Extra Strength #90 Spray Glue

Easy of use and very effective.

J’ai connu ce produit il y a plusieurs années….. Ce n’était pas fait pour ça mais, dernière minutes et n’ayant pas autres choses….. J’ai collé toutes mes tuiles-céramiques du plancher et murs avec ça. Convaincu que les gens qui ont pris mon logement après mon départ ont dû avoir des problèmes pour les enlever. Évidemment, pour quelque chose de plus intelligent, ça répond très bien à la demande désirée.

I initially purchased this to keep my 3M Thinsulate stuck to the van walls. It works GREAT!!! I only needed one can. In fact I used the can for other projects too, like gluing lino to bike trays for the van conversion.

So... 3M "ain't what it used to be" BUT, their Hi-strength 90 is still AWESOME. It is easy to apply, has relatively low odor for an aerosol-delivered adhesive, deploys consistently through a very functional and pattern-versatile nozzle, and holds incredibly well. The spray pattern is easy to control with very little overspray/unruly discharge and the application rate is consistent every time you press the sprayer head. I ran a sign shop for years and used this stuff religiously for panel-to-panel bonding (and other creative applications) and it never failed. Recently, I used it to bond thin wood veneer "skins" to the sides of cabinets- some of which were very large and unruly, and all inside a finished home. The "stick" was perfect (make sure you have everything aligned before ANY surface-to-surface contact is made!) and the bond has been rock solid- no bubbles, delamination, curl, or separation. If you follow the manufacturer's instructions, you are golden---- with one caveat: If you are applying to unprimed/unsealed wood or other porous surfaces, you may want to go fairly heavy with your coating and undercut the set time a bit.

Excellent produit.

UPDATE: 3M did come through with a refund, they did not come thru with a solution for the problem I was having, or instructions to help contend with the new sprayer, they were more into appeasement (which is not a bad thing). Anyway I found something new out on my own. I twisted the slot horizontal, which was counter intuitive for the left-to-right-down-right-to-left zig-zag movement pattern I was going to make with my arms. It was just a try on my part, a curiosity. I got a very satisfactory result, and had that been my original experience I would have never authored this observation about the new spray tip. I presume, but haven't tried, that if I turned the slot vertical that spraying up-down-down-up would go better (again counter intuitive). I change the review from 2 to 4,holding back on the 5th star because 3M could have explained better on the can, or packed the can in a retail box with instructions, or created a YouTube example and pointed to that on the can for the sake of brevity. To leave the customers to find out by means of serendipity how to work with the new tip was asking a lot IMHO. Even now it's not too late for them to instruct the public with what they had in mind instead of waiting for the public to guess what design engineers had in mind. My 2 ¢ ORIGINAL REVIEW: The most recent can I received had a new kind of spray tip. Instead of the typical aerosol spray head (a small round orifice) this had a t-shaped protrusion out of the nozzle that had a slot in it, and you could turn this slot to be horizontal or vertical (see pictures). It's a terrible implementation! The old spray head would put out a thin, consistent, and predictable cone of spray. In short you just had to be careful not to spray beyond the bounds of what you were applying it to The amount was very thin, minimalist, but very effective and drying quickly. This new head didn't spray reliably in horizontal or vertical positions and movements of my arm back and forth or nearer/further did not help control it. What came out of the T-nozzle instead of being a thin predictable coating was something that looked more like it was trying to create that silly string spray kids play with. I ended up with voids in areas I would have formerly covered reliably/predictably, and other areas where it was piling on and up three-dimensionally with too much adhesive. 3M sounds like they're going to credit me, and while that fixes my wallet it doesn't fix their product. Between the two fixes I wish they'd fix the product. This new nozzle might clean at the flick of a fingernail, but I managed to keep the other spray head clean, and with that former head I could get the adhesive applied perfectly, now I don't have that, or a solution for it.
