As a countertop repair person, I usually need a small amount of adhesive, but a huge color selection. It isn’t practical to keep a selection of 250 ml cartridges riding in a hot vehicle, so I’ve been buying Integra Adhesives Surface Bonder Crystal Clear Semi Flowing in the quart size. Integra sells a line of tints, but the pallet is limited, so I purchased a box of acrylic tints at the art supply store.
When you need orange, you need orange, and Integra doesn’t have that tint. Between the Integra tints and the acrylics from the art store, there’s nothing I haven’t been able to match.
This is a classic rear reinforcement rod failure. Pulling the rod has made the crack worse, but that’s not necessarily a bad thing in that it allows more adhesive penetration and the semi flowing is kinda thick. It’s the perfect consistency for repairs because it won’t drip and run away.
I keep a box of Glad Freezer Quart baggies in my kit. I dip a gob of adhesive from the can into the corner of the bag, then apply drops of tint to a stick, shove it into the gob in the bag, and mix until I’m happy with the color. It can be tempting to just drip directly into the bag, but this can be dangerous because you may get more tint than you want. This is especially true with the powerful art store acrylics. It is amazing how even a pin-head size dollop can alter your mix. With the stick-first method, you get exactly what you try. When I’m happy with the color, I drop in the catalyst and mix again. In addition to being much easier to dispense, the baggie keeps the adhesive from skimming over from too much air time like the pallet method, and if you drop a baggie on the floor, the mess is much easier to clean. Don’t dip a color-contaminated stick back into the can either, please.
In the second picture, I’ve mixed a neutral base color, worked it into the crack, then taken smaller baggies of gray and brown and kissed the neutral intermittently. With one swipe only, you don’t want to over-blend, push the colors into each other leaving enough on the surface to allow for shrinkage. The varying colors look like natural veining in the stone.
Surface Bonder is for indoor use only, but I broke the rule the other day. I repaired an exterior bar with epoxy, and as I was adhering my second piece onto the first, the first fell off! I could not believe my eyes. Even though it felt stiff to the touch, perhaps the epoxy wasn’t fully cured. It peeled cleanly off each side of the stone. If I had to glue one day and polish the next, my rates would skyrocket; the repair business doesn’t allow such luxuries cost effectively. I did it over with Surface Bonder, it kicked within minutes, and didn’t budge when I bore down on the unsupported cantilever to polish the top. Fortunately, the bar has a roof over it and won’t be getting much, if any, sunlight, and there is no freeze-thaw cycle in Florida:
I use Surface Bonder on Corian and other solid surfaces with excellent results. I rarely need blue, but sometimes I do:
The deck has seams on all three sides of the sink, and the inside sink edges were built up too.
I won’t use Surface Bonder on larger jobs of solid color solid surface; the color match in that application must be too perfect. Fortunately, Integra’s got you covered there too, just look up your brand’s color on their chart:
The Integra sets up very quickly and polishes to gloss beautifully, both money making attributes in my business. This is as close to stone-in-a-can that I’ve ever found. The people at Integra are always helpful and knowledgeable. Give them a call, please.
