Zinga Trouble Shooting Guide

The trouble shooting guide below will help ensure you get the correct and best application of Zinga.

Often this is due to to the incorrect solvent being used for thinning. Zinga must be thinned with Zingasolv. Start again with fresh Zinga mixed with Zingasolv.

It is possible to apply a fresh coat of Zinga on an old coating provided it is clean to a SA of 2.5. If this is not the case, re-blast the surface prior to adding the new coat.

This is likely because the Zinga has not been thinned correctly. Use 5-10% Zingasolv depending on whether full or mist coat.

The product has likely been applied too thickly or not thinned correctly. Clean the affected area. Dilute the Zinga with Zingasolv and apply 2-3 thinner coats.

If more Zinga is being used than your calculations suggest, it may be that the blast profile is too deep or incorrect for the type of treatment required. Check the surface preparation page for more information.

If you are using less Zinga than your estimates, it is possible that it has been over thinned. Add the over thinned Zinga to a new tin and mix.

The Zinga is probably too thin. Add the thinned Zinga to a new tin to obtain the correct consistency.

It is likely that the surface has not been blast cleaned to the correct profile of 60 µ Rz. The surface must be cleaned with strong detergent, steam lance or Zingasolv, and re-blasted.

The surface must be clean and blasted to the correct profile. Cheesy texture tends to appear when the Zinga has been applied over oil or grease. The area must be cleaned and re-blasted.

The original surface has not been sufficiently prepared to provide a key for the Zinga. Re-blast the area and check the profile is 60 µ Rz.

It is likely that the HDG steel work was too new to be over coated. Before treating with Zinga, all passivation must be removed and blasted at a pressure of 60psi.

If when viewing the coated steelwork, the finish appears patchy then it is likely that the Zinga has been over thinned, or the blast profile is too deep. Check the Zinga to Zingasolv mix and apply more coats. If the issue is significant it would be advisable to clean the area and start afresh.

This is caused by solvent entrapment and means the top coat on the Zinga is too thick. Remove the topcoat, and if appropriate the Zinga and re-apply at the correct DFT.

Alkyd enamels are not compatible with Zinga. For areas that are to be over coated, a tie coat must be applied of either of Zingalufer (alufer N) or a water based primer – it needs to be touch dry in 20mins. The tie coat must be applied as a mist coat then a full coat. Any top coat can be applied such as a cellulose paint.
