    Chemical Welding Guide - Layfield

    THF works very well on most PVC products but is usually limited to temperatures above +10°C (45°F). Below this temperature heat must be applied to facilitate the evaporation of the solvent. THF evaporates completely after the weld has set and residue is undetectable. THF is the most common solvent in use on PVC liner materials.

    Can I thin thick PVC cement with primer? - Home .

    PVC cement works, in major part, by creating a chemical weld between the two pieces. If it has thickened, that means there's less solvent, which means it probably won't dissolve/weld into the two pieces as well. It may "work", but the joint is likely to be weaker than it would be with a fresh can.
