What is the Best Sealant for PVC and Concrete?

Last Updated on June 20, 2023

When it comes to sealants for PVC and concrete, the best option is a high-performance silicone-based sealant. A silicone-based sealant offers superior adhesion, flexibility, and durability when compared to traditional acrylic or latex-based sealants.

It will provide a waterproof barrier that prevents water, dirt, and other contaminants from penetrating into the substrate and creating damage. 

In addition to being highly resistant to weathering and UV radiation, silicone-based sealants are also highly resistant to temperature fluctuations. This makes them ideal for use in areas with extreme temperatures, such as external basement walls or outdoor patios. 

They are also non-toxic, so they won’t damage vegetation or contaminate the environment when used correctly. When applied correctly by an experienced installer, a silicone-based sealant can last up to 15 years before needing a replacement application. 

This means you can rest assured that your investment in something like concrete or PVC will be protected for many years to come.

Best Sealant for PVC and Concrete Buying Guide: What to Look for?

Best Sealant for PVC and Concrete Buying Guide

Choosing the right sealant for PVC and concrete is an important task, as it will help make sure that your projects last long into the future. Sealants are designed to protect the materials they are applied to, so it is essential to choose one that will provide the best protection and longevity. 

Before selecting a sealant, it is important to consider factors such as environmental factors, surface preparation, cost-effectiveness, safety considerations, application methods and more. 

By taking the time to research each of these elements thoroughly before making a decision, you can ensure that you find the best sealant for your PVC or concrete project. When selecting a sealant for PVC and concrete projects, one should consider environmental factors such as temperature range and exposure to sunlight or water. 

For example, some types of sealants may be affected by extreme weather conditions while others are designed specifically for high temperatures or moisture-prone areas. 

Additionally, some types of sealants may require special primers before being applied. It is also important to take into account any surface preparation required before applying the sealant; this could include cleaning or filling cracks in the material beforehand. 

Furthermore, when deciding on a type of sealant it is important to consider its cost-effectiveness; different products can vary significantly in price based on their application methods and ingredients used.

In addition to budgeting concerns, safety must also be taken into consideration when choosing a sealant for PVC and concrete projects; always read product labels carefully before deciding which product you should use. 

Some products may contain hazardous chemicals which can cause health risks if not handled properly so do your research thoroughly beforehand. 

Lastly, depending on your project’s size and scope you may need to purchase additional tools like caulking guns or putty knives; these items may add extra costs but can be essential for proper application techniques.

By taking all of these factors into consideration when selecting a sealant for PVC or concrete projects you can ensure that you get the best quality product possible at an affordable price while still adhering to safety regulations. 

Investing in good quality products now will result in longer lasting projects in the future so make sure you do your research before making a final decision!

What sealant sticks to PVC?

What sealant sticks to PVC

The best type of sealant to use on PVC is a polyvinyl acetate (PVA) or polyurethane-based product. These types of sealants are designed to provide superior adhesion to PVC, and they can be applied either with a brush, roller, or even sprayed onto the PVC surface. 

PVA and polyurethane-based sealants offer excellent weather resistance and flexibility, making them ideal for use in harsh climates. Additionally, these sealants can also provide an additional layer of water resistance as well as UV protection from the sun’s harsh rays. 

Other types of sealant that may also be used on PVC include silicone and acrylic-based products.

Can you use Gorilla epoxy on PVC?

Gorilla Epoxy is specifically formulated for use on metal, wood, glass, ceramic, stone and more – but it is not designed for use on plastics such as PVC. This type of epoxy is not suited for this purpose because it does not have the necessary adhesive strength to bond effectively with the plastic material. 

It could potentially cause damage due to its chemical composition which includes solvents that will erode plastic over time. As such, we do not recommend using Gorilla Epoxy on PVC surfaces.

Does epoxy adhere to PVC?

Does epoxy adhere to PVC

Epoxy can adhere to certain types of plastic including polyethylene (PE), acrylonitrile butadiene styrene (ABS), low-density polyethylene (LDPE) and high-impact polystyrene (HIPS). However, it does not typically adhere strongly enough when used with Polyvinyl Chloride (PVC), which is commonly used in pipes and other plumbing fixtures due to its durability and low cost. 

If you need a strong bond between two pieces of PVC then an alternative would be required; for example contact cement or solvent cements are better suited for this application than epoxy resin.

Can concrete go around PVC?

Yes, concrete can go around PVC piping without any issues as long as there is proper curing time after pouring the concrete. 

The curing process should take at least 28 days before any kind of pressure or stress is put onto the pipe or structure as this will ensure that the concrete has reached its full strength prior to being exposed to any kind of strain or force. 

Additionally, it is important to make sure that the concrete is completely dry before it comes into contact with any type of material such as plastic or metal piping so that it does not cause any corrosion issues down the line.


When it comes to protecting your investment in PVC or concrete surfaces from weather and other elements, using a high performance silicone based sealant is your best option. 

Not only does it provide a strong bond between the substrate material and any protective surface layers you may apply over it; but its long lasting properties and resistance to temperature extremes make it perfect for outdoor use where the elements can cause problems quickly if left unprotected. 

Additionally, its non-toxic makeup ensures that it won’t damage vegetation in close proximity or leach chemicals into the environment once applied making it an ecofriendly choice of sealant as well! 

With all these benefits combined into one product, there’s no doubt that investing in this type of high performance siliconized drywall compound is worth every penny spent!
