Use only on PVC and CPVC plastic. Read WELD-ON® Installation Guide, Product Bulletin and SDS.
Cut pipe square and deburr. Clean and dry joining surfaces.
Check dry fit. Fitting should go over end of pipe easily but become tight about 1/3 to 2/3 of the way on.
Use a suitable applicator at least 1/2 the size of pipe diameter, for larger sizes use a swab or roller. Do not use a rag as repeated contact with skin may cause irritation or blistering.
Apply primer to inside of fitting equal to socket depth, without delay coat pipe end up to socket depth until soft. Apply again to fitting socket. Avoid puddling.
On bell end pipe, do not coat or allow primer to run beyond socket depth.
To check penetration, scratch surface. Re-coat if necessary. Actual time for priming action is affected by pipe diameter and temperature.
Immediately while surfaces are still wet, apply appropriate WELD-ON® cement following directions on cement can.
