Chrom Posted June 1, 2016 Share Posted June 1, 2016 Hello all, I have just invested in a bottle of Glue n' Glaze and wonder if it really works and how strong it is. I have some ground signals with a 1.5 mm hole for the lens aperture, and am hoping to create a lens using Glue n' Glaze. I wonder it it is strong enough to use in this fashion or not, if not I will use it for just refitting plastic windows. Otherwise, any ideas of making round windows that small. I don't have a hole punch that small and I have 30+ to do. Link to post Share on other sites More sharing options...

sharris Posted June 1, 2016 Share Posted June 1, 2016 PVA gives just a good a result! You might be right - I have a bottle of Krystal Klear at home - it does quite closely resemble PVA. Link to post Share on other sites More sharing options...
Guest 40-something Posted June 1, 2016 Share Posted June 1, 2016 You might be right - I have a bottle of Krystal Klear at home - it does quite closely resemble PVA. I only found this out after I'd bought some glue n glaze a number of years back! Link to post Share on other sites More sharing options...
Kelly Posted June 1, 2016 Share Posted June 1, 2016 PVA can have a habit of going yellow and gooey over time I've found in other uses. Link to post Share on other sites More sharing options...
RMweb Gold Dunsignalling Posted June 2, 2016 RMweb Gold Share Posted June 2, 2016 I think all these products are basically high-quality (pure?) PVA. I did some successful windows many years back using a smallish (approximately half a pint) bottle (Platignum brand, I think) sold for children's Art/craft usage which remained clear as long as I had the models. PVA "Builder's" or "Woodworking" Glue, purchased in larger bottles/tubs from DIY sheds is formulated for just those activities, primarily with strength and durability in mind. It can be expected to contain additional ingredients to that end. Any claim that the stuff "dries clear" is based on the needs/expectations of woodworkers but, as a general rule of thumb, the more you pay the clearer it dries. There won't have been any consideration of what else railway modellers might use it for after we've finished making baseboards! John Link to post Share on other sites More sharing options...
28XX Posted June 2, 2016 Share Posted June 2, 2016 Indeed some woodworking PVAs have a proportion of inert filler (talc ?) to give them some gap-filling properties. Link to post Share on other sites More sharing options...
Les Bird Posted June 2, 2016 Share Posted June 2, 2016 As a regular user of Glue'n'Glaze I can confirm that it works well and will fill surprisingly large apertures if applied as per the instructions. I've had some in windows on road vehicles for a long time with no sign of yellowing Link to post Share on other sites More sharing options...

I've had some in windows on road vehicles for a long time with no sign of yellowing It is a special formula so shouldn't yellow. My reference above to yellowing is from experience of using other forms of PVA. I use a thing called Mod Podge a lot in my other crafts, and that also dries nice and shiny clear, but isn't cheap stuff, but is great for applying paper or fabric to card or wood.

stevejjjexcov Posted June 4, 2016 Share Posted June 4, 2016 Hi like Kelly I've used Mod Podge and it does work well but keep it dry and yes some woodworking p.v.a glue does have inert fillers to aid gap filling this is why it yellows over time. You could try Marvin Medium its used to thicken watercolour paint and gives a slight sheen to it but it dry's clear. Any good art shop should sell it or something like it. Another crafters product is Nuvo Crystal Drops but not sure if they do a clear one would be good for lenses as it retains a dome shape Link to post Share on other sites More sharing options...
bertiedog Posted June 4, 2016 Share Posted June 4, 2016 Glue n' glaze is not PVA, but is just called a polymer by the makers. It behaves like PVA till dry, when unlike PVA, it becomes waterproof, like an Acrylic varnish or paint. There are waterproof grades of PVA, but not as good as Glue n' glaze. The dried Glue'n glaze is crystal clear, unlike PVA, which in some grades can dry to clear. Most PVA glue contains fillers to some degree, especially wood glues, and although the glue dries clear, the fillers mean is is milky or white. Mod Podge dries clear as it has no fillers. Glue n' glaze also adheres better than PVA to plastics in general, suggesting it is acrylic based. I use it for the laser cut board kits for the delicate glazing bars, the window is glazed with polystyrene, or PVC, as usual, and then the whole window, with the fine glazing bars is given a coat by rush, of the Glue n' glaze. It glues the glazing bars to the plastic, and dries to give a good clarity, which is a bit less smooth that the Poly glaze plastic, giving a glass like finish. A second or third coat will give a ripple glass finish like old pre-float glass glazing. Bullseye panes can be added by drops of the Glue n' glaze, which dry, but leave a nice distortion effect. In small holes it can be self supporting, it it fairly strong and waterproof. It can also be used for water effects, but would be very costly for rivers! When used in self supporting, once dry further coats can be done, or acrylic varnish can be used to strengthen it. The strong bond with Acrylic again suggests it is the same material base. Stephen.

bertiedog Posted June 4, 2016 Share Posted June 4, 2016 Nuvo Crystal Drops are very much the same as Glue n' glaze, but thicker, and regrettably only made in colours. I have never seen a clear listed. Stephen. Link to post Share on other sites More sharing options...
