Some jobs will require coatings to be applied in less than ideal surface preparation standards.
For ST 2 & ST 3 a surface tolerant coating is required.MC Miozinc and MC Prepbond are both surface tolerant primers. Organisations are then advised to technology that has proven outstanding performance to marginal surface preparation:
Excellent surface tolerance Means
No re-blasting because of light or medium flash rusting
No re-cleaning because of high tolerance to salts & chlorides
A comparison test performed by the FHWA (Federal Highway Administration), an organisation that covers the maintenance of more than 3.000 steel bridges, has proven the superior performance of “Wasser ” coatings to minimally prepared substrates. The FHWA tested 2 systems of different suppliers (Wasser being one supplier) applied to A. an SA 2,5 blasted substrate and B. a mechanically prepared substrate. The results were astonishing. The performance on the mechanically prepared substrate was almost equal to the performance on the Sa 2,5 blasted substrate, even when applied to a salt contaminated substrate. This proves the outstanding surface tolerance of Wasser systems to marginally prepared substrates, salts, blistering and still supplying high quality corrosion resistance
