How to choose the right masking tape

Multiple factors should be considered when selecting the most suitable masking tape for a particular application. Making the right choice is therefore not as simple as it would seem. One must take into consideration:

• Surface: what is the tape being applied to
• Agent: what is the tape coming in contact with; paints, primers, lacquers, varnishes, sealants, solvents, chemicals
• Exposure to: UV, moisture, temperature
• Duration: how long tape will be applied for
• Holding power: light-medium-high
• Critical need: clean removal, sharp paint line

This guide is designed to make this process easier.

Tips & tricks for optimal performance

Helpful tips and tricks to guarantee the perfect job.

How to apply masking tape

1. Clean and dry the surface first: Even our stickiest masking tape won’t stick to a dirty or damp surface. Extra time spent prepping the surface prior to application will ensure a better outcome.
2. Applying the tape: Apply adequate downward/firm pressure across the entire width & length of tape (wipe down blade/credit card etc). This will not only guarantee your masking tape sticks to the surface applied to but also ensures edges create a tight seal, otherwise you risk it lifting, paint bleed under the tape & uneven/messy edges.

How to remove masking tape

1. Timing: Never remove from wet paint. Allow sufficient time for the paint to be slightly dried (dry to touch is easiest method) to determine this or check the paint manufacturers instructions.
2. Score the edge of the tape: Very lightly and gently run a razor blade or other sharp object (without cutting surface underneath) along the edges as this will ensure the tape separates cleanly from the cured paint preventing both paint being pulled up and cracking along the paint line (especially if the tape has been left on for an extended period). This also reduces risk of the masking tape ripping during removal process.
3. Removing the tape: Doing it slowly is the key so be patient. Ideally you want to pull the tape up at a minimum 45 ̊ angle to prevent any residue being left behind. If this occurs increase the removal angle to 90 ̊ degrees.

Following these 3 simple steps will ensure you end up with a professional looking job.
