Step 2:Wash the floor with detergent and water, if you have stubborn dirt like oil or grease you will have to use stronger chemicals to wash it off.

Step 3:Once the floor is dry and ready, it is now time to start diluting the PVA primer. This is done inside a bucket or container

PVA mix ratio: This may vary depending on the manufacturer’s directions. On a general level, the mixing of water and PVA is always 50/50.

Step 4: Use the paint roller to soak the primer from the container and spread it on the floor

PVA Primer vs Standard Primer

PVA primer is mostly known for sealing the surface of new drywall especially when we are painting because PVA primer reduces the level of paint coat you will have to put on drywall, and it is less expensive than the primer.

PVA primer can also be used as a sealant; as you read through, you will see how it is done.

Importance of PVA to a concrete

Concrete is a very porous substance, and having this attribute is where the PVA comes in

  • PVA helps in the bonding of overlay to the concrete just like primers
  • PVA helps to make the concrete dust free 

Does PVA protect concrete from moisture

Yes PVA sealant protects concrete from moisture when it is properly done well.

Does PVA fix powdery concrete?

PVA does an excellent job of fixing dusty concrete after it has been applied to the concrete.

How to fix powdery concrete

  • First, you must have to clean the floor by using a vacuum or brush off the fine dust debris.
  • Secondly, check if there are oil stains or any stains that need attention. if there is, you can use a high-pressure surface cleaner tool to get the stains off. But in the absence of oil or grease, you can just use detergent and water and wash the floor. Then leave the floor to dry before applying the PVA or other standard sealant
  • Thirdly, at this moment we are ready to apply the sealant or PVA sealer. Prepare the sealant that you want to use, if it is a PVA sealer you should begin mixing the substance with water. Then using a paint roller or pump sprayer you apply the sealant to your substrate.

How is PVA used with cement?

To enhance the qualities of cement mortar and concrete products, PVA is often added as an aqueous solution during mixing in modest amounts of up to 2% based on the weight of the cement.

What is UniBond PVA used for

For priming and bonding plaster or for sealing pores in porous surfaces against dust, UniBond Super PVA is the best choice. Insofar as one is permeable, it adheres to the majority of conventional construction components. Utilizable in dry service environments. glue, primer, and bonding aid all in one.

Can I use PVA outside

Regular PVA dissolves with water and is therefore worthless for exterior walls unless you want everything to wash off in the rain. Despite being waterproof, external PVA is still not advised for priming exterior walls.

Do I need to PVA before self Levelling

It is not necessary to use a PVA prior to applying a self-leveling compound. The surface should be cleaned and primed first, though, before you pour the cement mixture on top of them.

How long does PVA glue last

The suggested shelf life for PVA glue is typically a ploy by the manufacturer to avoid liability. Simply put, they will guarantee the quality level for a year. However, if routinely kept at room temperature, most adhesives can last for two years or more.

Can I use PVA glue as a sealer?

It can be used as a high-performance sealer, primer, bonding agent, and dust proofer. PVA sets when there’s good air circulation and dries fastest at room temperature. You get the strongest seal when you clamp the pieces being glued. It’s quick-drying with very high bond strength.

The disadvantage of PVA glue

One of the primary downsides of this form of glue is that most of them are not entirely waterproof, which implies you can’t truly use it as an adhesive in things like boats or anything else that you could put outside.

What is exterior PVA?
