Fan Housing <strong>Repair</strong><br />
Wear Guard Fine Load<br />

Canada Cement Lafarge<br />
Cement Manufacturing<br />
Problem:<br />
Poor fitting ceramic tiles caused severe, uneven wear to this cement fan housing. Ceramic tiles would<br />
become loose <strong>and</strong> break free from the housing substrate. This would cause the fine cement particulate to<br />
wear directly through the metal fan housing.<br />
Solution:<br />
Existing ceramic tiles were removed. Flat exp<strong>and</strong>able metal was tack welded in a raised position 1/8”<br />
above the actual substrate. Tack welding exp<strong>and</strong>able metal improved mechanical bonding properties of<br />
Wearguard Fine Load. Fan housing was then s<strong>and</strong>blasted to a SSPC-SP5 white metal finish. Complete<br />
repair areas were then chemically cleaned using Cleaner Blend 300. Wear Guard Fine Load was applied<br />
at a thickness of 1/2” pressing through the exp<strong>and</strong>able metal, establishing complete contact to the fan<br />
housing surface. Wearguard Fine Load was smoothed <strong>and</strong> sculpted using Acetone. Smoothing Wear<br />
Guard Fine Load following gel point helps to reduce leading edges. To provide a smoother surface <strong>and</strong><br />
protect face areas, Brushable Ceramic was applied to a thickness of 30 mils at two 15 mil coats.<br />
Brushable Ceramic was applied following a 4 hour partial cure of the Fine Load.
