Cromapol is liquid acrylic resin from Cromar Building Projects designed to prevent leaks on your flat or pitched roof. It’s dense in fibres and will cover very small gaps with the application of only one coat of liquid.

Acrylic waterproofing is an effective method that’s designed to permanently waterproof rooftops. Used in conjunction with polyester reinforcing fabric (check our range at JJ Roofing Supplies) it creates a very flexible and durable rooftop covering.

Overall, Cromapol Acrylic waterproofing is suitable for almost any climate, isn’t affected by UV light, and stays durable against air pollution. It’s also environmentally-friendly, as water collected as run-off contains no harsh chemicals and can be distributed into your garden. Lastly, it’s adhesive on most materials associated with rooftops, like asphalt, concrete, metal and wood.

Benefits of Cromapol:

  • Instant Protection, dries fast with no wash-off
  • Reinforced with fibres, stronger membrane
  • Works after just one coat
  • Flexible
  • Cost-effective roof maintenance
  • Fast adhesion
  • White & grey solar reflectivity

Cromapol Acrylic Roof Coating is easy to apply, though it should be applied at a temperature between 5 and 25 degrees celsius. Drying can take up to one week, though this depends on the outdoor temperature and how much of the liquid resin you’ve applied. You can expect the liquid to dry within 72 hours most of the time.

When priming a roof with Cromapol make sure the roof is clean of any debris or dirt and then apply with a roller or stiff brush. The repair patches are simply painted on: Cromapol is a fast and cheap solution to your damaged roof, and you can get effective results with no prior roofing experience. That’s why it’s one of the top choices for DIY home roof repairs.

Materials and Fixtures Compatible with Cromapol

One reason Cromapol is heralded as a great waterproofing solution is that it can be applied on a variety of materials to cover a variety of uses. It can be applied to flat or pitched rooftops (though it is recommended as a flat roof solution).

Here’s a quick list of where and on what Cromapol can be applied:

  • Flat roofs
  • Roof lights
  • Roofing felt
  • Gutters
  • Slate
  • Asphalt
  • Lead
  • Metal
  • Fibreglass
  • Corrugated Asbestos

Cromapol should be used in conjunction with other flat roof maintenance solutions, like felt replacement and total roof renovation. It’s most effective to quickly and cheaply repair cracked flat roofs.

Flat roofs need more regular maintenance than their pitched roof counterparts. This is due to the reduced drainage and the susceptibility of felt of cracking and bursting during the summer or winter months.

You should conduct maintenance on your roof before the change of season: with regular application of waterproofing resin and new felt, you can expect your flat roof to last much longer, from 15 years to 20+ years.
