Water based \'varnish\' - polyurethane

Recommended by DIY experts for hard duty on wooden floors etc.

Anyone got any thoughts about using it on a boat.

I use a hardwood garden furniture product on my handrails - just light sand off then splash on a coat or 3. Seems to be lasting OK.

They're usually based on an acrylic resin so pretty hard and durable once cured. You must keep them dry until fully cured though. Any water that gets onto the surface for several days after application can damage the structure and weaken the film permanently. High moisture content in the wood will also inhibit good film formation but that's not much different from an oil based varnish

I used this stuff on the floor;

It is very hard wearing. This was after the water based stuff failed, possibly because it subsequently got damp and the went a sort of white colour. But do note the description it smells very strongly , you could not stay on the boat for the 12 hours after application!

I had been told all sorts of good things about it so I gave it a try on a pice of Queensland Ironbark. The timber dried out a little bit more after the varnish was applied, resulting in tiny haircracks all over the piece. I felt that it was a bit too rigid for my liking.

Anything that ays for ineterior use, may not have sufficient or suitable UV inhibitors for use outside. Just something to be careful of.

Burgess do a woodseal that will give you the colour of teak and protect the wood from UV light.

They also do a Topgloss that is UV stable and will give you the gloss finish of varnish with about three to six coats. The beauty of this is that you can recoat after approximately 30 mins. I have used it on interior and exterior and I find it is as durable as varnish but much easier/faster to apply.

I always use foam brushes when doing varnish work. Last year I used Le Tonkinoise on the exterior, as far as I.m concerned it is no better than Burgess.

The floor of my cabin is done with Burgess products and has been walked on for the last four years by both human and canine, it needs doing again but has stood up well to the traffic.

The beauty of this product is it will take me about 2 hrs to prep and varnish the floor again.

I have no connection with the company other than I use their products.

IN MY OPINION-Water based varnish is rubbish because it raises the grain,is inflexible and gives a weird coloured finish,whereas a high quality polyurethane yacht varnish provides that lustrous warm glow which is why we varnish in the first place mebbe?

I've used it on internal teak floors for several years with good results!. However from experience it doesn't look great on floors that get wet regularly.

Used it on a bathroom floor & no problems!
Still looks good.

Re: Water based \'varnish\' - polyurethane

Well only the first coat will raise the grain, and a light sand will sort out that - and we allways sand between coats don't we? It is pretty inflexible though and it usually leaves the wood almost as light as before it was varnished. Having used it a few times I think it's great for your living room, but I wouldn't use it on my boat.
