We have designed a list of features for you to check before deciding which mold-killing primer to buy. You can therefore make the correct decision that suits your demands.
The first feature you should always consider before deciding which mold-killing primer to buy is its guaranteed durability. To get the value for your money, we suggest that you get a primer guaranteed to last longer.
We recommend that you consider the endurance of the primer and its effectiveness to resist the growth of mold and mildew. In many cases, homeowners have used primers that outlast their ability to protect their walls from the growth of mold and mildew.
Therefore, implying that your wall having decent paint does not mean it will always resist mold and mildew. Our advice is to pay special attention to this specific detail to know when to prime and repaint.
Method of application
It is very important to consider the method you will use to apply mold-killing primers, considering that some areas may be greatly confined. You can opt to use rollers when applying on delicate surfaces or paintbrushes for rough or hard-to-paint perceived areas.
Nevertheless, you can opt for the spray-on technique as some mold-killing primers are in a spray can that is convenient for this technique.
It helps greatly to know the area a certain primer or paint can cover per unit. The more it covers, the better.
This knowledge is important as it determines how much you can prime with what is within your budget. For instance, it is advisable to prefer a primer with area coverage of 300 square feet per unit to a primer that covers only 150 square feet per unit. However, this will depend on the porosity of the surface you intend to apply on.
Nature of your project
The nature of your project will determine the kind and size of the mold-killing primer you need. The primers come in handy in different kinds and sizes, implying that you can buy them depending on the need of your project.
To know the area the primer will cover, you should check the user manual of the product labeled at its side.
It is good to check on your area’s availability before deciding whether you should purchase the product. The primers are available in both physical and online stores.
Nature of the product
It would be best if you considered such aspects as the composition of the primer as it dictates how the primer performs on various surfaces. The primer should naturally provide a protective film that resists fungal growth, which leads to the rearrangement of wood grains.
As evident in the above, the most suitable composition recommended best mold killing prime should be oil-based and water-based.
A mold-killing primer and mildew-resistant paint should either resist water or be waterproof. It would help if you considered how much moisture it can sustain.
It would be best to consider waterproof and water-resistant primer because it prevents your walls from excess moisture and avoids damages that can cost you a lot later. If the moisture gets to the wall surface, then mold and mildew grow, causing bad stains and can cause worse health issues too.
We recommend a waterproof mold-killing primer for bathrooms, laundry rooms, or areas in the house with high moisture levels since it prevents the walls from seeping the moisture.
Requirements of application
These primers vary in their application requirements. Some primers such as KILZ 2 Multi-Surface Stain Blocking require that you clean the surface before application to ensure there is dust, grease, or mold.
However, other primers such as Rust-Oleum 02754 white Perma Interior Paint do not require cleaning before application considering you can apply on any service.
If your surface is not water-resistant and you are sure it will be exposed to the elements, we recommend that you prime before painting. Priming will help to give better adhesion to your surface. It ensures the durability of the paint and offers extra protection for your painted surface.
It is important to note that some mold and mildew-resistant paints are self-priming, and this implies that you will not have to prime before painting. Self-priming paints are meant to perform both the function of painting and priming. These paints will greatly save you time and money.
The time taken by primers and paints to dry may vary greatly between the products. We can confirm that both latex-based and water-based primers take a short time to dry compared to the oil-based ones.
Although paints may appear dry to the touch in a short time, homeowners are advised to wait even longer before spreading the topcoat. You should always check the label on the primers and paints for the same drying periods.
What causes mold?
Mold commonly grows on dead organic bodies or materials. It starts to form mold spores which are transferred from one place o another by a factor such as wind or people and can find themselves in your house through an opening along with air conditioning systems.
Our research shows that these mold spores are extremely small, and they cannot harm humans on their own. For them to grow, they will require food (organic materials), oxygen, and water. It is impossible to avoid oxygen, but the question comes to rest.
Mold will feed on any organic material with carbon atoms, including oil, paper, wood, and food leftovers. It is good, however, to note that paint contains such organic atoms.
Moisture is unavoidable, too, as long as high humidity areas like bathrooms and laundry rooms. If the mold spores we are talking about find themselves in an environment with these three components, then there is no doubt they will grow.
Is mold harmful?
Mold is not as harmful as people think. You can live with few mold outbreaks without them harming you. However, this does not imply that people will not find mold ugly and horrible in your house.
While small mold spots may not cause concern, larger spots will raise the alarm to people. They may cause your eyes and skin to itch and your nose to snuff. Research shows that mold may trigger asthma symptoms, and continuous exposure to larger amounts may cause fever and difficulties in breathing.
There have been speculations and claims that it causes memory loss, but it is yet proven. While mold may not cause long-term health issues to homeowners, it is not something you would want in your home.
How can I prevent mold growth?
You would not like mold to come back in your home after you have removed it. Right? There is plenty you can do after applying mold-killing primer to prevent mold from growing in other areas.
The first thing you can do is to keep low humidity levels in your house. We recommend that you keep our windows open if possible and use an extractor fan whenever you shower. You may also use a dehumidifier as it serves well in high humidity areas.
It is also a good thing to ensure a continuous flow of fresh air in your house as it will dry all the wet spots in your house, leaving no chance for mold to grow.
After doing this, you are experiencing recurring mold growth, then you should check for other problems. You should check if your pipes are leaking and if there are any other cracks. If you do these things, then the chances for mold growth will be minimal.
Does mold-killing primer work?
We have tested to confirm that the mold-killing primers recommended in this post are highly performing in resisting mold growth. However, it is highly recommended that you spread mold killing solution before painting to get the best results.
All the mold-killing primers vary, and you should consider what you are buying. Cheap mold-killing primer may not probably be the solution to your problem as it may not effectively fight mold growth.
The primers we have recommended for you above have been carefully chosen and proven effective in various environments. You are the one to decide which one best suits your needs. If you choose well, then you will realize the magic that the primers perform to prevent mold growth in your house.
How many coats of mold-killing primer should I apply?
We will answer your question considering several factors, such as the wall material, the paint color, and the kind of primer you are using. While on some surfaces, you may need various coats, on other surfaces, you may need only one.
We would recommend that you assess after every coat of primer dries. If you are painting over a wall painted before, you may need only one coat. However, you may need various coats if you are painting over plaster or unfinished drywall.
The amount of paint absorbed on the surface will determine the amount of primer you will need, and it will help you ensure there is no bleeding into the paint and prevent any stains. You can assess how the primer has adhered to the surface.
The outcome of a good primer can change everything for a topcoat. If the surface you intend to apply is well-primed, you may only need one primer layer. If you think it is not enough, then you may add one more primer coat.
What should I use to kill black mold?
For black mold, we would recommend vinegar which has proven to kill 80% of mold and is highly effective. It is the best choice for those searching for a safe, non-toxic cleaner. In food preparation areas such as kitchens, you can use white vinegar.
To apply it, you can mix it with water in equal measures. You are lucky if you have an old spray bottle, as this will simplify your work. It will be easy to apply any white vinegar, and therefore you can grab the one you can afford in your nearest store.
However, if the mold-killing primer you are using is high-performing like the ones we have recommended in this article, then you should worry less about removing the entire mold. So long as you apply your vinegar solution, then leave the rest to the primer. It would be best if you considered vinegar when removing black mold.
Which primer should I buy? KILZ or Zinsser?
We have looked at various options in this article, with some being KILZ primers and others being Rust-Oleum Zinsser primers. We are greatly excited by the high performance of all the primers we have recommended to you. If you opt for either primer, you are sure to get the best results.
We have observed that Zinsser appears to have many primers that are particularly designed to resist mold growth. Although KILZ too has many excellent primers, many of them do not resist mold.
So now which one should you buy? Generally, we would say that it is an equal score since they are great performing primers that deliver the best results. However, as you can see, our top pick is Zinsser primer; we thought they were the best compared to other mold-killing options.
Can I paint over mold-killing primer?
We have recommended to you all these paints to ensure your surface is effective before you paint. Therefore, the answer is yes. These primers will hinder mold from growing and give you a chance to apply your topcoat. In some cases, if you have used a certain variety of primers, you will need a particular kind of primer, so we recommend that you should always double-check.
We would recommend that you follow instructions as labeled in the primer since, in some primers, you will need more than one coat. The extend of the mold will also determine the topcoat you will use. Do not be surprised if a mold-killing topcoat is recommended to you.
What do professionals recommend to kill mold?
