Lexan polycarbonate glue
Plexiglas is a popular alternative to glass. It is stronger and more flexible than glass and is used for many applications. There are many ways to adhere Plexiglas to different materials. Plexiglas can easily be drilled through and can also be sealed to objects with silicone. Fastening Plexiglas to an aluminum frame will only take a few minutes when done right and any homeowner can handle the job with a few simple instructions.
Clean the Plexiglas so there is no dirt or dust that will get in the way during installation. Wipe it down thoroughly with a clean rag until everything is dry.
Inspect the aluminum frame to determine where the Plexiglas will be attached. Measure the with of the frame with a tape measure and mark on the Plexiglas where it will be installed.
Squirt on the lexan polycarbonate glue inside the area on the Plexiglas where the mark it located. Spread out the glue with a brush so it covers the entire area inside the mark. Repeat the process for the other side of the Plexiglas and spread it so it is level on the surface.
Line up the Plexiglas to the metal frame and push down on the frame so the glue can adhere to the aluminum. Move your hands over the entire area up and down for a few minutes until it is firmly in place.
Look over the Plexiglas and aluminum frame to make sure no glue came through when you were pushing down and wipe it up with a rag if necessary. Clean off the edges of the glass to make sure there is no glue seeping through.
