3M sells a variety of spray adhesives, but typically only the 77 (multipurpose) and 90 (high-strength) formulations are available for sale at the local hardware stores. The 77 has served me well for years and Iâ€™ve never seen the need for any additional grip in a variety of applications. Spraying just one surface is adequate for most situations, but I usually spray both for veneer. Also, it seems to work best if at least one of the surfaces is porous - maybe something to do with outgassing. Overspray is inevitable if you want complete edge-to-edge coverage and laying down protective plastic or paper beneath often takes more time than anything else. Be sure to clean the spray tip after each use or else the spray pattern can be unpredictable - excessive overspray patterns and/or blobs of adhesive on mating surfaces. Acetone seems to work best for cleaning the tip itself and I often squirt a small amount in the plastic dispenser tube as well so that it wonâ€™t clog up - just be sure to shake it out after a couple of seconds. This product is best for medium to large surface areas, particularly flat pieces that need to be accurately positioned - it usually gives you a second chance to adjust the pieces so long as you haven't pressed them together. A wooden rolling pin works great as a improvised brayer. I also appreciate that there is no bleed-through on thinner surfaces, such as medium-weight paper.
I work at an interior design firm. This is the only glue the designers like to use for gluing carpet samples. All other types of glues that we have used don't seem to work for carpets. I can't seem to find this glue at office supply stores. Could go to craft stores but don't like to take time out of my day to do so. Overstock is great and has low shipping costs and arrives quickly.
