LTA Directional Signs

When the LTA directional signs were initially erected, a 3-coat system was applied and unfortunately it had failed due to creeping and crevice corrosion. The SATBlast Vapour Blasting Machine was deployed to remove the old coatings from the structure; where after proper surface preparation (SA 2.5) was achieved efficiently and effectively. Zinga was then applied on it with a 15 year warranty against corrosion.
