This blog post will answer the question, “Are blueboard fire-resistant and cover topics like fire-resistant properties of blue boards and frequently asked questions related to the topic.
Is blueboard fire-resistant?
Yes, blueboard is fire resistant. When paired with unique jointing and coating techniques, 5mm BLUE BOARD is a robust, durable, waterproof, and fire-resistant exterior cladding system that provides a solid platform for applied ornamental treatments such as rendering.
What Exactly Is A Blue Board?
Blue board is a form of plaster that lasts longer than drywall alone (source). It has a wide range of applications, as long as you utilize it wisely.
While blue boards are more resilient, when they are exposed to moisture, they become less so. You’ll want to bring them along if you know you’ll be away from a water source for an extended period. This step will help your blue boards last longer.
The use of blue boards should be limited to indoors only.
Because blue boards cannot be exposed to moisture, they should only be used inside. Instead of putting them on the exterior of a home or a shed, utilize them inside. While you may add a layer of protection to the blue boards, standard drywall will not suffice if utilized outside of a building.
Inside, you’d be better off utilizing blue boards and adding an extra layer of ordinary drywall to paint or create a seamless effect.
Cement Board, Greenboard, and Blueboard: What’s the Difference?
Here are a few key distinctions between the two kinds of boards.
- Size and composition
- Installation and durability.
- Resistant to Water
I will now elaborate on the guidance given above.
Size and composition
Cement and glass fibers are used to make cement boards. These come in 48-foot and 35-foot sheets with a thickness of 1/2 inch or 1/4 inch.
Green boards and blue boards, on the other hand, are drywall kinds. Gypsum is squeezed between two sheets of paper to make drywall. It was created to take the place of lath and plaster in a building.
Green boards employ moisture-resistant, green-colored paper instead of the regular drywall paper. Blue boards, too, have a blue-colored paper layer that is meant to stick to cement. These boards come in sheets of 48 and 40 feet long and are 1/2 or 5/8 inch thick. Green boards and blue boards, on the other hand, contain gypsum cores.
Installation and durability.
Blue boards and green boards, both constructed of gypsum, are significantly less robust and impact-resistant than cement boards. Cement boards, on the other hand, are much heavier than green boards and blue boards, making DIY installation harder. Cement boards are best put up by specialists.
Resistant to Water
Water-resistant and waterproof cement boards are also available. The green-colored moisture-resistant paper on green boards, on the other hand, is merely water-resistant. Green boards cannot be waterproof since their core is still gypsum. Blue boards are formed of gypsum and are not covered with moisture-resistant paper, hence they are neither waterproof nor water-resistant.
Water-resistance is crucial because water may contribute to the growth of mold and mildew, which can lead to decay and breaking. The way these boards may be utilized is also determined by their water resistance.
Because of its durability and water resistance/waterproof nature, cement boards are best employed as siding outside the home or in damp places within the house, like bathrooms and kitchens. Cement boards are also the finest underlayment for tiles because they provide a flat surface and help the tiles adhere better. In reality, green boards and blue boards should not be utilized as tile backing boards or for wet applications.
Green boards, on the other hand, are water-resistant and may therefore be utilized in moist environments such as un-tiled bathroom walls and basements. They work best in sections of the home where there is a lot of humidity and there is a lot of water spray.
Blue boards are water-resistant but not waterproof, so they should not be utilized in damp environments. Blue boards, on the other hand, should only be used as an underlayment for veneer coat plastering, which is what the blue-colored paper is meant for.
What Are the Benefits of Using Blue Boards?
You have a variety of alternatives for how to utilize the blue board in different situations.
Because of its endurance, construction is an important area of necessity. Because blue boards can bear a lot of strain, they may be used to insulate walls or even floors. There are also ways to overcome its moisture weakness, which makes it even more important in construction. The benefits of using blue boards are listed below:
- The Use of a Blue Board Can Assist in Noise Reduction.
- A firm foundation is provided by the blue board.
I will now elaborate on the guidance given above.
The Use of a Blue Board Can Assist in Noise Reduction.
Blue boards may offer noise-canceling effects due to their thickness. This feature is particularly useful in music rooms and recording studios. It’s especially useful in bedrooms when you don’t want the noise to spread around the home.
Also, blue boards aren’t only for the walls. Plasterboards may be used beneath a flooring to increase their noise-canceling properties. If you use blue boards to cover both the floor and the walls, you may be confident that no noise will go in or out.
A firm foundation is provided by the blue board.
Blue boards give a stable foundation for any room since they can go beneath other drywall forms. If you’re going to employ a bonding agent, be sure it’s a veneer plaster.
Blue boards are designed to attach to that sort of application more quickly and stably than other varieties. You should also use a plaster skim to make your blue board panels less absorbent.
Is there anything else I should know about blue boards?
Other plasterboards, such as green boards, are utilized in a different way than blue boards. Before you use a blue board, make sure you are aware of the following facts:
- Drying times for blue boards are faster than for other types of drywall.
- Blue Boards Can Help You Work More Productively
I will now elaborate on the guidance given above.
Drying times for blue boards are faster than for other types of drywall.
Because of the paper that surrounds the plaster, the blue board dries quicker.
You should be aware of this since, while working with this kind of drywall, you will need to work quickly. You won’t have much success bonding additional drywall or paint to the surface of the gypsum dries too rapidly.
Blue Boards Can Help You Work More Productively
You can complete home or building projects more quickly using a blue board since it dries faster than regular drywall. However, keep in mind that since the paint dries quickly, you’ll need to work at a steady pace.
The faster the drying time might help you meet deadlines or get out of a construction zone faster if you have numerous individuals helping or working with you.
These are just a few examples of how blue boards may be used. They may be used to create more durable wall coverings or to better soundproof the room. They’re particularly useful if you’re short on time since they dry quicker than conventional drywall treatments.
Where can Blue Board Cement Sheets come in handy?
Blue boards are the only drywall sheets that may be taped without any further treatment, unlike other drywall sheets. This makes them much easier to operate, and they’re also incredibly affordable. Because they offer an uncommon form of support system, they’re typically employed in ceilings. Blue board drywall is often used by authorities, such as hospitals and nursing homes, during reconstruction projects because it provides a smooth collision barrier for patients or convicts who wander into adjacent rooms or floors.
The cement sheets are often used during water damage restoration work to provide additional drywalling material to emergency crews until replacement components can be sourced. This might be your best choice if you need something fast yet somewhat sturdy.
Is the blue board water-resistant?
Another advantage of blue boards is that they are waterproof and mildew-resistant, as well as mold-resistant. This makes them ideal for kitchens and bathrooms, which have a lot of water and need to keep moisture levels low. In certain situations, moisture-resistant drywall is suggested.
Blue board drywall has been utilized in submarines, underwater labs, and other similar facilities for this reason. It can withstand the pressure exerted by water or any other liquid, making it an excellent option for retaining walls. When subjected to intense heat, the blue board material does not generate poisonous gas, which may still happen during a fire. Blue boards are often suggested for use in electrical boxes and fuse boxes because of their fireproof quality, which may prevent sparks from igniting a fire.
Blue boards may also be utilized as ceiling tiles if the correct glue is used, such as asphalt or asphalt-based adhesive. Otherwise, your blueboard ceiling might be incredibly combustible, putting your whole family at risk.
Is There a Difference Between Blueboard and Greenboard?
Green board and normal drywall are inferior to blueboard. To begin with, the blue board is more difficult. The blue board is more durable and difficult to break than the green board. As a consequence, it doesn’t scrape or dent. As a result, it works best in high-traffic areas of the house or business.
Second, a blue board looks far better than a green board. It is simple to paint or plaster. It has a more appealing appearance than ordinary drywall.
When it comes to DIY drywall installation, a blue board is considerably simpler to work with than both green board and standard drywall. Even so, you’ll need the necessary talents to put everything together. Any errors you make throughout the installation process will show up after the project. As a result, having a professional install the blue board is preferable.
Plaster and paint are simple to apply to the blue board. Before applying plaster or paint to regular or green drywall, add a coat of primer.
In comparison to the green board, the blue board is more moisture and mold-resistant. It can be used in the same places as green boards, as well as in areas where there is more water.
Frequently Asked Questions(FAQs), “Is blueboard fire resistant?”
What is the purpose of the blue board?
Blueboard is a type of drywall or plasterboard sheet that is approximately 7.5 mm thick and is used as cladding on the exterior walls of a building. It’s usually nailed or screwed to a wooden or steel frame that offers structural support.
What is the difference between blue board and drywall?
After they’ve been taped and the seams and fasteners have been coated with compound, drywall panels are covered with paper that will accept paint directly. The more absorbent paper layer of Blueboard is intended to connect with a veneer plaster finish before painting.
Is it necessary to depict the blue board?
Because it is neither waterproof nor water-resistant, it must be rendered to accomplish this. Builders like working with it since it is lightweight, easy to install, and requires just plaster and tape on the seams instead of joint compound.
Is the blue board made of gypsum?
The core of the blue board is still gypsum, but the exterior is covered with blue paper, thus the name. This blue paper is made to stick to a certain kind of plaster. This gives contractors much greater control over the texture and smoothness of the walls once they’ve been plastered.
Is blue board resistant to moisture?
The blue face material on the blue board is intended for use with veneer plaster.
It’s not moisture-resistant drywall. Because veneer plaster can only be used with regular drywall if the seams are sealed and a specific primer is employed, blueboard is a speedier and more cost-effective alternative.
Is it okay if I only paint the blueboard?
You won’t be able to hide all of your joints by painting the blueboard. Also, because of the Bluebeard’s dryness, you’ll need many coats since the first two tend to soak into the surface, resulting in color fluctuation and brush lines.
