Micron Extra2

[Mike k]

This year I decided to do the a/f myself ( Boatyard has done it twice previously but not sure what they used) so contacted Int paints and after a discussion bought and applied 3 coats of Micron extra 2 to the hull and Trilux to the tabs and rudder.

Average speed range 15-20knots .

After a couple of trips the Micron Ex 2 medium blue appears( when looking below waterline) to have paled to quite light blue on the hull and I have noticed more than normal fouling. This may just fall off next time out but cant be sure.

Have emailed Int. paints but wondered if others use Micron extra 2 on their motor boats with similar speed profiles and to what success?

cheers for any input

Mike

Hi mike

Have used micron extra on 2 boats for a few seasons, here's one of them

The other one also is of the same persuasion. I think your boat it far to fast for a fully eroding af. 3 coats of micron extra would last 2 seasons on a sailing boat, now you would think international would know better, but proof is in the pudding.

Btw, 3 coats costs money and time, one coat of cruiser uno would have done.

All IMHO, hope this helps…

Also I believe Micron Extra 2 was new to market last year and may not be as effective as previous versions due to even more stringent eu laws on antifoul constituents. I wouldn't be surprised to hear a lot of boat owners complaining this year when they finally lift and check!

Indeed, the 2 is like the EU version of Uno, we will wait and see, I apply 2 coats to waterline, rudder, keel and bow areas, single coat for the rest and have had good results on boats that top out at 9 knots with a good following blow. We will see how the update is at the end of the season.

I used micron last twice out. Get 18 months on fly bridge solent based. When power washed the coating left comes off so no build up and easy prep for next one coat. Stripe coat at waterline and navy stays navy until dry when it lightens considerably

I'm using Micron 2, but only been in the water for a month and about 10 hours of motoring at 20 knots. So far so good.

I think you need to find an effective a/f for your area, accept that year to year can change, the right one for your speed and given the whole damn hassle, buy something at the top of the range. Whats is the price difference.. fifty quid or so. Ask the boatyard.. they lift the damn things out.. they may not know who put what on, but they just might tell you who came out pretty clean that year, in your marina.
I use Trilux all over and it seems .. remarkable... whether it is that good everywhere, I dont know.

May I suggest you read this the datasheet for Micron Extra 2
http://www.yachtpaint.com/gbr/diy/products/antifouling/micron-extra-2.aspx

Suitable for high speed craft
No

It is quite usual for the colour to change from the applied colour when immersed - normally paler

If the average speed was 10knts or so, with the odd burst at 20 I would say it was the right choice on the self polishing antifouls. If the continual speed is between 15 and 20 I would opine that it is not

However that would not effect the situation so soon, as it simply means that the active surface is refreshed too quickly and the time element of protection is reduced

There is little doubt IMHO that the new EU regs regarding the solvent content will effect the efficiency of antifouling but mainly I think in relation to its application conditions - which if correct - will not I believe have a adverse effect on its efficiency.

Finally I am amazed that International would make a recommend for any of their antifouling without them knowing what it was being applied over

Boatyard has done it twice previously but not sure what they used

unless of course they pre-empted their advice with a suggestion that Primocon was applied first

If old antifouling is incompatible or unknown, seal with suitable barrier/sealer coat.

I have used both Micron Extra and Micron Extra II on Flower Power, cruising speed is 20-24kts depending on conditions, and it works just fine.

It's probably not the best choice for a 50kt+ RIB or race boat.

Well I retract that part of my post as I have now found this

•High performance, premium multi-season copolymer antifouling, providing up to 2 years protection even in the harshest fouling conditions.
•Polishing action ensures that a fresh, active layer of antifouling is always exposed to the water
•Multi-season lifetime (3-4 coats) giving you the convenience to haul out, wash and re-launch without repainting every season
•Biolux Technology that allows Controlled optimised biocide release for sustained antifouling protection.
•Wide over coating window - can be applied up to 12 months before launch meaning you can apply antifouling in the autumn, launch in the spring
•Suitable for high speed craft up to 25 knots
•NOT suitable for aluminium /alloy substrates or zinc sprayed surfaces.
•Please note: Final colour will develop on immersion; I.e. White antifoul when applied may look slightly grey. Once immersed it looks white.
•Colours: White, Blue, Green, Navy, Red, Dark grey, Black
•Coverage: 9 sq.m/Ltr
•Thinners: No. 3

However as I said just a few trips would not - in the craft in question - providing all else is OK - effect its efficiency.

The problem has always been for years - the water you are in - what works well for instance in the Menai where I am berthed MAY be very poor on the East Coast for instance.
Indeed a recent test report of different antifoulings revealed differing results on the SAME antifoul according to area

The main advantage on a mid-speed planing craft is that it doesn't build up too much over the years.

 

[macboatmaster]

exactly that is why it is a self polishing eroding antifoul

Micron Extra 2 is a high strength polishing antifouling

I am not an expert - but I am a licensed commercial and have been at the game a few years

That was exactly the logic why I used Micron2. I have a small boat so one 2.5l tin gives me 3 coats and I didn't see myself keeping the tin from one year to the next. The fact it erodes quicker should in theory ensure that the active part is always exposed and therefore more effective. We shall see if practice confirms this or not, but I thought it worth a try
