Quick and reliable
If you work with acrylic you should be working with Weld on. Fantastic product, holds in minutes and fully cures in a day. Seals complement and making acrylic seals waterproof. Just make sure to work ventilated because had a strong smell.

My go to cement for acrylic.
Received in good condition. I've used this product many times in the past, and it works well. It does tend to dry out even when tightly closed. I slow it down by putting the closed container in a tightly closed glass jar. It doe buy some time.

Works very well on acrylic
This solvent works very well when building with acrylic. Complete bond does not take affect for a few days. The acrylic breaks before the bond/weld. I built a 57g AIO frag tank without issue.

Acrylic display case fixed perfectly
This display came broken In pieces when delivered. With the top completely broken along with the pieces in picture complete broken off the case as well. The cement glue is runny but if the broken subject pieces that are fairly snug the glue seeps into the crack easily & bonds the two pieces together, glue dries clear. I used harbor freight clamps along with glue precision applicator bottles with extra long 1.5 inch stainless needle tip 21Ga to ensure that pieces went back together seamlessly.

Worked for the job.
Works well. Wish it actually dried clear. It dries frosty looking on clear acrylic. Wish it came with a syringe for application.
