TKB B1 trowel for Soudal 26A adhesive

Soudal 26A adhesive for vinyls, carpets, linoleum etc. requires application with a special notched trowel - trowel designation TKB B1 (B1 means size-shape-tooth spacing)
Since I didn't have such a trowel, and buying a metal one (for an inadequate price) for a single job (after which - dirty with glue - it would probably be thrown away anyway) - I designed my own, printed, disposable - but cheaper ;)

Practical tips:
- use a clean new trowel every time. (print some spares) Discard the old one or use it only for applying glue from the bucket, because teeth clogged with old glue in the trowel cause the formation of too low “glue ridges”!
- apply glue from the bucket with a regular (cheap) spatula (or an old notched trowel, already dirty with glue), and with this trowel - only spread it on the material to obtain glue ridges of appropriate height.
- the smaller trowel (132mm) is better than the 200mm wide one, unless you really need to cover large areas

- if you don't know how much glue to apply - apply less, nothing will happen even if there are several-centimeter patches without glue. The carpet will not magically detach in that spot, because it will be held around. If you apply too much glue - it will be much harder to deal with removing the excess…

- corners and edges are most important - apply glue from the edges towards the center, not “I'll get to the edges at the end”
- if a drop of glue drips somewhere, making it dirty - DO NOT WIPE. Once it dries (24h?) you will remove one snot-like blob of glue, it will fall off completely. But if you smudge it - you probably won't clean it to zero anyway, and there will still be marks… And then by removing those marks - you will remove them along with the paint and substrate…
