SUMMARY

The best methods for attaching PVC in boat construction include using solvent glue specifically designed for PVC plumbing, which provides a strong bond and is cost-effective. A cleaner is recommended to prepare the surfaces before application. For enhanced strength, lap joints are preferred over butt joints. Additionally, marine-grade adhesives and plastic welding techniques can be considered for optimal durability in marine environments.

PREREQUISITES
  • Understanding of PVC plumbing adhesives
  • Knowledge of joint types: lap and butt joints
  • Familiarity with marine-grade adhesives
  • Basic concepts of plastic welding techniques
NEXT STEPS
  • Research the properties and applications of marine-grade adhesives
  • Learn about the techniques for plastic welding PVC
  • Compare bond strength between solvent glue and plastic welding
  • Explore best practices for creating lap joints in PVC
USEFUL FOR

Boat builders, DIY enthusiasts, and anyone involved in marine construction or repair who seeks to ensure strong and reliable PVC connections.

does anyone know the best way in which to attach pvc with pvc? this is for a boat, so it must be as strong as possible.

The glue sold at home centers for attaching the PVC plumbing bonds the plastic together quite well and is fairly inexpensive to boot. There is a cleaner as well (typically sold right next to it) and aside from a nasty smell they set quickly and are easy to use. With the PVC plumbing, it seems the tubing is as likely to break as the joint if you try to separate a joint that did not set in the right direction...
 
You could somehow melt the PVC and let it cool. Haven't tried it though.
 
Plastic welds can be fairly strong. I guess that is what the poster above is suggesting.
 
What kind of joints, i.e. lap or butt joints? Lap would be stronger, and a solvent glue as Cliff_J mentioned would be sufficient.

Plastic welding is a possibility - but I am not sure of the experience with PVC sheet or plank.

You might try comparing bond strength with the two methods.
 
marine grade

If its for a boat you intend to use, you should check into a marine grade adhesive.
