Frequently asked questions about Mould Release Agents

When should I use a Mould Release Agent?
It is necessary to use release agents when concrete is poured into moulds or onto formliners. The concrete release agent prevents the concrete from "sticking" to the mould allowing easy removal of the concrete from the mould after the concrete has dried/set. 

What types of Release Agents are there? 
There are two types of release agents, either are they reacting in a chemical or in a physical way.  The chemically reacting release agents rely mainly on oil-based liquids, like lubricants, stopping the concrete from attaching to the mould. 
However, with the physically performing release agents the result is the same, but by creating a thin film between that separates the mould and the concrete.

What are WABICON HP and WETCAST-FormFluid HP?
WABICON HP and WETCAST-FormFluid HP are high-performance mould release agents, i.e. release agents developed particularly for high demands, such as easiness of demoulding, maximum protection of the mould/formliner surface or focus on the best concrete surface quality. In most cases, all demands have to be met at the same time. 
And yes, they belong to the “physical” mould release agents. That’s why we don’t call them “mould oils". 

When is WABICON HP used?
WABICON HP can be used for all for smooth, form-finished concrete surfaces.

When is WETCAST-FormFluid HP used?
WETCAST-FormFluid HP is mainly used when making concrete with moulds/forms made of PU, silicone, ABS, coated wood…

What is the best way to test release agents?
We suggest choosing a mould and testing the same release agent, in the same mould, over several days. The first few trials may not give reliable results due to possible interaction with residue on the moulds. The “true” results usually begin to show after the fourth or fifth try.
