Three Mistakes to Avoid When Using Solvent Cement

Solvent cement is a quick and easy way to fuse PVC pipe and fittings together. When applied to pipe and fittings, the cement melts a thin layer that solidifies after being put together, forming a seamless, waterproof seal.

But there’s no room for error—if you’ve made a mistake, you’ll need to cut off the piece and start again. Common mistakes include working with solvent cement on the wrong days, using too much or using too little.

If you try to work on the wrong day, you may not see success with your solvent cement. What’s the wrong day? A hot, windy day speeds up evaporation, causing the drying time to decrease, sometimes leaving you with just seconds to weld the pieces together.

Using too much solvent cement can cause the PVC to dissolve to the point of weakening the joint, lessening the integrity of its waterproof capabilities.

However, if you use too little solvent cement, the pieces may not be fully welded together, which may lead to leaks or other problems down the road.

Try these three solvent cement options available at your local Ewing store for your next project.

PRIMG Prod IR Weld On 905ECOWeld-On® 905ECO™ is the first eco-friendly cement with 15 percent less solvent emissions. As a sustainable solution from Ewing, this solvent cement option gives you the same results as other medium-bodied, fast set PVC cements with fewer odorous fumes.


PRIMG Prod IR Red Hot Blue GlueChristy Red Hot Blue Glue is known as the original blue glue. It’s quick to bond PVC pipe and fittings, helping you be more efficient and increase jobsite productivity. The Red Hot Blue Glue works in wet, dry or humid conditions and can be used without a primer (where codes permit).


PRIMG Prod IR Weld On 705Weld-On® 705™ PVC cement is a high-strength formula. It can be used without a primer on non-pressure systems (where codes permit).

    Shouldn’t it be stated that we dont glue pvc pipe & fittings, you fuse them with the glueing process…

    How can using too much solvent cement weaken the fitting? It will harden on the inside and outside of the fitting and add thickness, not reduce thickness. Wouldn’t this strengthen the fitting?

      Mainly this becomes an issue when excess solvent cement drips into the pipe. The solvent actually softens the pipe and could eventually cause cracking. If the excess is pushed out to the exterior that shouldn’t be a problem, because the solvents will evaporate more quickly. Here’s some more information about the issue of excessive cement use:

    I didn’t hear it mentioned but I don’t believe gluing dirty pipes and fittings is a good idea either. Heavy dirt contamination can’t be good and is an issue you should watch for especially when doing repair work below ground level in a trench.

    that’s it? too windy too much or too little?

      When it’s windy, the solvent cement tends to dry faster which means you have less time to weld the pieces together before it dries. It’s just a matter of keeping an eye on the weather if you find that you’d like more time to work with the pipes and fittings.

    The other label warning is if temperatures are below 60 degrees then curing takes longer

    Oh, what? Too much will weaken the pipe? I should’ve thought of that. I mean for anyone who made that mistake and put the pipe under something like concrete curbing, that’s going to be a painful fix, but necessary nonetheless. Thanks for sharing!

    The article which is provided by you is very nice and understandable

    I am installing a 6 port actuator for an in floor cleaning system. Because I have to glue 6 pipes simultaneously I need a glue that does not set up quickly as I only have one shot to get it glued and set in place without a weak joint. Which glue would you recommend?

    • Robyn Hazen November 1, 2021 at 9:26 am #

      Hi Chip – There are glues listed as slow setting, which typically means they allow for more working time. However, your best bet is to contact your local Ewing branch for details about your specific project. Not only will they have insight about the various products available, they’ll also have information about tips and techniques to help you use it to complete your project. Here’s a link to our Locations page if that helps you find the store closest to you:
