GLOSSARY TERM
Plasticiser
A substance added to paint to increase its flexibility and prevent cracking.
INFO
What it is
A plasticiser is an additive included in some coatings to increase their flexibility. It allows the dried film to bend and move rather than staying brittle.
Why it matters
Flexibility helps a coating cope with temperature swings and minor surface movement without cracking. This is valuable on surfaces that expand, contract, or flex with the building.
Where it is used on a project
Found in flexible and elastomeric coatings used on exteriors, render, and surfaces subject to movement and weather.
How NECC approaches it
Where a surface needs a flexible finish, we specify suitable coatings whose formulation copes with movement, helping the finish resist cracking over its life.
