How to apply and get a truly professional finish. *To ensure a perfect installation you'll need: squeegee, spray bottle, washing up liquid, lint free cloth, masking tape, tape measure, paper towel, pencil. 1.Make a mix soapy solution by adding two drops of washing up liquid to the water in the spray bottle. 2.Clean the glass by spraying the window generously with the application solution and clean thoroughly with a lint free cloth. 3.Measure up from ground level upwards to desired level and make a small mark with a pen at either side of the window. Apply masking tape across the glass between the two marks making sure is straight. 4.Mark the application tape every 100mm using a pencil. This will be the middle of your each sticker. 5.Start peeling away the stickers one at the time and spray soapy solution on the sticky side and apply to the glass. Next slide the sticker in position. The centre of the sticker should be in line with the pencil mark made on the masking tape. 6.Using the squeegee or a credit card, press firmly starting at the centre and move outwards, taking care to remove any bubbles and excess soapy solution. Peel off the alignment masking tape and dry with the paper towel. Allow at least 10 hours to fully dry.
