What Can I Do To Minimize Bubbles?
When working with resin, bubbles are a fact of life, and probably the biggest variable, but there are many ways to avoid/reduce/eliminate them. Your Little Windows how-to guide, and our How-To Videos have tips and tricks at every step. Beyond printing on Little Windows papers, which are waterproof, here are the basics:
If your bottles have been moved around or shaken,
LET THEM SIT STILL
for about 30 minutes to settle.
If your Little Windows Part A (Resin) has gotten cold, it may have thickened up. The thicker your resin, the harder it will be for bubbles to rise, so you'll want to
WARM IT UP.
You can measure out your batch into the mixing cup, then pop the cup in a microwave for 5-7 seconds, until the outside of the cup is just warm to the touch. DO NOT TRY THIS WITH ANY OTHER RESINS OR CHEMICALS, AS THEY MAY GIVE OFF DANGEROUS FUMES. Another option would be to tighten the lid on your Part A, put it in a zip-top bag, and soak it in hot water for 15-20 minutes. Allow it to cool down to about room temp before mixing in your Part B. Do not heat Part B, do not heat after you've combined A and B.
Try to avoid adding bubbles while you stir.
STIR SLOWLY AND GENTLY
, and be sure to scrape the side and bottom of the mixing cup. Stir for the recommended amount of time.
LET YOUR MIX REST
for 5-6 minutes before you pour, to allow blending to complete, and let bubbles to rise and pop. If there are any bubbles clinging to the top or sides of your mixing cup,
scoop them out
before you pour.
POUR RESIN SLOWLY
into your mold, and slide in your photos into the resin, face-up. Wait a few seconds to let the photo settle down into the resin, then use your mixing wand to slowly push the photo to the bottom. Cover up your mold and wait the recommended amount of time so the bubbles have a chance to rise up and pop on their own.
6) After 10 minutes
, if you see any stubborn bubbles clinging to your photos, use your mixing wand to gently scooch them off and up into the mixture toward an edge, so they have a chance to rise up and pop on their own. Give them a few minutes then
scoop any remaining bubbles up and out of your mold.
Another way to avoid bubbling is to
pour in thinner layers
, which also allows you to collage and create 3-D effects!
Watch out for
in your printer, they may cause tiny bubbles to form and cling to the surface of the photo.
