How do you remove air bubbles in the epoxy?
Removing air bubbles is a straightforward process. To do so, you'll need one of the following:
- A propane torch (recommended) - You can acquire these at many home improvement stores, including Lowe's and Home Depot.
- A heat gun - These can be found in many home improvement stores. Although they also work well, they move the air around as they send out heat, which can cause dust particles to fall into the epoxy if you haven't properly cleaned your work space.
Note: Do not use a hair dryer. Hair dryers can't reach the right temperature and are too forceful.
A couple minutes after you finish applying your flood coat, you'll want to begin the bubble bursting process.
When you're at the point where you should start popping bubbles, do the following:
- Keep your active torch or heat gun a few inches away from the surface. Do not let the flame touch the epoxy.
- Move along back and forth across the surface. Never linger for more than a second in any area, or you'll risk causing heat damage to the resin. Keep your movement smooth and consistent.
- Continue doing this until you've crossed over the entire epoxy surface area. This step will usually take around one to two minutes.
- Wait five to ten minutes, then visually examine the surface for any remaining air bubbles and pop them as well.
- Wait 72 hours before using the surface.
Tip: Lowering your point of view to about eye level with the epoxy surface area will make it easier to spot any remaining air bubbles.
Caution: If 20 minutes have passed since you poured your flood coat, do not attempt to use the propane torch or heat gun on the epoxy. It will be too far into the curing stage to handle the heat properly and will be susceptible to heat damage during that period.
