  • Non-toxic, no fume byproduct
  • Available in sheets or rolls

Get to Your Mosaic Grouting Quicker

NO Days Mosaic Adhesive Film’s key advantage is in its ability to quickly cure large surface areas of a mosaic with no mess. Mosaic Artists can now eliminate the tedious task of having to glue each glass piece or tile and then wait hours or sometime days to cure before grouting. Whether you are bonding to either glass, metal, ceramic or plastics, NO Days Mosaic Adhesive Film ensures your mosaic will be built with ease and held together with strength allowing others to enjoy your mosaic masterpieces for years to come.

A Few Easy Mosaic Assembly Steps

Cut the adhesive film to the size of your substrate and preheat to prep with adhesive or simply place your glass or tile pieces on top of the mosaic film and heat. Heat the entire mosaic or small sections and allow to cool to cure. That’s it! Your tiles are now securely bonded to your substrate and ready to grout.

Make Application Easier by Prepping Your Substrate

Cut the adhesive to the size of your substrate (stepping stone, cement board, mdf, or wood) and place it on the clean, dirt-free surface that you will build your mosaic on. Place the release paper that comes in the package shiny side down on top of the adhesive. Press the paper with the iron on a medium setting until the adhesive turns transparent. Wait for the adhesive to cool and remove the liner. You can now build your mosaic without the adhesive sheet slipping, and heat set your mosaic in sections without the adhesive pulling back.

Adds More Strength and Sealing Capabilities

The uniform thickness of No Days Mosaic Adhesive Film creates a strong, long-term bond and seal between your glass/tiles and substrate. When heated, the adhesive film will begin to flow adjusting for any surface flatness conditions and voids that may exist. You can even stack a few sheets of film if you are working with extremely uneven surfaces or porous surfaces.

Re-Working after Curing with NO Days is NO Problem!

A unique characteristic of No Days Mosaic Adhesive Film is that you can easily remove or reposition pieces of your mosaic, unlike other traditional liquid or cement adhesives. Once you heat and cure No Days Mosaic Adhesive, it can be easily re-worked by simply re-heating. No more having to “break your bond” after curing and risk damaging your glass/tiles or substrate you are working with in the process. No Days Mosaic Adhesive Film cannot be accidentally re-activated by indoor or outdoor temperatures due to its elevated phase-change temperature of 160F/71C (point at which it is heated and turns from a solid to a liquid).


There are no special grouts or grouting instructions required when using No Days Mosaic Adhesive Film. The strong bond provided by the mosaic adhesive film prevents glass and tile movement when grouting.

Outdoor Mosaic Application

No Days Mosaic Adhesive Film was designed with outdoor weather conditions in mind. The elevated phase-change temperature (point at which it is heated and changes from a solid to a liquid) is 160F/71C. This temperature is high enough that it cannot be reactivated by outdoor weather conditions.

Trace Your Mosaic Pattern (preserve your original sheet)

Trace your pattern directly onto your glue! If you enjoy following a pattern, you can trace your design onto the clear sheet of adhesive with a felt pen, or directly on your substrate. The clear film form of No Days Mosaic Adhesive will allow you to see you pattern underneath.

Adhesive Clarity

While not crystal clear, due to the mosaic adhesive film’s thin film form, it can be used in applications where a designer is wanting to minimize the visual effects of adhesive when using clear glass or glass substrates. The amount of clarity with No Days Mosaic Adhesive Film is dependent on the designers ability to apply uniform and even heat to activate the adhesive. If No Days Mosaic Film is being used in glass to glass application where there will be no grouting, then the film can be easily cut to match each glass piece so the adhesive film will only be present underneath the cut glass piece and not within the area between the cut glass pieces typically where the grout would be applied.


Question: I’m having trouble with pieces popping off. How do I prevent this?

Answer:  No Days Mosaic Adhesive film is a heat activated adhesive. In order to get a full bond, the tiles need to be heated to 160ºF (70ºC). Once the tiles are heated, you can move them around easily with tweezers or other heat proof tool. BUT, once the adhesive starts to cool and set up, the bond will weaken if you continue to move the tiles. If you still need to re-position the tiles, heat them up so the adhesive flows again, and then let it cool completely to set. Once the adhesive and tiles have cooled down, you can grout immediately! It generally only takes 5-10 minutes for this to happen.

Question: What surfaces and materials can I use with No Days Mosaic Adhesive?

Answer:  No Days Mosaic Adhesive film will stick to anything except silicone. You can use it on a variety of substrates: wood, mdf, cement backer boards, concrete, glass, acrylic, PVC…anything that won’t melt when heated. Folks have successfully used glass, ceramic tiles, metal, wood, oven bake clay, beads, and even plastic in mosaics using No Days as the adhesive.

Question: Help! My pieces blow all over when I try to heat them with a heat gun. How do I prevent this?

Answer:  When you first begin using No Days and a heat gun, you may have to practice your technique a bit. Just like any new process, there is a learning curve. BUT, once you get it down, your process will speed up, and you’ll find what works for you the best. Try these tips:

  • When building your mosaic, build in small sections and heat as you go. This way, a portion of your mosaic will be set and you won’t need to worry about it moving on you. Cut a piece of adhesive film the size of the section you’re going to build. If you have adhesive exposed when you heat (unworked sections), the adhesive will pull back on itself and you’ll need to lay down more adhesive to cover the bare spots.
  • If you’re heating with a heat gun, be sure to hold the heat gun up high (8-12″) away from your tiles. As the heat gun warms up the tiles, gradually move it closer to your mosaic. As you slowly move the heat gun towards your tiles, you may notice them start to shimmy from the air of the heat gun. Stop moving closer until the tiles start to get warmer and melt the adhesive. Once the adhesive starts to liquefy, the tiles will no longer get blown away.

You may want to try pre-heating your mosaic in a toaster oven, oven or kiln. No Days Mosaic Adhesive doesn’t require high (cooking) temperatures to melt. Don’t set your oven over 200ºF (93ºC). No Days Mosaic Adhesive is non-toxic. Place a sheet of the release liner (white paper that comes in the packaging with the adhesive) shiny side up underneath your mosaic to catch any adhesive that might drip over the edges of your mosaic. You can heat set your mosaic in the oven or kiln. You can continue heating with a heat gun when you remove your mosaic if you need to make adjustments, reposition or add tiles. Here are more pointers for using an oven or kiln. (link coming soon).
