I’m usng the same laser and getting excellent results. Here is my method For best results with a brush on method measure out 100 ml of PVA glue and I now add 3 tablespoons of water plus two drops of liquid hand soap. Mix thoroughly. Now add one full tablespoon of titanium dioxide to a flour sift. Slowly mix sifted powered to your PVA as you stir. Make sure you mix well. I now strain this mixture through the flour sift into another vessel. Paint on clean tile as you would paint anything with gloss paint. I dry with hairdryer and laser at 1000 mm/m 80% power. 40 watt diode laser.
Hope that helps.
Substitute hand soap if necessary for washing up liquid.
