Installation and Cleaning (Located in the Restaurant)

What do you need?


  • Tape: 3M VHB Tape 4930F 33mtr. x 12mm, white, 0,6 mm thick
  • Primer: 3M 94 Primer voor VHB Tape
  • VHB cleaner- paper towels
  • gloves
  • brush
  • water level or any other tool that helps you to level the shelves
  • cutter
  • cutting board
  • a pen
  • scotch tape
  • shelves
  • oysters


Step 1: Tape on Oyster shelves


The tape gets rolled onto the shelf to avoid air bubbles in between the shelf and the tape

1) Clean the surface of the shelf with the cleaner (don't be too economical, use a lot) and dry it carefully with a paper towel

2) Don't expose it too long to the outside, get the tape on there as soon as possible. 

This works best when you are two persons. Person A holds the shelf, while Person B rolls it (with the help of the pen) slowly and accurately onto the shelf.

3) Put pressure on it and try to even out possible air bubbles.

4) cut off the tape that is too much 


Step 2: Oyster shelves on window


1) decide for a spot on where to put the shelf

2) clean the spot with a lot of VHB cleaner, dry it again carefully with a paper towel

3) apply the Primer with the help of the brush, very thin. Either on the glass or directly on the tape. 

4) let it dry for 5 min

5) with the help of a level, put the shelf to the spot. Try to apply it slowly from down to up to avoid having air bubbles

6) put your whole body weight against the shelf so it really sticks

7) fix the shelf with scotch tape to the window (fold the ends of the scotch tape, so it's easier to remove it afterward)


The tape needs 72h to fully stick to the window. Only after that weight (oysters) can be put on them!


Important advice

  • the less air, dust, fat is on the tape, shelf or window the better it sticks. So clean thoroughly with the VHB cleaner and avoid touching the surface after it or exposing it too long to the outside
  • the tape sticks best in a warm climate (ca 20 degrees) - Seek for a warm spot to put the tape on the shelves
  • always wear gloves to avoid humidity or grease from your fingers to weaken the tape's strength. Same goes for your face -  donät breath to close.
  • when using the primer, be aware of a good ventilation of the place, don't breathe it in, stay away as far as possible and always close the lit after using it
  • avoid air bubbles in between the tape and the window or shelf and if you see them, try to get rid of them
  • the idea of the pattern of the installation is rather random, so try to have a variation of size and colour
  • Some of the glass is a bit bumpy, gluing on these surfaces is quite problematic (shoutout to windows one and two, look at picture of map). 


How to clean the installation


What do you need?

  • Big brush (in the barn)
  • A small brush (in the red box)
  • A wet cloth
  • 3M VHB TAPE 4910F (the red/transparent one)
  • scissor

Especially during the summer spider webs tend to grow faster around and in between the oyster shelves. Also, small spiders and insects like to live under the oysters. During these times cleaning once a month help to keep the installation in a good presentation.

1) The first step is to use a bigger brush to clean the areas around the shelves.

2) The smaller brush can be used to clean on and under the oysters. If during the cleaning the oyster comes off the shelf you can take it off, clean with the wet cloth and re-install the oyster after is everything dry.

3) The final step is cleaning with a wet cloth and fix the oyster that fell off during the cleaning with the VHB tape. 


How to remove residual tape


When you take a shelve down, it if very likely that there'll be residual tape left on the window. This has be to taken off; to do so you'll need: a small knife, graffiti remover, something to apply the remover and a wet sponge. First remove the big chunks of tape that are stuck to the window. Continue by applying a generous amount of graffiti remover, let it sit for five minutes. Scrape off what you can with the knife and finish removing by scrubbing with the sponge. 

PS: Acetone could possibly work really nicely to do this but this is just a theory, it has not been tested.
