By following our standard instructions and using a little extra care and patience, successful solvent cemented joints can be made at temperatures even as low as -15°F. In cold weather, solvents penetrate and soften the plastic pipe and fitting surfaces more slowly than in warm weather. Also the plastic is more resistant to solvent attack. Therefore, it becomes even more important to pre-soften surfaces with an aggressive primer. And, because of slower evaporation, a longer cure time is necessary. Our cure schedules allow a margin for safety, but for colder weather more time should be allowed.

TIPS TO FOLLOW IN SOLVENT CEMENTING DURING COLDER WEATHER:

1. Prefabricate as much of the system as is possible in a heated work area.
2. Store cements and primers in a warmer area when not in use and make sure they remain fluid.
3. Take special care to remove moisture including ice and snow from the surfaces to be joined.
4. Use a Weld-On Primer to soften the joining surfaces before applying cement. More than one application may be necessary.
5. Allow a longer cure period before the system is used. A heat blanket may be used to speed up the set and cure times.
6. Read and follow all of our directions carefully before installation.

Although Weld-On cements are formulated to have well balanced drying characteristics and to have good stability in sub freezing temperatures, we do offer a special cement formulated just for cold weather, our Weld-On 727 "HOT 'R COLD". In cold conditions this all weather cement will setup and cure faster than other cements currently available.

For all practical purposes, good solvent cemented joints can be made in very cold conditions with proper care and a little common sense.
