Window Frosting (Application)

Hi there. Hope someone can help. New so bear with me. I'm applying a large sheet of window frosting to a sheet of clear perspex (plastic) In a customer's reception area. Customer/staff will be there so I don't want to look like
a complete idiot. Any good you tube clips would be handy. All the ones I have found seem to be more for the amateur. I know about the spray on water (with a couple of drops of detergent). Is there a more precise measurement to use?
eg 2mills per one litre (or something like that). Does this still apply to perspex or just glass?. I have not found any premix/ready made solutions here. (New Zealand). Not really time to get in from overseas. I'm a little nervous but if I just pay someone else to do it I won't learn myself. (+I won't make any $$$). Not practical to transport it back to my workshop.(to large). Advice appreciated. Thanks Simon

Agreed. What brand/series of vinyl do you have?
To double down on solventinkjet's comment, you will have to throw the piece away if it does have air egress channels and you spray it with application fluid.
 
Thanks guys. It's "ORACAL 8510 - Etched Glass Vinyl" 94 Silver (Coarse). Good to know if I should use spay water with this? ta Simon

I've never used it, but it does not appear to have air egress. Is this solid, or does it have cut graphics in it?
When I use 3m dusted crystal, even on just a fully covered window, I'll premask it first. The stuff is so thin that I'd rather not risk kinking it when it's coming off the backing. Once it's stuck, I saturate a small area with fluid and kindly rub it until the mask rubs away. From there, depending on how well it's adhered to the glass, I'll either leave the rest of the mask dry and tear it as I remove it from that center hole. Some times it releases better all dry, sometimes all wet, I've never tracked down the different factors. In any case, ripping the mask from the center save a lot of headaches with the film coming off the glass again and having to reapply it.
 
Thanks for getting back so quickly. It has a small cut graphic in the middle. The vibe I'm getting is I just need to give it a go. If it all turns to custard I'll just put it down to experience. Almost $200 worth of vinyl so kind of nice if it works out ok.

Right where that graphic is cut out is where I'd dig a fingernail into the mask to start tearing...
I'd say go for it for sure. It helps if you are a funny guy, and tell them it's your first day. This way if it goes up easy as pie, they'll tell you you're talented, and if not, well stuff happens...
That was only kind of a joke. I knew a really young crane operator, like 20 or so, who would tell folks it was his first day and how excited he was to run the crane every time someone said he looked too young to do this. Great operator though.

Check out videos of folks that apply window film for a living. You should be able to find things that parallel you're install.

Since you have a cutout section that will require transfer tape, make sure the application tape is applied perfectly. Any wrinkles or bubbles in the tape can leave a permanent mark on the vinyl. Use plenty of soapy water or application fluid, you want it very wet and slippery. Use a good squeegee, nicked squeegee edges will leave marks, wet the squeegee and the vinyl so it slides easily. Wet the transfer tape to soften it for removal, give the vinyl plenty of time to sit before removing the transfer tape or trimming the edges. I've done large installs where we scheduled the install In the morning and came back later that day to do the final trimming and tape removal. Some etched vinyls are more forgiving than others so there can be a difference for different brands.

I just did an install like this and I should've double checked my squeegee quality. Make sure the felt is new/doesn't have anything caught in it, scratches can be very noticeable :doh:

Also, leave yourself tape tabs on all sides. Finger prints can also ruin an otherwise perfect application of frost. I try to hold on to the tabs to avoid touching the vinyl. Or just give yourself extra material.

Good luck! You'll be fine :)

A. teaspoon of Joy or Dawn dishsoap with 1Quart of water.

B. 1 capfull of Baby Shampoo with 1 quart of water.

I prefer Rapid Tac but since you can't wait these formulas will work. Wet the substrate and film really well and just put application tape where copy is. Use a felt squeegge.

We use 3M Prespacing Tape for masking - not all application tapes adhere well to frosted/etched vinyls -we apply wet using Rapid Tac application fluid, use a squeegee with a felt end, go over it a couple of times, wait a few minutes before removing, spray the masking (wet it lightly) and wait a few seconds for the masking to lift, remove pulling on a 45 (never a 90, as that lifts the vinyl). Just watch your edges, once you get started it removes nicely. Remember when you squeegee to only advance about one third of a squeegee at a time so that you need not worry about trapping some water - lots of overlap and use good pressure. I usually apply one piece, wet the masking, and apply the next and then go back and remove the first. When we used to make our own application fluid, we used water and detergent and added a 1/2 teaspoon of vanilla. Have fun, otherwise, what's the point...
 
Thanks, Does it make any difference that it is Perspex (not glass) ?. any good you tube clips out there?. a link would be fab. thanks Simon

8510 installs very easily, especially wet. It's a thicker material so it's a little easier to handle. As mentioned, apply transfer tape over the cut logo portion, no need to mask the whole sheet (see photos). As soon as you have the whole piece applied, squeegee the logo portion pretty firmly to get as much application fluid out as you can. Then spray the transfer tape with your application fluid and rub it in with your hand. Let it soak while you trim the vinyl, get bubbles out, etc. Spray the transfer tape again, rub it in, start cleaning your tools/area up. Spray it again, rub it in, go to the restroom. Half kidding on the last part, but at that point you should be able to carefully remove the transfer tape from the logo. Peel the transfer tape back against itself, keeping it flat against the glass.

I have always used rapid tac, if i was out or couldnt find any i usually used water and lavender baby shampoo, it is gentler and will not affect the adhesive on the vinyl. make sure you are using a felt squeegy and you srpay not only the back of the vinyl but the surface you are applying it to. you are going to tape it at the top. then gently remove the entire release liner, be careful not to crease the vinyl, you will not get the crease out. then after wetting the rear of the vinyl and the window. you will put a sag in the vinyl letting it naturally cling to the window, you will have less bubbles to contend with. once it is down on the window you need to wet the front of the vinyl so your squeegy moves freely across the front surface of the vinyl and doesnt bunch it up.depending on the size of the vinyl you can squeegy left to right starting at the middle always or go down with it. either way, medium pressure is key, to not onyl get the fluid out but you dont want to "walk" the vinyl out of position.
