Karl Posted July 30, 2019 Report Share Posted July 30, 2019 Hi all, well our boat is coming together after several repairs since purchase. The roof however is in need of a re paint and is covered with a textured paint which has blistered and split in parts letting water get underneath some of the paint. The plan is to remove the paint in these areas and rub it down before repainting. Someone said to use Weathertex paint as used on houses but don’t know if this is the best idea. It would no doubt be cheaper than using canal boat paints. Is this a good idea ? Anyone else used this stuff or anything similar from the diy store ? Do I have to clean the roof with anything before repainting ? Your help please ! Link to comment Share on other sites More sharing options...
Tony Brooks Posted July 30, 2019 Report Share Posted July 30, 2019 (edited) I suspect Weathertex is a latex based wall paint and I would suggest that it is not suitable for a narrowboat roof but may be wrong. After problems with pigment shedding after a very few years from a variety of semi-mat paints, including Raddle from Craftmaster, I chatted to a chap at out local Crown decorators centre about a suitable semi-mat paint oil based paint suitable for steel and outside. He supplied a specialist Sandtex paint but it had no sand in it and it is as good, if not better re the shredding than the rest so maybe "someone" got a bit mixed up. This did NOT come from a DIY place. If you have not thought of it a gloss paint on the roof, especially in a light colour to reflect heat, can be a menace with s low sun. It reflects sun into the steerer’s eyes. Edited July 30, 2019 by Tony Brooks Got name of paint wrong, now correct. Link to comment Share on other sites More sharing options...
jeff thompson Posted August 2, 2019 Report Share Posted August 2, 2019 What about "Rhino lining " ? It's a product used to line pick up truck beds. Link to comment Share on other sites More sharing options...

Karl Posted August 2, 2019 Author Report Share Posted August 2, 2019 don't think that would work somehow but thanks for the idea ! Link to comment Share on other sites More sharing options...

You may be thinking of Rhino board which is a Phenolic coated plywood (used for deck-boards and other things) https://www.onlineplaygrounds.co.uk/rhino-board-sp130.html Rhino Lining Rhino Lining costs typically about $500 per truck bed (6 foot x 4 foot ?), so it would be many £1000's to do 60 foot x 6 foot a boat top, Edited August 2, 2019 by Alan de Enfield 1 Link to comment Share on other sites More sharing options...

Johny London Posted August 2, 2019 Report Share Posted August 2, 2019 If you are going to remove paint from just the bad areas, it's likely you'll end up with a pretty patchy finish - dunno if that's of importance or not. There are plenty of semi gloss/sheen paints (do they call it a radle???) around, one of those in a light colour and you can decide whether you want to put sand down or perhaps use strips of that grippy tape if/where you might be walking (which could also help cover up any variations in the surface).

Well, yes. The product, and products like it have very good bonding properties, have a "dimpled" surface, that would be beneficial as an anti slip surface, and I have seen them in different colors. And with the bonding , it would seal out moisture ,eliminating subsurface rust . Just saying.. Link to comment Share on other sites More sharing options...

Extrapolating the cost of having a truck bed 'done' , to having a 70 foot Narrowboat 'done' it would cost around $10,000 You can have a boat stripped back to bare metal and fully painted for less than that.

jeff thompson Posted August 2, 2019 Report Share Posted August 2, 2019 Again, I have never been on a narrow boat, I dont know what the drawback would be. My experience with boat are mostly sailboats, some wood ( sailfish) mostly Fiberglass ( Morgans, Cals, and Hinkleys) which won't be the same.

One of the big (potential) problems would be that having bonded the 'Rhino' to the roof (and gone around / cut out all of the features on the roof (Chimney, Flue, Ventilators, 'sky-lights' etc) is the difference in thermal expansion over such a large are of steel. As an example early Narrowboats had steel hulls and GRP 'tops'. The thermal expansion differences mean that rarely can a watertight seal be maintained, even using 'flexible sealer' to fill in the gaps. Link to comment Share on other sites More sharing options...
jeff thompson Posted August 2, 2019 Report Share Posted August 2, 2019 There are other brands also. You scuff up the paint, apply with rollers, brushes, after taping . Applying two coats. It cost around $80.00 a gallon. If a gallon can do a truck bed, Im thinking ten cans should work, so thats under a $1000.00. Plus you're labor. It might be a good test on a piece of discarded steel. Thanks for allowing me to participate . Link to comment Share on other sites More sharing options...

I have sprayed something similar in the past it came from Rotherham refinishing, it came in various colours in 1 litre cartridges did my Dodge ram with it, dont remember it being expensive and it was tough and I mean tough Link to comment Share on other sites More sharing options...
Clodi Posted August 2, 2019 Report Share Posted August 2, 2019 I've use Hycote & similar on pick-up beds, Landrovers, Travel-Trucks even on wet-room floors inside Surf vans. It's really good stuff. Link to comment Share on other sites More sharing options...
