The more you leave tape on the wall, the harder it is to remove and the more likely it is that paint will probably come with this. If you’re finding this out the hard way, help can be found. Lubricating the tape generally helps, provided that the lubricant can contact the adhesive. Once the tape is gone, then the outline may still stay. You can get rid of this with a glue made from just two common household ingredients.
The Gunk That Binds
The sticky coating on masking, duct, cellophane and other tapes is a pressure-sensitive adhesive that, unlike other glues and cements, doesn’t need to change from a fluid to a solid in order to bind. Actually, that means that you need to be able to pull it away any surface to which it is adhering. PSAs come in varying strengths, however, as producers find the happy medium between an adhesive that sticks vigorously and one that’s easy to remove. Masking tape is color-coded according to binding strength; green and blue are the easiest to remove. Stickers and decals are intended to be permanent, but tape seldom is.
Soap It Off
If you can’t readily remove masking tape from the wall, then one of the reasons might be that the PSA has lost its versatility, that becomes increasingly likely the more you leave the tape on the wall. Even though you might continue to be able to have some of it away by digging at it with your fingers, you’ll probably should lubricate the rest. Spraying a solution of warm water and dishwashing detergent is generally effective for removing dried masking tape. The water softens the paper financing while the soap loosens the bond between the tape and the paint.
Peel and Unstick
Tape which has a nonporous financing, such as duct or cellophane tape, will soften strong solvents such as acetone or lacquer thinner, but these chemicals are very likely to damage painted surfaces. A safer option is to use a combination of scraping and lubrication to remove them. Beginning at the peak of a stubborn bit of tape, carefully peel back the border with razor blade and spray a lubricant, such as a dish soap alternative, white vinegar or olive oil. Permit the lubricant to penetrate, then scrape a little more and continue in this way until the tape is off.
The Coconut Solution
Most kinds of tape discolor the wall when left for an extended duration, and deposits remains even after you manage to remove them. You can create a glue that eliminates this discoloration and deposits with equal elements of coconut oil and baking soda. Coconut oil softens the adhesive, while baking soda provides only enough abrasive activity to clean it away without damaging the paint on the wall. The glue works best if you leave it on the affected area for many moments before you rub it away with an abrasive pad or fine steel wool.
