Buying Guide Of The Best Primer For Asbestos Siding

With three different products and a vast amount of information, it’s normal to get confused. Hence we’re here with our buying guide to help you get rid of any confusion. 

Here, you’ll get all the necessary information about the key buying factors needed at the time of buying. And, if you remember all of these factors, you can even recommend some products to the people around you. 

Sounds interesting? Let’s begin- 


Yes, the application is an important factor when considering buying the primer. Then again, application also remains one of the easiest things to do. 

But, some primers aren’t so easy to apply. Moreover, some of the primers make the whole surface messy whereas the other ones don’t mix well with the paint. 

So, before buying them, check out the information on the application. Here, make sure that the primer can be applied with rollers. And you can use the roller for painting kitchen cabinets to prime the surface as well.   

Adhesion & Bond Formation

A primer is used so that it helps the paint in sticking to the surface. So, when buying the best primer, make sure to check the bond capability and adhesion. 

Here, you’ll need to look at the surfaces at which the primers bond as well. If you have a glossy surface then go for the ones that work well on these surfaces. Because of the adhesion factor people often hesitate to texture over paint.

Interior & Exterior Surface Compatibility

Yes, it’s essential that your primers can work well on both surfaces. Otherwise, you’ll have to buy different products for different surfaces. 

From the list, you’ve already seen a couple of products that have this factor in them. So, when you’re buying the best primer for yourself, check this factor out. In the end, this factor will save time and money at the same time. 

Color Factor

Here, the factor isn’t about the color of the primer only. At times, the color of the primer changes the color of the paint. Moreover, it can hide the color of the paint as well. 

So, before you buy the primer, you’ll have to check whether the color of the primer interferes with the paint. 

In my own experience, it’s better to go for the ones that have a clear color. Here, the clear color of the primer won’t hide or change the color of the paint by any means. 

Drying Time

When working with the primers, it’s always better to consider the drying time. If you don’t have any idea about the drying time then you’ll mess up your work completely. 

Besides, painting over semi-dry surfaces won’t result in beneficial work at all. Hence, it’s better to consider and know about the drying time. 

Other than this, the drying time varies from one product to the other. So, you’ll need to check the products accordingly.
