CASE STUDY
There are many good reasons to coat concrete: aesthetics, ease of maintenance, wear protection and as a barrier against water or other contaminants. Without Alocit, new or ‘green’ concrete might need up to 28 days before it can be coated – and moisture in concrete from the environment could also prevent coating adhesion – but, using Alocit, wet or green concrete can be coated straight away.

An example of what this can mean to a contractor is the construction of the Singapore MRT. For this project, pre-cast tunnel sections were to be steam-cured and then coated before installation.
Although the original specification did not include Alocit, the contractor knew that significant savings could be made if delays caused by moisture in the concrete could be avoided. So a system was tested on newly-manufactured sections using the specified top coat but substituting Alocit for the prime coat.
The Alocit system was a complete success, with test results showing full adhesion to the substrate despite the application conditions. Following the tests, Alocit was used to prime coat all the MRT concrete tunnel sections immediately after they were removed from the moulds al lowing significant cost and time savings for the client.
Alocit primers and top coats have also been successfully used elsewhere around the world on green, wet and contaminated floors, culverts, tunnels, bunds and bridges.
