Spears PRIM21-68C-20 Low Voc Pvc Cpvc Primer Clear 1 Pt

Product Description

The SPEARS PRIM21-68C-20 is a clear, low-VOC primer formulated for surface preparation and softening of PVC and CPVC pipe and fittings before solvent cementing. Proper priming opens the molecular structure of the pipe surface, allowing the cement to penetrate and form a fused joint. This primer carries NSF certification for use in potable water systems, making it appropriate for drinking water supply lines. It is packaged in a 1-pint metal can and is regulated due to its VOC content, which means local air quality regulations may affect where and how it can be sold or applied. Licensed plumbers and pipefitters are the primary installers.

This primer is used in residential and commercial plumbing installations wherever PVC or CPVC pipe and fittings are solvent-welded. Common applications include domestic water supply, irrigation, and other fluid-handling systems that call for NSF-rated materials. The low-VOC formula reduces harmful emissions during application, which is particularly relevant in enclosed or poorly ventilated work areas. The clear color leaves joints with a clean appearance, which can be important in finished spaces where pipe runs are visible.

Installation Notes

Apply this primer only in well-ventilated areas and follow all applicable local and federal VOC regulations. Licensed plumbers should apply primer using the dauber or applicator supplied with the can, working quickly before the solvent flashes. Do not use this primer as a substitute for solvent cement — it is a preparatory step only. Shut off and depressurize any existing system before disturbing connections, and allow fully primed and cemented joints to cure per the cement manufacturer's specifications before pressure testing.
