive strength under traffic.
