How Long Does PVA Sealant Take to Dry?

Are you willing to know how much time does PVA sealant take to dry so that you can move forward towards further process? If yes, you have to read this guide containing detailed information about the time taken by PVA sealant for proper drying up.

This component is generally used as an addition to cement and plaster to furnish additional stability and adhesive to the mixture. It is necessary to give sufficient time to the sealant to get dry to provide the desired results.

Hence, it is essential to know the exact time it gets dry and the reasonable conditions required for it. Keep reading to get all the information about things associated with the PVA sealant drying up process.


How Long Does PVA Sealant Take to Dry?

How can you make PVA glue to dry fast? When you are using PVA sealant, it’s common to see that it takes about an hour to completely dries off. It isn’t much of an issue when you are in no hurry but what if you are short on time and you want glue to dry fast?

Then, there are some tips that you can follow and lessen the time by minutes for when it will dry. Those tips are as follows:

  • If you want the PVA glue to dry faster, then its recommended that you keep it in a well ventilated or open area. Exposure to air can speed up the process for the glue to stick on the surface.
  • If you apply a smaller amount of glue on the surface/object, it will automatically lead to wanting little time to dry up.
  • Applying only the required amount of glue to stick the object/ material will eventually take less time and dry at a faster pace.
  • To speed up the process, you can turn on the fan and direct the blowing air coming from the fan to the object/material. Exposing the object’s surface to continue blowing air will tighten the liquid glue and dry in quick time.
  • You can turn on the oven and warm up the air temperature that will quicken up the drying, and you can have the object glued in fewer timings.

Is PVA Waterproof After Getting Dry?

The primary use of PVA is that they are used on wood and thus are known as wood glue too. Albeit most of the PVA glue used for industrial purposes are water-resistant to grade 2. PVA glue can bear several rounds of drying/soaking without harming the sealant joint.

However, they are not waterproof. So if not waterproof, then how much time sealant takes to go rigid?

Under normal circumstances under average room temperature, the glue joint takes around 20- 30 minutes to dry enough to be handled and engaged in any movement. But if the surrounding is chilly, then the drying process could take around an hour or so.


PVA Sealant on Concrete

You can also use a PVA sealer for providing adhesive coats to the all-new concrete material. It is advantageous and can be applied easily through a paintbrush after cleaning the concrete properly. For concrete also, you have to make use of the clamping to set glues.

It requires around 30 minutes to one hour to allow the glue set on the concrete. Further, the curing time is approx. 24 hours. You must wait and leave the concrete till the glue dries up.

You have to use a sealer that is designed especially for the protection of concrete moisture. It usually comes in two parts that you have to mix before applying the same on the concrete floor.

We highly recommend you pay special attention to the corners and edges of the flooring. It will ensure to block the cracks from which extra moisture can get into it.


How Strong is PVA Glue/Sealant?

Now, the question arises of how strong is this PVA sealant. It is good to know about the glue’s potential to make fair use of adhesive on different materials. PVA glue is much better than other bonds in terms of strength when it comes to mechanical resistance.

It provides appropriate stability to the material and can be used to obtain the best results. However, there is another glue that you can use for extra strength. Instant bond is one of the quickest and high-performance cyanoacrylate adhesive glue.

When you use it collectively with an activator spray, it will reduce the bonding time to a few seconds that can be a remarkable 5000lb psi bonding strength.


Effect of Weather on the PVA Sealant Drying

Weather conditions also affect the drying process of PVA Sealant. It is even one of the factors that affect the time taken to dry up of PVA Sealant. The time varies according to the different weather conditions.

Being a water-based adhesive, PVA Sealant gets dry in warmer air rather than in colder air. Warm air accelerates the drying process and can further reduce the time required in everyday situations.

In the case of excess humidity, the drying process needs a more considerable time due to the adhesive’s slow water evaporation. It further gets quickly dry on materials having pores like fabric and paper. It is because these pores breathe and allow the water from the fabric to evaporate soon.



If you are using a PVA Sealant on different materials, you need to remember the time it takes to dry. Without knowing the accurate drying time, you cannot proceed further, and it can also lead to poor quality results.

So, for ensuring high-quality outcomes, it is necessary to allow the component to take its time to get dry, and you have to wait for that specific period. You must be very careful while using a PVA sealant on concrete for obvious reasons.

Moreover, it is better to evaluate the prevailing conditions and don’t take actions quickly while applying various coats. Hence, you need to understand all these things before using PVA Sealant.
