If you read my project post “Aurora’s Lunch Caddy” you may have picked up on the weeping Black Dye problem I encountered.
Well MarkwithaK responded and directed me to an other product FROGTAPE.
So I checked it out on the net, not only did I find the tape I also saw some chevron tape as well both of which I would be interested to “Test Out”
I found Masters (an Ozzie version of Lowes) stock the product so I hopped off to purchase some.
Well sure enough there it was,
Green multi-surface “FROGTAPE” what a strange colour!
along with some,
Yellow Delicate Surface FROGTAPE, an even stranger colour!, tape as well but no chevron tape (boo hiss)
Any way after reading up on the product I see its designed specifically for latex paint and the green is mediun adhesion and the yellow low adhesion.
I purchased both and frogged it back home.
I set up a test block of ply the same as I used on the caddy.
Keeping in mind the Black dye is mineral based, this was my test setup
a piece of ply
1 x wad/pad
1 x bristle brush
1 x strip of my existing Blue painters tape 3M 2093 (Reported to be for mineral based paint)
1 x strip of my existing Green painters tape Shurtape CP150 ( reported to be suitable for all paints lacquers and varnishes)
I applied the tape and used the pad to apply the dye
The pad test section is the horizontal section
Removed the tape and it was almost perfect! what could have gone wrong?
So I retaped the ply and used the bristle brush, removed the tape and there was the bleeding again.
The brush test section is the two squares.
Here is a close up shot
Flipping the ply over I applied the Green FROGTAPE and repeated the process.
The left section is the pad and the right the brush
Trying to dye timber with a high contrast mineral based dye and expecting a delineated line is pushing the envelope.
From my tests it can be done with a pad but do not expect the same results with a brush.
I will do some more checking for a better painters tape specifically for mineral based paint.
I expect there will be a product somewhere but as for tape suitable for dye I would have say, “Your Dreaming”
Dye the material before fit up.
Enjoy. or have a good laugh !!
