Placement: We suggest YOU first layout your “pattern” on the floor to make sure it is the look you want, you have enough materials, and everything matches up as expected.
- Color variation: when you lay out your Next acoustical foam, you may notice a slight color or tone variation between two adjacent panels. This is likely due to the direction the panel was cut, and not due to an actual difference in color. To get the best match, once you have laid out the pieces, IF possible, rotate adjacent pieces that seem to be a different shade to the extent it’s possible, until you get the best match. You may still have some slight differences; work with your layout to get the best possible appearance.
- Size variation: because the Next acoustical foam is a “flexible” product, some slight variation in dimensions should be expected due to the cutting process. You may find that one side of a piece is slightly shorter or longer than the side of an adjacent piece. Once again, for the best appearance (if lining up the seams) rotate the pieces (to the extent you are able) to match up the similar dimensions. ALSO, when you go to install the separate pieces, you can make the seams line up a little better when mounting the pieces by ”scrunching” them into one another, insuring a tighter, better fit and look.
Mounting Suggestions: Decide if you are putting the foam absorbers up temporarily (plan to take panels down some day) OR permanent (it is there to stay!).
- Temporary: Many inventive ways are available that include impaling the panels on finish nails on the wall, or pinning it to the wall with fabric t-pins or finish nails, preferably at places within the foam cut that are least noticeable, such as the base on CityBlox™ where it changes to a higher level (BevelBlox™…can do it from the sides angled in.); to better hide T-pins or nails…”paint” ends with black Sharpie. Our experience is that “temporary” adhesives are just that…temporary…the foam falls down. But other ideas include securing the panels to a substrate (such as pegboard or sign board) and then hanging the substrate with picture hangers, or screwing through it to the wall at joints between individual foam pieces (hides the screws).
- ApeTape - Our two-sided tape/adhesive: This high strength, permanent two-sided tape will work well when you can get a good bond to the foam panel; you really need to “smash”/compress the foam to the tape with pressure to create the imbedded bond. Removable, or temporary two-sided tape or foam mounting squares will not work for any extended period of time.
- Spray or Liquid Adhesive: Use the proper products. We sell FoamFast Spray Adhesvie from 3M because we KNOW it works. We've used it successfully for years. It's sold (more expensively) under other names in the industry, but this is the best product we've found! If you're looking for an adhesvie at your local store, many of them, such as some formulations of Liquid Nails™ specifically state to NOT use them with polyurethane foam. Look for the products that specifically state that you CAN use them for polyurethane products. If shopping locally, look for PL300™ (tubes) or certain formulations of Liquid Nails™. For Spray adhesive, same rules apply; look for 3M Super77™ or High strength Super90.™ NOTE: when using spray adhesive, you are better with a general coverage on the foam vs. a concentrated “liquid” puddle(s). If you can spray it such that it comes out of the can and attaches much like spider webs, this is best…it has already started to dry and getting tacky, and actually takes less spray!
TACKING: Highly recommended for liquid or spray adhesive. Put the adhesive on the panel, let it dry a bit (1 to 2 minutes) until it is tacky, then place on the wall or substrate where you want it. Press it firmly (heals of hand, compress the foam). THEN, peel it off immediately (unless it already has a great bond), wait a few seconds, and re-mount it; sounds silly, but really helps. YOU can also put some of the adhesive directly on the wall before tacking for a very permanent install or if you are really fighting it!
Surface Preparation: It needs to be clean and free of dust. Unpainted drywall does NOT work well! If mounting on the ceiling with adhesive, you may want to consider first mounting the foam to a substrate (pegboard, Corex sign board) and screwing the substrate to the ceiling (at joints between foam pieces).
Layout, Appearance and Performance: How it looks is up to you…get creative. Come up with a look that does the job and “inspires” great recordings! If you are treating an area and do not have enough material to cover the entire surface (or don’t want to), then try to treat the most offensive flat surface with 60 to 100% coverage, and treat the other flat surfaces or surrounding area with 30 to 60% coverage. You do NOT have to have 100% coverage to have very effective acoustics. As a general rule, spreading out the coverage and minimizing large flat reflective areas is better than just concentrated areas of treatment.
Good Luck! Thanks for buying products from Next Acoustics!
