Porous/uneven surfaces will require priming, filling or sealing eg. plaster, concrete, wood and fabrics. Metal surfaces need priming or abrading. Low energy surfaces suchas non-stick paints or polypropylene plastics containing aggressive plasticisers need treatment.
Clean surface, for best results use Permastik Isopropyl Surface Cleaner.
Frequently Asked Questions
Is there an ideal application temperature?
For all Permastik Removable Hooks, the ideal application temperature is 10-40°C. For applications below 10°C heat the surface with a hair dryer and apply to surface while the temperature is still above 10°C.
Can I use removable hooks on freshly painted walls?
Paint should be fully cured (check paint can for manufacturer’s cure time) before using any Permastik Product. We recommend waiting at the very least a week before use on fresh paint. Also, isopropyl alcohol used to prepare the surface may remove or dull the surface of fresh paint.
Can I use Removable Hooks on wallpaper?
No. Most wallpapers are too delicate and can tear when adhesives are applied.
What happens if I pull too hard and the strip breaks?
Use dental floss to gently cut through the adhesive substrate and remove the object from the surface. Stretch or peel off the remaining adhesive, use an adhesive solvent to best results.
Why do I have to wait an hour before using the hook?
The one-hour wait ensures that the adhesive has had enough time to build strong adhesion to the wall or surface.
Can I use more than 1 hook to hang an item heavier than the weight limit?
Due to safety concerns, it is not recommended to exceed the weight limits for Permastik Removable Hooks.
Why can’t I use a regular household cleaner to clean & prepare the surface?
Many household and window cleaners leave behind a very thin layer of residue that affects how strongly the adhesive will bond to the surface. Isopropyl Alcohol evaporates without leaving residue.
