Why does my resin have tiny bubbles?

Porous, organic materials like wood, leaves, fabric and even some soft, lower quality papers contain air and moisture, which they absorb and emit depending on the climate. This is called off-gassing and it results in air bubbles in the resin, sometimes hours after you have poured and torched.

Can you over mix epoxy?

If you mix too vigorously, you can trap air and introduce bubbles. If you’re overly enthusiastic, you’ll get a “foamy” epoxy that looks like whipped cream. Note that a few bubbles will appear in properly mixed epoxy.

Why is my resin still sticky?

Sticky resin is typically caused by inaccurate measuring or under mixing. Sticky, tacky resin: often caused by inaccurate measuring, not mixing thoroughly or by curing in cold temperatures. Try moving your piece to a warmer spot: if it doesn’t dry, re-pour with a fresh coat of resin.

What is the best polish for epoxy resin?

TOPFINISH 2 is a fine finish polishing compound developed specifically for tough plastics like epoxy resin. The super fine nano-particle formulation can be used to achieve even higher levels of gloss on polished epoxy resin surfaces or be used to restore gloss to scratched or well-used surfaces.

How do you make plastic glossy again?

With wet sanding, the clogging is significantly reduced and the abrasive paper can be used for longer.
