What type of applicator should be used to apply the solvent cement?
Most solvent cements come with a dauber included in the can. This dauber is typically one inch in size and be used to apply cement to pipe sizes up to 2″. Installer should check the dauber size as different size cans can have large and small daubers. The dauber size should be as close as possible to the diameter of the pipe. (Using a dauber which is too large in size can cause the cement to puddle in the fitting causing potential solvent stress cracking.) Above 2″ diameter, a brush the pipe diameter can be used, rollers should be avoided for the smaller sizes ( thru 3). For above 3 diameter, it is recommended that the installer consult the manufacturers installation guide for possible applicators and sizes.
