• Using Rapid Tac 2

    Posted by Robert Scullion on September 15, 2006 at 6:56 am

    Bit of advice, please. Just done a fairly large job (for me anyway) applying oracal 8510 etched glass film, 6 panels, 610 x 2400 reverse cut installed on the inside of the glass.

    Used RT2 for the first time, hoping it would speed up the process, but felt I wasn’t any quicker than using my usual small drop of johnsons baby bath with water.

    Cleaned glass, sprayed glass with RT2, applied film, squeegeed twice, moved onto next glass same again, by the time i got to final window i was hoping to just remove app tape, didn’t happen, had to go back next day and a couple of small fidly pieces still being awkward.

    Am i doing something wrong, is this stuff over rated ?

    Thanks in advance

    Depends on the day if it was a dry sunny day or damp either way can affect the drying I find if you spray the front of the application tape with the rapidtac it softens it enough to make removal easier

    There are two different types of Rapid Tac, regular and RT2.
    Rapid Tac 2 has a faster "kick" while the regular is more "slippery" if you know what I mean.
    RT2 is recommended for use on glass and applying vinyl in colder temps.
    You should email Roger Bailey with direct questions….
    His contact info is probably on their site.

    i did the same job 2 weeks ago using rt2

    it went fine using rt2
    i always spray the application tape just before i remove it

    by the time i had done second section the first was removed

    Thanks for taking the time to reply guys. Maybe its just me, dont know if I used too much but did squeegee really hard to remove as much liquid as poss. Have read the instructions on the bottle, only difference is they say to spray vinyl, I sprayed the glass but shouldn’t think that would make any difference

    Thanks again

    I don’t think you did anything wrong Bob. That’s just the way glass is – completely different to any other surface we have to work on.

    It doesn’t make any difference how hard you squeegee, there will always be a tiny film of moisture left and, until that has dried out, it just ain’t gonna stick.

    Coming back tomorrow is always a good plan, provided you can get the customer to accept that.

    Hi Guys

    I don’t think you need to leave it a whole day, at this time of year as Richard said do second section and then go back to the first – say 45Min’s is long enough but if you have really small detail bits then next day visit may be unavoidable.

    just to add i always use mactac for the etch so may be that makes a difference

    when doing large sections i tape the etch from the top pull all the backing and spray well,i then spray the Glass and any surrounding frames,i think the biggest help is spraying the application tape to help remove

    I spray both the vinyl AND the surface…flood the hell out of it.
    Squeegee out as much as possible.
    Let sit a minute.
    The spray the entire surface (over the transfer tape) and squeegee again.
    This makes the tape very easy to remove.
    Sometimes I use Windex for this step as it is cheaper than Rapid Tac!

    rt is clearly cheaper in the us then ! costs around $8.50 for a tiny bottle here !

    i rarely do etch wet now though

    I have given up using RT2 just can’t get the knack of it, so still use baby shampoo and water. I asked on here before tried all suggestions but just does not reduce app time and I get more bubbles. 🙁 This id for flood coating panels, windows I do dry.

    If applying wet, i think rapidtac is the best method because the liquid has a form of stimulant to help activate the glue on the vinyl. i did a few little tests with a sample bottle i was sent a couple of years back. my workshop was freezing and i was applying some scraps of vinyl to a bit of cold aluminium.
    in short the bit applied using rapidtac had a much better bite than the bit using fresh water. in my view any additives in the water such as fairy liquid etc only extends the drying out time anyway. if i was using rapid tac to apply i would not use it on the rear application paper, to expensive… use fresh water spray on that.

    im not being funny but, if we arrive to apply something in a customers shop window, we cannot expect the customer to have us hanging around for the whole day because we are waiting for the fluid to dry. they have to run their business too after all… if you know upfront this to be the case ide advise fitting just before closing and being there next morning to remove before the customer starts trading again.

    we had a regular on this site a couple of years ago that advised people that it was acceptable to return each day for up to 3 to 4 days just checking the vinyls were still as they should be and if need be, then remove the application tape as the water should now be dried out.
    to me this is rediculaous. i for one would be fuming if i was the customer.

    glass is super smooth and can cause problems at the best of time with moisure trapped behind the vinyl. a tip would be to apply the graphics dry, but late in afternoon when sun has gone down. cold glass is easy to apply onto dry because the vinyl just doesnt take to it right away.
    that said, if applying vinyl to "COLD" glass make sure it has application tape because the cold will make the vinyl go brittle.

    as i always say and ill try not to bore you… apply DRY! 😉
    PRACTICE MAKES PERFECT. 😀

    rob i agree with you on dry application but i have had more than a few probs with dry application on etch so i stick to rt2
    but thanks for tip on just water to remove application tape didnt think of that and another point if you do use lots of the stuff to apply it smells so bad that it stinks the place out
    will use just water on the backing next time
    thanks rich
