Introduction: Bottle Cap Tree Trunk Table
I just made a lounge set for my new garden, however I was still looking for an original table. My mind eventually set on a tree trump, however the top of the tree trunk is a little bit boring. So, I decided I wanted to add some color using bottle caps. You don't even need tools, but for some parts they are handy.
- Bottle caps, a lot of different ones, or whatever you want. The amount depends heavily on the surface you want to cover. Getting all the caps is the most fun part ;)
- A tree trunk
- Black grout
- All purpose glue
- Optional wheels, if you chose a very heavy tree trunk.
Step 1: Preparing the Tree Trunks
Preparing the tree trunk is easy, just take some sandpaper (or a sanding machine) to make the top flat en clean of dust and rubbish. Before gluing the the bottle caps the surfaces needs to be clean and dry.
I filled the clearly obvious hole with a piece of aluminium foil.
Step 2: Gluing the Bottle Caps
Before I glued down all the bottle caps I did a test fit. They all fit! Hereafter I used cheap all purpose glue, to glue the bottle caps to the tree trunk. Make sure you drench the edges of the bottle caps in glue, because there is a very small contact area between the bottle cap and the wood.
First you will be thinking it will not stick. I was also skeptical, however after a day it stuck good enough to proceed to the next step.
Step 3: Grouting of the Top Surface
This is maybe the most difficult step if you have never done it. I used dark grout to let the caps visually pop. Prepare the grout as instructed on the package. You need a cottage cheese consistency.
You apply the "cottage cheese" generous over the complete surface with your hands or a sponge. At first it looks likes you will never get a clean surface. After it dries a bit (1 hour, but really depends on the weather conditions), you can use a dry cloth to remove the grout over the bottle caps.
My grout did need some cleaning up when it was not yet completely dry. I did that using a wet cloth to create a smooth surface between the bottle caps.
After it dried even more, almost completely, I used a wet cloth to clean the top of the bottle caps completely. Now they should pop clearly.
Step 4: Epoxy the Top
Start with waiting until the grout is completely dry. Hereafter you can clean the top with a degreaser such as thinner. However, watch out! You can not use all degreasers, because some degreasers interact with the epoxy. Check the epoxy if the degreaser that does not react with your epoxy.
We chose a standard epoxy (mr. boat epoxy) which needed a separate UV-blocker to prevent yellowing of the epoxy in the sun. Two layers of epoxy are applied using a brush. However, this does not result in a perfect flat top surface. I don't think it is necessary and I like the look of the bottle cap dents. (It's a feature, not a bug!). For applying a epoxy pour you need a border, which is very difficult to construct on the highly irregular bask of the tree trunk.
This was my Instructable and I hope you have enough information to create a proper bottle cap tree trunk! If further questions arise, don't hesitate to contact me!
