How to Use Solvent Cement?

Use Hydro & Seal products within three years of date stated on the can, shake well before use, and do not use if gelled.

1)  Use a proper cutter and cut the pipe as squarely as possible.

2)  Deburr and chamfer the outside edges of the pipe to 10 to 15°.

3)  Clean joining surfaces.

4)  Check the pipe and fitting for dry fit. The pipe should enter the fitting easily but become tight about one-third to two-thirds of the depth.

5)  Apply primer to internal surface of the fitting and outer surface of the pipe for the entire cementing length using the dauber attached to the lid. Allow the surfaces to rest for a few minutes before applying the solvent cement.

6)  Apply a thick, even layer of solvent cement to the outer surface of the pipe, and a thin, even layer to the internal surface of the fitting for the entire cementing length.

7)  Insert the pipe into the fitting immediately until the pipe is properly seated inside the fitting. You need to assemble parts in a single movement while solvent cement is still wet. Reapply cement if not wet. Rotating both parts a 1/8 to 1/4 turn while inserting the pipe into the fitting helps create a more uniform layer of solvent cement.

8)  Apply pressure to the joined parts for 30 seconds to ensure initial bonding and to avoid push-out.

9)  Wipe off excess solvent cement from the outer surfaces.

10)  Do not pressure test until cement is fully cured.

The average set time and cure time for solvent cement is as follows:
