Our client was a very high end private property with a single GRP tank for the boosted water system.  The tank was suffering from gel coat deterioration leading to osmotic blistering with black pin mould growth.

The excess mastic was removed and the internal surfaces abraded to achieve a 75um surface profile to accept the coating.

All joints had a ‘stripe coat’ of DWPU applied, to build up a nominal thickness of 3 – 5mm in these critical areas.  This was followed by a base coat of DWPU applied to all internal surfaces at a nominal thickness of 500 micron.

The above was repeated for the top coat
