2.mask right along the top of the vinyl
not sure what you mean by this… backing tape.. yes cover the vinyl or it will stretch with the heat of your hands over the time it takes to apply.
tape it on.. or mask it… ? NO! well i didnt in demo but its possible if you prefer too…
yes.. Apply at beginning 24inches. After that have someone holding the vinyl taught.
If its is evenly pulled taught the vinyl’s doesn’t really have much option but to go level.
This doesn’t mean you don’t still hold it level with your marks…
Make a series of marks. Maybe every 24 inches. Apply first 24inches and then peal back another apply that and move on. Each time making sure your still level..
Expel the air by up & down motion, as this is the shortest route for air to escape.
Remember when applying dry, you must treat the vinyl pretty rough. Lifting and pulling I mean. If you try to ease this stuff off it will only stretch or cause creases..
If its not going down right… yank it in short sharp tugs! Nothing less!
