Apply and Refinish New Gelcoat over old on a Contessa 32 (ReGelcoating 101)

[@brandonp4255]

I'm a little speechless, Honestly I was waiting for you to drop the ball in process, that not only never happened but you went beyond industry standard, I've worked for several industry leaders and their finishing techniques fall short of your process, seriously impressed.

The tip of using the marker for you guide coat is brilliant. Thanks for that. Very informative video.

[@callummacaskill3247]

I would appreciate a separate video about polishing with the machine as it’s something I always seem to make wrong. Thanks for the good show - I did not skip any second of the sanding part :)

[@whiterabbit3042]

Didn't realize Gel coating was so labor intensive....but it looks great when completed and well protected (that area). Thanks for the lesson...great job!!

[@ELCADAROSA]

Well done! The information and techniques you've presented match that of an American I've been following for a dozen years or so, so you've added to my confidence that I can do this when the time comes. And ... what? No "Oh Glorious Sanding" videos? 😁 That's okay. There's a Danish DIYer who provides me with enough of those.

[@bluethumbdiy4735]

I have to do this to the topside of my boat...and it's long overdue. Great work by the way. I now feel confident on how to take the work on. Just as an FYI, in the states (US) most of us non-professionals use the roll-&-tip method. We roll on the gel coat and then use a very good fine brush to smooth everything out. Because we're out of shape are absolutely obsessed with NOT sanding this much by hand. Some guys who do this dockside for a living, are really good at it. Your final product is better than what we get, so I'm thinking I'll split the baby here and do more sanding, along with the roll and tip.

[@joesmith1142]

i have done both methods, but not very large areas. I agree anything to cut the time down on sanding is a blessing, but i think brushing only gives a much thicker final layer of gelcoat. I suppose if this is true we could just roll on more layers to make up for the difference. I need to do all my topsides as well and am seriously dreading all the sanding. I think for a single person this is a two week project easily.

[@Dulce-Phil]

On my last boat i gel coated the whole deck area. Current boat i painted it with a 2 part poly. Love the durability of gel, but it is tough work and time-consuming.

[@choimdachoim9491]

I'm back for a refresher course from 8 months ago since I brushed my first layer of gelcoat onto my modified helm today. First I was surprised at the depth of the brush-strokes. I was expecting the gel to level out somewhat. Nope. Then I figured I'd have to sand the strokes out but by watching this video again I see that the strokes are typical and to brush succeeding coats in opposing directions. Whew! Glad I checked back with you. I'm using waxed gel so I have to remove the wax between coats.

[@simonroyle2806]

I have watched hours of videos and got more confused on what product to use, this one actually covers exactly what I need to do! I have an ancient Invicta 26 and the top side is horrible, I can see daylight in parts from the inside. So I tested gelcoat on my repaired Laser dagger board and that was a disaster, I didnt realise the gelcoat remains tacky (I didnt know its meant as a mould product where there is no oxygen) so then tried PVA to dry it. Anyway made a mess of it with runs and dead flies, grit, etc. Ended up sanding virtually everything off, gave up and just painted it! So this gives me confidence to have a go on the boat with Gelcoat so I get some depth in the material that I wouldn't with paint.

[@RefitandSail]

Pleased it was helpful, best of luck with the project.

[@simonroyle2806]

@@RefitandSail Reading below I realise I used the wrong PVA (mine was from Wickes so is wood glue), it certainly allowed the gelcoat to dry but what a mess! Sanding it off clogged up the sanding belt in no time and I ended up removing virtually everything I had applied.

There’s a trick that the Chinese painters use for pretreating the brush. Squeeze adhesive into the base of the hairs inside the metal clamp. Let dry and the hairs will not get pulled out. So you don’t need to pay for expensive brush . I have a project Pearson needing a gel coat overcoat. I am thinking of smoothing out to remove brushmark, with sponge paintbrush (paintsponge?)

I am completing a gel coat job on my 23' RIB, radar bar. I'm continuously watching video's to evaluate the process I used to get to the point of block sanding and polishing. The only difference in my application is I used a mini roller, instead of a brush. Thanx for the education..

[@callummacaskill3247]

I’m not sure of your views or experience with rolling 2K paint on topsides, decks and cabin sides, but it’s becoming a popular option for both budget refits and the fact some yards don’t allow spray painting these days. I’d be very keen to see you demonstrate the technique in an upcoming video, cheers.

[@RefitandSail]

Yes you can get some really excellent results with some of the recently produced paints and if you get enough on it can be polished back to an excellent finish. I have a couple of hull repaints coming up but they will probably be sprayed.

[@demacherius1]

That was a verry informative video. Thank you for providing your know how. Now I have some sanding to do.

The concave surfaces can use sandpaper wrapped over a paint roller. A totally ignored tip I have given before on KZbin. But the Beauty of blocking can also be done in the concave.

[@haraldhannelius]

Yes, watching the sanding. At 32:!7 quite some flex in that deck.

[@RefitandSail]

I think the Timelapse makes the deck look like it’s flexing more that it is somehow. It’s solid laminate (not cored) + stringers so there is some flex but not excessive.

[@drjasper100]

Very helpful. I’m about to do some gel coat repairs on my boat. So this was helpful to me. You used gel coat, which surprised me. From what I have ‘read’, I would have thought ‘flowcoat’ is for use like you used it.

[@RefitandSail]

Flow coat is just gelcoat with wax in it that rises to the surface when curing so you don’t have a sticky finish.

[@sailingcacique6343]

Fantastic finish, I didn't see any water for the wet sanding. Thanks for showing us.

[@RefitandSail]

Water was in the bucket, only need enough to lubricate the abrasive.

[@nanosails9925]

I AM watching the sanding because i wanted to know how you worked your way around gelcoat and sanding. As it turns out I have been using the almost exact same procedure. Applying the gelcoat by brush, sanding with 120 grit at the very uneven spots by hand and using an orbital sander with 320 grit on the plane surfaces - but i only gave it four coats and I haven´t sanded through yet. Next time I think that five coats is safer. Thank you for posting this at the right time 😂

[@RefitandSail]

4 should be plenty of applied thickly but 5 gives a bit of margin for error in the sanding so no harm. I tired to do it with 3 coats once and it’s just not enough, 4 minimum, 5 ideal.

[@calvynvandenberg6943]

Suggest you wear knee protection in future! I speak from experience😉 I went for the paint option on my R36, but everything, only the toerail was left on. The deck and coachroof were in v poor shape.

[@walther6799]

A comment if I may, at 22:55 you are showing the sander attached to the hover, however if you look at the sole of the sander, it is perforated in order for the hoover to do the job, but that again requires the sanding paper to have matching holes, otherwise the dust is just going to blow all over. When the perforation in the sole of the sander and the sanding paper are matched, the hoover removes almost all of the dust.

[@RefitandSail]

I use sanding mesh rather than traditional sandpaper that needs holes. That may not be obvious in the video (although I do show the sanding media I think). Google Mirka Abranet or Mirka autonet and you will understand (other manufacturers make similar). Haven’t used traditional “sandpaper” with or without holes for years. Thanks for the comment 😁

[@walther6799]

Ok thank you, that makes sense@@RefitandSail

[@choimdachoim9491]

It's hard to accept you as a pro when I see you crawl around with your bare knees on a non-skid surface without knee-pads. It's not the skin of your knees that gets damaged so much as it is damage to the knee-joint itself. Your career will be shorter without pads. Taking the gel-coat above and below the outside and inside corners results in a much better look for the boat. Nice change. That second coat was cute...paint porn, complete with appropriate music. This video is informative and so are your responses to many of the comments. I appreciate it. I know...that don't buy beer.

[@RefitandSail]

No worries about the beer-tokens, that’s optional but always appreciated. I do normally use a kneeling pad (as I don’t like having pads attached to my knees. Fortunately the non-slip on this deck is very worn and due to be replaced (likely in a future video). Thanks for the comment.

[@darius_83]

Forget the knee pads, but sanding those poisons without a face mask is so smart. That will retire him earlier. I could understand if you do this once a year in your own boat, but if you do this for a living, that I can't comprehend.

Apply a thin CA glue to the base of the brush and let it cure. Then you won't get any hairs in the new gel coat. Model airplane folks use this trick all the time.

Some say he's still looking for that elusive black sharpie. Fun fact, green is actually harder for the human eye to see. In graphics "RGB" (Red/Green/Blue primary colours) is generally set as "565" so the green level is higher to compensate for natural human eyes vs graphics on a screen.

[@gbr562]

How bizarre, as a boat builder of too many years to mention, your method and system is Exactly the same as mine. (even the gelcoat supplier!) I guess the only way I differ is that I use a 3" spreader to apply the top coat, which tends to give me a flatter finished surface. So when I start the sanding process I can use 240g. Then 1000, 1500 and then 3m compund. Good job.

[@RefitandSail]

Well that’s good to hear. Thanks

You don’t want my knees, but a kneeling pad from the garden centre makes it all a lot more comfortable!

[@saublesurfer8197]

Liked so I subscribed. Question. I don't know gelcoat but is there a surface hardness that is harder than underneath? Like a shell. Would a roller have been faster and smoother than the brush? I'm polishing the gelcoat on a 35 year old boat in Ont Can. This boat has never seen the UV intensity of the tropics or salt water. I'm starting with 3000 on a 5 inch disc sander with a half inch foam pad to fit curves and it takes the stiffness out of the disc sander pad. I use lots of water to keep the sanded material washed off. I then move up to 5000 then a buff to finish. In a few spots I'll have to grind cracks and fill. You and your apprentice sure did a lot of sanding. Kudos to you and him.

[@gridfreeca]

thanks for the video, I have not worked with a gel coat, After watching a few times I noticed that the gel coat was used to get a smooth finish by removing most of the coats of gel coat, In autobody we want the coatings to remain as level and thick as possible since it is the protective coating and allows for a sand and recoat of just the finish layer. would it not be easier and cheaper to use resin and fiberglass as a paste to create the perfect flat surface, using the guide coats on the fiberglass will allow a lot less sanding of the gel coat while leaving more of the protective layer this also removes the chances of breaking through the gel coat in the less than perfect areas?

[@nroose]

Can you say something about how you prepped the surface before you brushed on the gelcoat?

[@mikefougere]

Have you used (thin) high viscosity cyano acrylate glue on cracked gelcoat prior to the gelcoat process? Ive had good results in light stress to moderate stress crack repairs...it seeps well into the glass fiber voids repairing the area.

Apply all the coats then sand, you need to build up the thickness of the gel so it can then be sanded back and refinished

[@rperry35]

I ve watched this video a few times and it is a great tutorial. It s really improved my finishing work. My 1972 Buchan 37 could use a gelcoat spruce up for sure. I m curious why so many coats, tho. You say that you abraded with 80 grit and from what it looks like thats a rough up and not a sand down. So theres a good base there. Brushing gelcoat makes for a fairly thick coat. It seems to me that 5 coats is going to add a lot material. Can you comment on that, please?

[@RefitandSail]

Pleased you liked the video, could possibly get away with less coats but it increases the chance of sanding though to the original gel which is a total pain as you then have to rebuild the new gel to refinish again. With 5 coats the finished layer is probably only 0.5-0,8mm so not that thick but a lot thicker than paint so minor scratches down the line can be sanded out.

[@rperry35]

Ok....a bit of latitude there. Thanks for quick reply.

[@RefitandSail]

It looks good, wouldn’t say it stands out because I chose to use a slight off-white. It just looks shiny and new. I’d like to do my Westerly but I’m not sure I have the time as she’s a lot bigger than this co32.
