Existing Concrete and Brick Diesel Bund area was porous and leaking due to prolonged spill contact with diesel during tank filling.
Application
The concrete was steam cleaned and any loose friable material was removed using diamond grinders and hand scrapers.
Due to high moisture content readings M-PRIME 104 – Damp Tolerant Concrete Primer which is suitable for concrete with a moisture reading below 25% was selected to seal the concrete before any coatings could be applied.
When the basecoat was dry enough to walk on, any excess aggregate was brushed off and vacuumed before the topcoat of M-CHEM 100 could applied. The application of the topcoat should be thick enough that the aggregate is slightly exposed (typically 200 microns).
