Taking care of corrosion on moulds

Corrosion on moulds during concrete production

This is a real issue and something you need to work towards stopping. To do it you need a good idea of what causes the problem initially. The materials you use during concrete production may hold chemicals that affect the mould surface. Such an occurrence happens when your metal moulds are vulnerable to corrosion. It can also happen when you don't clean them correctly.

When the mould surface is set to corrode, your metal can expand as much as seven times. The pressure is influencing the surface of your concrete. This can damage the material. In the majority of instances, people ignore the corroding, allowing it to continue. This does not bode well for the construction process. It is likely that rust stains will keep popping up on the material. As a result the end user has to remove them. This prolongs the finishing and production times.


There are some steps you can take to help prevent this complication. One thing you can try is to purchase some new moulds. Consider using non-corrosive metals like stainless steel or aluminium.

Something else you can try is treating your moulds well to preserve their condition. If you are storing the moulds outside, cover them well. Avoid exposing them to inclement weather because it can cause corrosion.
