How to Glue Brass to PVC
Learn how to glue brass to PVC using our easy guide and quick tips. If you are doing some DIY repairs around the house JB Water-Weld is an excellent choice. The epoxy resin is permanent and can be cured underwater or while damp making it ideal for fixing leaks.
PVC and brass are often used in piping and plumbing making it essential to have a quick fix on hand in cases of leaks, cracks, and breaks. Whatever adhesive you use has to bond well with non-porous materials like when gluing brass and be waterproof. Whether you are fixing a leaky water pipe or patching a boat you can use JB Water-Weld or similar products.
Plastic and metal are two very different materials and both can be nonporous which makes it more difficult to connect them using certain adhesives.
What Glue Can You Use for Brass to PVC?
You need to make a list of necessary features to help you choose the right adhesive options. Many types of glue work for plastic or metal but fewer can be used for both. Before you get started make a list of factors that will affect the glue including how long you want it to last, the environment it will be in during curing, and what kind of stressors it might be subjected to on a regular basis.
Epoxy Resin
Epoxy resin is weather resistant and creates a flexible, strong bond between a wide range of materials including metals and plastics. The versatility and permanent nature of the adhesive makes it great for repairs and DIY around the house. If you choose this method make sure whatever epoxy resin you get is designed to work with both metal and plastic.
JB Water-Weld is one of the best epoxy resin products on the market for this type of project. You can use it on large or small repairs, indoors or outdoors. No matter what type of DIY project you have in mind KB Water-Weld makes an ideal adhesive.
Silicone Adhesive
Silicone adhesive needs to fully cure to be effective and depending on the size of your project that might take several days. However, unlike many other adhesives, some silicone dries faster when subjected to humidity or dampness. For smaller boating repairs you can use silicone adhesives as an excellent glue that connects brass and PVC.
How to Prepare Brass and PVC Before Gluing
You need to do a little more to prepare the brass before you apply adhesive to the surface. Metal can be difficult to bond with because it is smooth and non-porous giving the adhesive very little to grab onto. A great way to strengthen the bond is by using sandpaper to lightly sand the brass where you will be gluing it to PVC.
Quick Tip: the surfaces need to be thoroughly cleaned to get the best result. You can wash them with warm water and soap before drying both surfaces and brushing away any debris with a soft brush or cloth. If you sand the brass then this step is essential to remove any tiny metal particles that might be stuck to the surface.
How to Apply Glue for Brass and PVC
You should apply glue in an even layer on both surfaces. Let the glue get slightly tacky before slotting the pieces into place. The glue should reach all the edges for a stronger bond.
How to Cure PVC to Brass Glue
Most glue dries best in dry, warm environments but some brass and PVC projects require waterproof adhesive to work well with piping or water tanks. How long it takes to cure will depend on multiple factors including temperature, humidity, and how thick you apply the glue.
You may want to clamp the materials together for a more secure bond. The faster your adhesive cures the easier it is to keep each piece in position until it fully dries. JB Water-Weld takes only an hour to fully cure and 25 minutes to set giving you time to make sure everything is where you want it.
Conclusion
Epoxy resin adhesives like JB Water-Weld are excellent for creating a strong, permanent bond between brass and PVC. To get the best result and strongest bond you need to clean each surface before applying an even layer of adhesive.
