Among the various methods to increase adherence the use of lacquer is definitely the most used but how to remove the lacquer from the printing plane? This reinforcement to the membership is used by many makers, and the reasons are moltemplius. Cheapness in the first place, and second reason is certainly the ease with which we can lay it out, coupled with the fact that it is not a dangerous chemical compound. An addition, which not everyone likes, is the unmistakable aroma of a ladies’ wig shop that hovers in the air.
Dulcis infundo the lacquer is much appreciated that for the ease with which you can remove when it is time to wash the heated bed.
How to use hairspray
Not analyzing precisely the situation you might think that the lacquer is used because being sticky glues the plastic to it. After years of use I came up with a slightly different idea. The “glue” component is used to adhere the lacquer to the glass, mirror, metal or whatever. This adhering goes to form a rough bed, on which the plastic goes to stick optimally. As a testament to the fact you can say that you can not start printing with the still liquid hairspray, but you have to wait for it to dry. Once dry it no longer has any adhesive properties, if not really minimal. This is to advise you not to leave a heavy layer of lacquer! The right way is through small sprays about 15 cm away, which let the mixture disperse on the plane. This will form a surface as rough as possible.
For this reason we must not “change” the layer of lacquer until it spoils, and even then you can simply spread out over a new layer. So the washing operation should be done only every tot prints. Only when it starts to annoy the first layer.
Cleaning – remove the lacquer
The method that is normally used to remove the lacquer from the glass top is to place it under the tap and wash the slab with a sponge. This is not difficult or long. The only problem I encountered in this methodology was not having a tap in the printer room. In fact, every time I had to go down 2 floors, wash the glass, wait until it was dry and go up. So I studied another method, just as simple but that did not involve having to do the stairs!
