When is Reinforcing Mesh Necessary?
Updated: 15.07.2026
✓
When overlapping joints, board materials, substrates at risk of movement, and in bathrooms.
Detailed answer
It is essential wherever there is a risk of movement, joint cracking, or differing material behaviour. Typically, this includes old tiles, cladding, OSB, board substrates, joints, corners, and bathrooms. However, the mesh is not a magic solution – it must be properly embedded in the correct layer, especially when applied over existing cladding and tiles.
Common mistakes
- application on dusty or non-cohesive substrate
- neglecting inspection for hollow spots and cracks
- insufficient degreasing and priming
