Cromapol is ideal for use on a wide range of surfaces, including flat and pitched roofs, roof lights, flashings, fibre cement sheeting, gutters, slate, asphalt, lead, metal, and primed roofing felt.
Application Instructions
Before applying Cromapol, ensure the surface is clean, dust-free, and free of debris. Remove all moss, lichen, and plant growth using AlphaChem Fungicidal Wash, paying special attention to corners and gutters. The area to be repaired should be free from standing water. Repair any cracks, splits, small holes, or flashings, and for gaps or expansion joints larger than 3mm, reinforce with Glass-Fibre scrim and Cromapol prior to full coating. While Cromapol can be applied to damp surfaces, for best results, application to a dry surface is recommended.
Cromapol can be applied easily using a brush, roller, or squeegee. Application temperature should be between 5°C and 25°C. Drying time varies up to one week, depending on temperature and coating thickness. The coating may remain soft during this period, but this does not affect its waterproofing performance. For detailed application instructions tailored to specific surfaces or uses, consult Cromar Building Products.
Please note: These instructions are for guidance only and do not guarantee product performance. While every effort has been made to ensure reliability, Cromar cannot accept liability for any loss, injury, or damage resulting from use.

Brilliant no problems at all, the Crompapol did the trick. Quick Delivery with sound advice given.👌

Unfortunately the product that I ordered was out if stock due to supply issues, however I was offered an alternative, similar product which, whilst being slightly more expensive, the Company offered to me at the same price. Fantastic supplier, well recommended. I will definitely use Sealant Supplies Ltd again.

I can’t comment on this particular product as it was unavailable and I was offered a different product as an alternative, so this is more of a review for the company who managed my order to satisfaction. Many thanks

Although you could not supply the Cromapol, you offered an alternative at the same cost.
You kept me informed of a slight delay whilst waiting for the alternative to be ready to be sent.
You also supplied the alternative in 4 x 5ltr cans which makes it easier to carry and use
Guven (verified owner) –
Disgusting! I was sent a 20L tin that was half full. They then sent me out a 5L as compensation which is the wrong color!! They sent me a black one instead of grey.. this is all after they initially encouraged me to order this seal acryl rather than the cromapol which I know it’s good.
james McKee (verified owner) –
Product fine and does what it says
If I had one issue it would be that when you contact me by email about issues with the order you cannot reply to the sent address and have to faff about with a different address and input the order details
Marius (verified owner) –
Good stuff
Peter Vance (verified owner) –
Originally ordered Cromapol. Was contacted to say there would be quite a wait and was offered alternative,same quality or better. I agreed to accept and got my order quickly. Sealacryl in grey, slightly darker,nice,and a longer shelf life. Very pleased. Hopefully deal with you again.
ManyThanks.
