Hi ladies and gents.

Just a quick one - if I want to create a pumped PVA spray glue (I avoid aerosols), what mix of PVA and water would a chap use? Also, I presume a couple of drops of washing up liquid would be wise?

TIA,

Bobby

Morning Andy !
The mix needs to be thin enough to pass through the spray unit, so if you try a 50/ 50 mix in a small container and then see if it passes through ok .If it does then add a couple of drops of washing up liquid to a mix and put into the unit .
I've found that a pipette of IPA on the area to be sprayed helps break down the surface tension and the spray mix will flow extremely well .
Have a look at Luke Towan on UTube for list of videos on PVA mixes .

Same here, fifty fifty with a single drop of dish soap to act as a dispersant. However, be sure to rinse the spray nozzle through carefully afterwards. The glue will set in it and block it solid otherwise.

Thank you all. Yes, I figured I'd need to clean nozzle and tube after each use, and seal it up just in case. I'll check out that Glue Guru's videos. Thanks again!
