So I accidentally scratched my dry erase white board with scissors while opening it. Is there a homemade way to get rid of it. I can see a black scratch on it
Hi, thanks for this video. I have an acrylic sign that has glue residue smear marks that won’t come off. I want to sand it and buff it. Is there any manual buff I can do if I don’t have a machine? Or a very fine sandpaper you would recommend?
Amuses me that people over that side call everything 'sandpaper' when the abrasive is anything but 'sand'. Useful vid though. Not sure if novus is available in UK?
I have used half of the heavy and light scratch remover WITH an orbital polisher. This product is the most ineffective product I’ve ever purchased. ZERO impact!!! I have pictures.
Methylene Chloride, also known as Rez-n-bond. Used this for 37 plus years in the sign business. You can make a thick glue with this by adding scrap acrylic pieces to a gallon and letting it sit for a few weeks
I’ve been flame polishing acrylic in the sign business for 37 yrs. I sanded down to about 600 grit. We used straight acetylene with one or two passes along the edges to produce a transparent glass finish. Sometimes with a rag and Methylene Chloride, (which is the main ingredient for gluing acrylic), you can shine up edges with that.
Hello! I was wanting to know I 3d print mostly in ABS, and I sometimes need to put pieces together normally I use ABS glue (mixture of abs filament and acetone) or just straight acetone, would weld-on 3 be a better option than the two I already use when joining piece together or does it depend on how it will be handled/used?
You used to be able to get methylene chloride at any hardware store. Stupid EPA banned it because over the course of 40 years a dozen people didn't follow the directions about ventilation and died. About half of those were stripping paint from bathtubs, a use that the label told you not to do.
Thanks for the info! I am trying to use this technique but I am not seeing an instant bond, it is not "sticking" until it's sat there for a while. Any advice on why? they are laser cut pieces, so all I can think of is maybe i need to lightly sand the edges.
Hello I don’t know if you are still seeing this but I’m trying this method on my anime acrylic stand that has a scratch in it and it removed the scratch but the sandpaper scratches are gone what should I do?
Does this work on saw cut edges? I caught in the middle of the video on the manufacturer's website that they recommend ips weld on 16 acrylic cement instead if not a purely flat finish which your video seems to show?
yes. this is the only way to do it if you're building your own aquarium. my brother has built a ton of custom aquariums using this method.. there are a few RU-vid videos that show the technique.. once bonded, I think he used a bead of silicone where he had bonded two pieces of acrylic together.. like caulking.
Nice video. I have a hairline crack in a hard to find pool filter fitting that was suggested to try capillary action solvent bonding "repair". Where do you source VC-1 or E-Z Fix #309?
Is the bond improved if you can somehow apply pressure to the joint? I'm guessing since the liquid is so thin that an unsmooth surface can also mean a poor bond?
no. pressure is not going to make it melt faster.. it's not a glue. I wouldn't even consider it a bond. the two pieces of plastic are being melted together by the solvent. applying pressure might inadvertently prevent the solvent from spreading as far as it could. that would result in only part of the acrylic coming in contact with the solvent. I've built aquariums using this method and the trick is to ensure both pieces of acrylic are flat, and free of any imperfections from cutting. sanding with a very fine grit is essential to ensure the pieces of plastic lay flat on one another..
worked flawlessly! made holes right on edge of acrylic effortlessly. I used some water with coarse side of Gordon combination sharpening stone from harbor freight to flatten the cutting edge. Took 1-2min to flatten each edge (my bit had 2 edges, was the standard titanium 118 degree bits from harbor freight). You just make the cutting edge of the tip flat instead of sharp. He said parallel to shank, which is incorrect. parallel to the cutting edge. Flatten the sharp cutting side of the tip that makes the angle of the drill bit, opposite the flute. Cheers!
