The easiest way to glue acrylic is to use reactive acrylic cement. Acrylic cement is thinner in consistency than silicone and is suitable for small or large projects. Follow these steps to easily glue acrylic yourself.
Step 1 - Decide Which Acrylic Glue to Use
WELD-ON 40 High Strength Acrylic Cement is an industrial strength two-part acrylic glue. It is strong enough to bind edges on aquariums, cabinets, and shelving. There are also many other brands of acrylic cement available.
Step 2 - Prepare the Acrylic for Gluing
Surfaces to be glued must be clean and free of particles. Use a soft cloth and detergent to buff off any dirt or oil. Remove the old glue or silicone from around the area to be repaired. A solvent or blade may be required. Light strokes with a blade are recommended in order to avoid scratching the surface of the acrylic.
Step 3 - Glue the Acrylic
Mix the two components of the acrylic cement together according to the instructions on the package. The solution should be quite runny. Because tack drying time is around eight minutes, ensure you work quickly. If edges need to be glued, tape the underside together with masking tape and use a box or a few books to prop up the pieces of acrylic. Drying time can be anywhere from four to 24 hours.
