Do I Need to Prime Drywall Before Tiling? (Answered)

Are you thinking of tiling your drywalls? However, are you wondering whether or not you should prime drywall before tiling?

Nevertheless, priming drywall before tiling can work like wonder due to the myriads of benefits that result from following an additional process of priming.

Do I need to prime drywall before tiling?

You should definitely prime the drywall before tiling because it can result in long-lasting adhesion of tiles, versatility, and increased functionality. By putting a good primer before tiling, it can help prevent all moisture, molds, mildews, imperfections, and so on.

Putting a layer of primer before the tiling process is a very important step to follow due to the myriads of benefits of using primers. Additionally, it works really well to work as adhesive to tiles and in removing the imperfections of drywalls. 

Primer is an important element that works as a good absorbent. It is water-resistant that helps to prevent molds and mildews and also provides sound and heat insulation. 

Can you put tile directly on drywall?

Technically, you can put tiles directly on drywalls however this highly depends on the condition of the drywall. In addition, if your drywall is smooth and has fewer imperfections such as ridges, stains, scratches then it may suffice to directly put tiles on drywall. 

However, even after that, you need to make sure to clean the drywall thoroughly and if the drywall is an old one, then you need to be extra careful while installing tiles. 

Moreover, you also need to clean out all the grease and you also need to use a thin-set adhesive to properly apply the tiles directly on drywalls. 

What happens if you don’t prime before tiling?

Priming before tiling will make very significant changes therefore, being knowledgeable about the consequences can help you make wiser choices. 

Decay of the Adhesive: 

If you skip this integral part of priming before tiling, chances are the adhesive on the drywall will be decaying.

Primer has polyvinyl acetate in it which helps to bind things together and in the absence of this primer, adhesive starts to become weaker as the constant sun and heat wear off the adhesive. 

Absorbent Drywall:

Drywall is naturally very absorbent and when you will be adding glue on the tiles to place them directly on the drywall, chances are the drywall being very absorbent will absorb the solvent in the glue.

Consequently, this can cause a lot of problems meaning the adsorbing of the tile glue by the drywall can cause the adhesive to fortify and can also result in defective adhesion. 

Growth of Mold and Mildew:

Another major disruption that can result from skipping the priming process is that it can cause molds and mildews to grow abundantly on the drywall.

In addition, not priming before tiling can also cause the drywall to be moisture ridden which is the perfect environment for molds to grow. 

Imperfections Prevails: 

One of the major problems that result from not priming before tiling is the prevalence of imperfections. Drywalls have so many rough ridges, scratches, stains, and so on and these types of imperfections can hamper the adhesion of tiles to the drywall.

In addition, the usage of primer works as an additional layer that remedies all these imperfections which will result in good adhesion of tiles. 

Moreover, primer works as a kind of adhesive that enhances the functionality of the drywall, and skipping this essential step will result in poor adhesion. 

What should I prime my walls with before tiling?

Although whether you should prime walls before or not may be an additional option, it still is an important step to follow. And there are different arrays of things that can be used to prime the walls before tiling.

PVA Primer:

One of the best things you can use is the good ol’ PVA primer which is anti-porous, heat resistant, moisture resistant and this PVA primer is specially made to be used on drywall.

Drywall Sealer: 

You can also use drywall sealer as a secondary solution. The drywall sealer has binders and resins in it which help to set the drywall for tiling although it is not as effective as a primer.

Thin Set Adhesive:

A thin-set adhesive that has better bonding agents can imitate some of the qualities of actual primer but not as elaborately as classic primers.

Can you tile on painted drywall?

You can definitely tile on the painted drywall. Drywalls are generally made with gypsum material which is a very useful material to install under tiles. 

In addition, if you happen to renovate your home or if you are upgrading it, then you do not have to remove the whole painted drywall rather you can just reuse it. 

You can just use 120 grit sandpaper to roughen up the painted drywall and to make sure that the shiny paint is scrubbed off of the drywall. 

After that, you can just follow the usual necessary steps to install the tiles which will include putting a layer of primer, re-sanding the drywall, and lastly, placing the tiles. 

What type of drywall goes under tile?

There are myriads of drywalls that you can install under tiles. Drywalls are very effective and inexpensive. 

First of all, you can use the green board under tiles. Greenboard is made out of recycled materials which make it very sustainable and environmentally friendly. 

This will be a perfect option to install in the shower, bathroom, kitchen, bedroom, living room, and so on. Green boards are also used under ceramic tiles as backer boards and this is also a perfect option to choose for inhibiting all the mold growth. 

Secondly, the blue board which is another type of drywall also goes under tiles. If you are on a budget, then choosing a water-resistant blue board will suffice. 

Thirdly, another great option that goes under tiles is a cement backer board which can be an excellent choice to choose due to its versatility and functionality. 

Is drywall sealer the same as a primer?

The drywall sealer is not the same as the primer. Drywall sealers are somewhat low in pigments but on the other hand, primers have a high consistency of pigments in them. 

Additionally, drywall sealers have a higher amount of resin but conversely, the opposite is true for primers cause primers to tend to have low resin quality. Drywall sealer helps to subvert the absorption of paint but this feature is missing in the primer. 

Moreover, drywall sealers have more binders in them and sealers can also fill out the pores on the surfaces. However, drywall primers do not have binders in them, and will not give you a very smooth and flawless finish even after the application.

Furthermore, primers are mainly for creating flat sheen surfaces and this causes the paint to adhere to the surface pretty easily, conversely, drywall sealer helps to fill out all the ridges, holes, stains, and so on. 

Will primer hide drywall imperfections?

Primers have a glue-like consistency and due to their consistency, they can adhere to the wall very nicely and it is a very essential element when it comes to hiding the imperfections of the drywalls. 

Your drywall may have rough ridges, scratches, stains, holes and you can use a long-lasting primer to remedy this situation. 

In addition, primers hide the imperfections and patch up the holes and stains in drywalls elaborately. In addition, you can also fill out the bubbles and caps on drywalls with the help of a primer.

Additionally, primers also help to remove all the imperfections like grease, rust, ridges, water damaged marks, and so on. Primer on drywalls can also help to removes odors, moisture, mold, and mildew. 

However, you still may see tiny bits of imperfections lurking around your drywall due to the priming process but these imperfections are very trivial. 

Do you need to sand after priming drywall?

If you are already done with priming the drywall, then you can follow an additional step of sanding the drywall to enhance the beauty. Although sanding drywall after priming is not mandatory, nevertheless, it can produce some positive results.

In addition, after priming the drywall, you can just gently sand the wall with 150 or 180 grit sandpapers. Moreover, placing primer on the drywall can result in several tiny ridges and imperfections. 

Consequently, sanding the drywall that has been primed can result in smoother finishes and the elimination of all the imperfections which will really help to create a perfect base for the tiles. 

However, if you are worried about all the dust resulting from doing another round of sanding, then you can just use a vacuum to clean up but priming before tiling is a must and a fruitful thing to do. 

Final thoughts:

To sum up, nothing can beat the effectiveness of following an additional step of priming drywall before tiling. Priming drywalls before the process of tiling helps to remove stains. rough ridges scratch, and can also help to increase the surface energy.
