FAQ

How do you open a tube of Liquid PVC?

Liquid PVC has an aluminum seal at the top of the tube. That seal must be punctured for the liquid to flow properly. We recommend that, after the cap and nozzle are removed, and the red ring is thrown away, that the aluminum seal be completely punctured with a paperclip or a sharp object to allow the liquid to flow easily. Then the cap and nozzle can be put back on the tube. If you need a larger bead, the nozzle can be cut with a knife or scissor.

How long do you guarantee your product?

Unopened, Liquid PVC can last up to 1 year beyond the date stamp. Depending on the weather, once opened, the solvents can evaporate causing the liquid to become less effective. That is why we recommend always using a fresh tube for each job. If you are only using small amounts, it may be best to use the smaller tubes to prevent the Liquid PVC from thickening between jobs.

What are some uses for Liquid PVC?

Liquid PVC is designed for vinyl window frames and other hard PVC products like vinyl fencing, siding and gutters.

Can I use Liquid PVC on flexible vinyl?

When cured, Liquid PVC becomes hard. It is made for hard PVC products like vinyl windows, vinyl fencing or vinyl siding. It is not recommend for flexible PVC like automotive vinyl dash boards, etc.

What can cause the crimp to fail?

Like all aluminum tubes, mishandling the tube by squeezing it with too much pressure can cause the crimp in the back of the tube to fail.
To make sure the content flows easily:
1. Make sure the seal at the top of the aluminum tube is completely opened.
2. Squeeze from the bottom toward the top for best results.
3. Always use fresh tubes. Once the tube is opened, the evaporation of the solvents can cause the contents to thicken in a short period of time. This can make it harder to squeeze out of the tube. We recommend using a fresh tube of Liquid PVC for each day. 
4. If you use the same tube on multiple jobs remember that once the tube is open, the upper area can dry quickly causing the nozzle to clog. The nozzle and the opening to the aluminum tube needs to be cleaned after each use.

Does Liquid PVC stick to wood, aluminum or fiberglass?

No. Liquid PVC is a PVC vinyl weld. Our formulation only works on polyvinyl chloride (PVC). It will not adhere to wood, aluminum, fiberglass, glass or plastics like polystyrene, polyurethane, nylon or plastics that contain silicone.

Does Liquid PVC stick to paint?

Very few paints are made from PVC. Therefore, Liquid PVC will not stick to most paints. For proper adhesion, we recommend removing all paint, silicone and other contaminates before applying Liquid PVC.

Can Liquid PVC be painted?

Yes. Once completely cured, our formula has the same consistency as the vinyl in vinyl window frames. Anything you can do with the vinyl window frame can be done with Liquid PVC. It can be painted but only with paints that are designed to adhere to PVC. Caution: once PVC is painted, it most likely will need regular maintenance similar to painted vinyl siding.

How can holes be filled with Liquid PVC?

We recommend fixing holes using our hard stock in our PVC Quick Repair Kits. For small holes like nail or screw holes, put Liquid PVC in the hole, then insert slivers cut from the hard stock. Apply Liquid PVC over the hole. When cured, shave and and sand with our Shine-It Kit until smooth. For larger holes, overlay hard stock over the hole. Weld with Liquid PVC and seal the edges. Liquid PVC will shrink as it cures. Several layers may be needed. Do not use caulking to fill holes. Liquid PVC will not adhere to caulking. Caulking can fail and cause water infiltration.

 What is my window color?

Our chart on the About Page shows our available colors of Liquid PVC based on the window manufacturer. We only have three hard stock colors available in our repair kits. An exact color match is near impossible. There are too many variables.

 At what temperature can I use your product?

We recommend the temperature be between 45º F and 95º F. Cold temperature will cause slow curing of our product. High temperatures will cause it to dry too fast.

How long does it take to cure? 

Depending on the temperature, it skins over within 1 to 3 hours and is dry to the touch. It usually takes 24 hours to fully cure. Once fully cured, the window can be handled as normal.

 Do you sell window extrusions or new windows?

No. We only manufacture products to help repair damaged window frames. Window extrusions are proprietary. Contact your window manufacturer if you need new or replacement windows.
