When it comes to plastering, success starts long before the first coat goes on. The real magic lies in the prep, and that’s where a reliable bonding agent becomes non-negotiable. Whether you're working on painted walls, concrete, tiles or tricky substrates, the right primer ensures your plaster sticks, sets and stays. And for professionals across the UK, that bonding agent is increasingly Sika Blue Grit.
Why Bonding Agents Matter
Plastering over smooth or sealed surfaces without a bonding agent is like painting on glass it might look fine at first, but it won’t last. A quality bonding agent:
- Creates a key for the plaster to grip onto
- Improves adhesion to difficult surfaces
- Reduces the risk of delamination or cracking
- Speeds up application by ensuring consistent coverage
- Boosts confidence in the final finish
In short, it’s the difference between a job that lasts and one that doesn’t.
