Adhesion decides: why substrate preparation determines service life

In every repair relining we deliberately invest time in a step that nobody sees in the end: cleaning and preparing the surface onto which the lining is applied. This step determines adhesion — and with it the service life of the entire lining.

What our installation teams look out for

• Thorough strip-out: infiltrated old material is not left in place. Whatever is saturated will not carry load and later comes away together with the new lining.
• Complete removal of deposits and slag: especially in flue gas passes and ducts, the actual condition can only be assessed after blasting — which frequently changes the scope of the repair.
• Checking and renewing the anchoring: anchors are wearing parts. No new lining will hold on scaled old material.
• Dust-free handover: fine dust on the contact surface acts as a separating layer — vacuum it off rather than blowing it away, then shutter and cast.
