High volume solids
High volume solids compared to traditional polyurethanes result in lower VOC (volatile organic compounds) per litre, making it a modern solution with low environmental impact.

Hardtop XP displays very good flow properties, and is our true all-round polyurethane topcoat for marine and protective structures.

Hi It says airless spray on hardtop xp? Can it not be sprayed using a normal air compressor ? Along with jotamastic 90 as a primer? Cheers


Airless spray is preferred for Jotun Hardtop XP but air spray equipment can be used (see Application Guide for details - this can be downloaded from the 'Download' section on the product page). Jotun Jotamastic 90 can only be applied by airless spray.

Question: Can you please provide a recommended maintenance cycle for the Hardtop XP two pac topcoat applied to Jotun Intumescent paint system in an external environment ? Thanks

There are several corrosive categories (ISO 12944-5, see table below) we have to consider when offering such advice. In different environments the coatings will have different durability. Applying two coats of Jotun Hardtop XP instead of one would also increase the life expectancy.

We normally suggest that the coating system should be inspected after 5 years and any remedial damage repaired. Equally if damaged in service we would strongly recommend urgent repairs. An undamaged coating system can last for up to 15 years assuming regular maintenance.

Corrosivity Category Building Exterior Building Interior
C1 Very Low --- Heated buildings with clean atmospheres, .g. offices, shops, schools and hotels.
C2 Low Atmospheres with low level pollution. Mostly rural areas. Unheated buildings where condensation may occur, e.g. depots, sports halls.
C3 Medium Urban and industrial atmospheres, moderate sulphur dioxide pollution. Coastal areas with low salinity. Production rooms with high humidity and some air pollution e.g. food processing plants, laundries, breweries, dairies.
C4 High Industrial areas and coastal areas with moderate salinity. Chemical plants, swimming pools, industrial and coastal.
C5-I Very High Industrial Industrial areas with high humidity and aggressive atmospheres. Buildings or areas with almost permanent condensation and with high pollution.
C5-M Very High Marine Coastal and offshore areas with high salinity. Buildings or areas with almost permanent condensation and with high pollution.
