Jotamastic 87

The original market leader in epoxy mastic technology. To be applied directly to steel surfaces where good standards of surface preparation (min ST2.0) have been achieved.

Jotamastic 87 gives excellent corrosion protection both in salt and fresh water. Applied at the correct film thickness (150 to 300 microns in a single coat) to properly prepared steel, it is able to prevent corrosion for up to 15 years.

The aluminium range is particularly suited for submerged areas (look in choose colour for Aluminium or Aluminium red-toned). Aluminium flakes within the coatings create an impenetrable barrier to water and increased coating flexibility.

Use the Wintergrade version for application below 10°C and faster curing times in normal conditions.

Pack size including hardner is 4.7 litres  (4.4 litres for the Aluminium or Aluminium red-toned).

Recommended topcoats:

Standard: Conseal Touch-Up

Premium: Hardtop AX

Eco: Hardtop CA

What our customers say

Excellent customer service and competitively-priced products. Their product knowledge is solid and if you have any questions about the application process etc. they are quick to respond with input/advice. Recommended - Matthew Traver - Kent
Thank you for the excellent service and advice I have received From yourselves. I have placed 3 orders recently and have received every one exactly when I was supposed to. Each item has been brilliantly packed - I will certainly be recommending you to all the other boat owners I know. - Paul Andrews - West Sussex
Couldn't be more helpful and professional. The best paint company I've ever used. - Glosstock Sales
Thank you for the exemplary service, the paint tins were so well packed, and the surprise Document Pack, was very helpful. That, combined with very swift delivery, was most impressive - D G & B L Lewis - Cardiff
Thanks, paint just delivered this morning. Excellent service from you and the company. Keep up the good work! - Robert Higgins - Edinburgh
Just a quick note to say how pleased I am with your products. I have just completed painting my boat and I am thrilled with the result. Excellent product and service – cheers - Adrian Mickleson - East Molesey
Helpful, professional and know their products. - John Richards
Great marine paints. - James Crompton
My boat went back in the water today! I would like to thank SML for the great service you provided, both over the phone, super quick delivery, but above all an excellent product. The boat looks great - Steve Duffy - Staines
I used your SHIELD Surface Tolerant Primer and am hugely impressed with the results - this is by far the best result I've had out of many different paints I've tried for this task! The performance is all the more remarkable since the keels sink into highly abrasive harbour mud every low tide, which scours most coatings off. - Mark Hartswood - Scottish Borders
If you require anti fouling paints - Go no where else! I have used all the leading antifoul manufacturers paints over 30 years. CU-PRO is the best on the market, does the best job and even cheaper than most of the others. SML are a quality company and with the best products. - David Rosser
We are very impressed with the CU-PRO anti fouling. Just dried out the yacht after 14 months continuous immersion and the anti fouling had repelled growth very well, delighted with the anti fouling’s performance and will be re-coating with CU-PRO before re launch in spring next year. - Ian Binnie - Argyll
Many thanks for a wonderful service which would be hard to equal, I have never felt more confident in using your company - Thank you - John Parkin - Mexborough
Your website is imho, one of the best in the business. Great products, advice and all the ancillaries needed to get a first rate result, delivered swiftly at a very fair price indeed. Tops! - Tim Allen - East Sussex
Recently used SML to order paint for my dutch barge. All the staff were very helpful and knowledgeable about products. They even managed to get a package sent out to me next day when I had come up short on thinners at the end of a long day spraying. I will definitely order paints from here in future. - Christopher French
I was delighted with your service and am in the process of placing another order i paint boats for a living haven’t had the pleasure of using your product but found it easy to use. - Brian Wholey - Lancashire
Ordered and delivered within 2 working days. Outstanding service and communication. My order from another company who makes for the trade still not here after a month! - David Black - Denny, Scotland
Excellent Company. Very good knowledge of products and can't do enough for you. I have used this company for around 10 years. - Joseph Wiggins
Thank you very much for a superb product. I used Cupro for the second year at June 2019. On 15th May 2020 - after lock-down, I returned to the boat to find a heavy curtain of weed growing in a "slime" of mud on the hull. I brushed off the mud - the weed went with it, and you could believe the boat had been freshly anti-fouled that day. Excellent - a superb product. - Rod Edmunds - Hayling Island
Hello guys, the customer service I received when I was calling for advice really was excellent, I'll be recommending you to all my fellow boaters - Richard Sergejev - Hertfordshire
