Primocon and Epoxy filler

[Archie1979]

Hey everyone,
Well a solid morning in the shed sanding, sanding, sanding and undercoating.
I have just applied the first layer of Primocon onto my hull and have now noticed during the process that my fairing had a little to be desired so there are a few little areas that are low.

My question is can I just use some epoxy filler to fill these small areas or will I have to re-sand back down to the glass and then go again.

As the Hull is wooden when I sand it back to glass its quite hard to see the low spots.

So heres to hoping that I can just fill over the primocon with epoxy lightweight filler then recoat in undercoat.

Thanks in advance everyone.

It depends on how deep the lows are. How are you "blocking" her down to find them? It's very helpful to angle the available light, so you get long shadows on the surface. Generally, this mean low angle lighting and not a lot of it, as too much will hide the low spots in the surface glare.

Gees Paul,
What a fast reply. The lows are only very slight and would not require much filling at all. I have been using the method as you described to find them.

as far a blocking the hull I have been using a long torture board made from offcuts, seems to be working okay so far.

I was probably just a little keen to get underway again.

thanks for the help

I always make sure every layer is a different color so when I sand I know how it is going. Also when it is last layers I paint with epoxy paint and then sand thru it. Anything low shows up big time.

Archie, if you are using a blocking primer, lay down 3 or 4 good coats over the lows, then see if you can long board them flat. Primer really can't fill much more then scratches, but several quick coats of primer is easier then the alternative.

......you have to re-sand back down to the glass and then go again


...do you know about dust coats, where you put a very fine mist of say black over the hull so that you can see what you are sanding, the hollows stand out very well when they are a different colour, and make sure that the torture boads are very flexible to the hull surface, not just ripping out the centre section of the boards, your arms will tell you when the board is working well (poor bugger).....

Key coats are effective. Simple contrasting colour chalk dust and a flexible batten run over the surface works well for spotting lows and highs. Many times the secret weapon of a pro is the understanding , when fairing, of what area is high and what is low. sand off the highs, fill in the lows. Sounds simple !!!!! but its a challenge once the finshing touches are approaching. Some guys are really instintive when appraoching a job.
As mentioned earlier...high build fast dry primer is a good way to fill minor lows.

Sand, fill, sand, paint, sand, fill, paint, sand, paint, sand, paint, sand, paint, polish.

EEK....Life little pleasures...



Oh piece of advise told to me. Always do every coat like it is your last.

Hey everyone,
I have posted some pictures of where I am at with my boat build for those of you out there who have been watching this slow progress.

I have laid the primocon and yacht primer and I am nearly at the stage when I can start undercoating the hull for some final coats of colour and the clear varnish.

It has been a long long process building this boat, due to the fact that I was injured at work and had 2 discs removed and had a spinal fusion 5 months ago so i reckon I have a little bit of an excuse why this project still hasnt been flipped, BUT its getting close now.

enjoy !!

"had 2 discs removed and had a spinal fusion 5 months ago"...owww. come on mate, that is no excuse .......( do hope that you are OK now, back troubles are very painful and basically stop us, be careful mate.

Keep stroking it Archie, you're getting there . . .

[Archie1979]

Yeah the back problems really did stop me allright, things are slowly looking up though.

Thanks for the comments, cheers Paul

Next few days I hope to get some colour down as well as the anti-foul and start the coats of clear.

I am starting to get very excited again she is looking good.

Don't put the anti foul on until you're ready to splash her. Many of these paints need to be in the water or they lose there effectiveness at killing stuff. There's a "window" they like after painting, before you absolutely should splash them. Check with the anti foul manufacture and see what they recommend.

Hi again everyone,
Glad too see some of the old people still on here. I am going to start laying some varnish today, so this afternoon I will get some pics up to show my progress.

Man this must be the longest hull construction in history haha

take it easy all.
