Jotun Hardtop CA has been developed for application on top of Jotun epoxy base and mid coats. Hardtop CA will retain a high gloss finish in rural C1 environments and through to municipal and industrial atmospheric conditions contaminated with sulphur dioxide C3. Additionally, Jotun Hardtop CA is also ideal for C5-M coastal and offshore marine environments that are exposed to atmospheric conditions with high levels of salt.


The Jotun Hardtop range should be applied using an airless or conventional spray. Jotun Hardtop CA can be applied by brush but it is recommended that this is limited to stripe coating or small areas. With a theoretical coverage rate of 8 square metres per litre, Jotun Hardtop CA offers great coverage and is available in 5 litre tubs.

Jotun Hardtop CA is designed for use in outdoor environments. With excellent protective properties, Jotun Hardtop CA is ideal for use in marine and highly atmospheric environments. Incorporating excellent water resistance and non flaking properties, Hardtop CA works well when exposed to harsher conditions.
