Multi Purpose Fillers

Multi Purpose Fillers are an essential product for any DIY project as they can fill holes, cracks, and gaps on various surfaces. However, it is essential to check the label to determine whether the type of filler you choose is waterproof or not. Once you’ve applied the filler, it’s important to let it dry completely and sand it smooth before painting over it. If not done correctly, the filler can crack or shrink after painting, resulting in a less-than-perfect finish. It’s also crucial to apply the filler correctly and clean the surface before application to prevent cracking. With proper usage, Multi Purpose Fillers are a valuable tool for achieving a flawless finish on your DIY projects. At MB DIY, we offer the most reliable Multi Purpose Fillers, including Decorating Caulk, Gap Filler Foam, Everbuild One Strike Filler, and more!


Everbuild One Strike Filler

Everbuild One Strike Filler is a Multi Purpose Fillers that lives up to its brand name. As a “one strike” filler, it can fill and smooth out gaps, cracks, and holes in just one application. This makes it the ideal DIY product for all your time-sensitive projects.

One Strike Filler can be sanded smooth after drying. This allows for easy surface preparation for painting, wallpapering, or tiling. It can also be used on a variety of surfaces, including wood, plaster, concrete, and brick. However, it’s important to note that One Strike Filler should not be used externally as it is not weatherproof.

Everbuild One Strike Filler dries quickly, typically within 30 minutes, allowing for fast project completion. And when it comes to gap size, One Strike Filler can fill gaps up to 75mm wide, making it perfect for large and small gaps alike.

Decorating Caulk

Decorating Caulk is a type of Filler used in various DIY projects. It’s a flexible sealant that can fill gaps and cracks around windows. It may even be used on doors, skirting boards, and other areas that require a smooth and seamless finish. The application of this filler is simple, thanks to the silicone gun, which ensures precise and easy distribution. The filler is packaged in a convenient tube that makes it ideal for use on surfaces such as skirting boards and door frames.

Decorating Caulk differs from a multi purpose filler in that it remains flexible after drying. This is good for the natural expansion and contraction of the surfaces without cracking or breaking. A filler, on the other hand, is more rigid and is typically used to fill larger gaps and holes.

When it comes to using Decorating Caulk, it’s best to apply it before painting, as it can be painted over once it has dried. This ensures a seamless and professional-looking finish. However, it’s important to note that Decorating Caulk should not be used in areas that will be exposed to water, as it is not waterproof.

A common question when it comes to using Decorating Caulk is whether it’s better to use caulk or silicone. While both products can fill gaps and cracks, silicone is best suited for areas that require a waterproof seal. Decorating Caulk is more suitable for areas that require a flexible sealant that can expand and contract with the surface.

Gap Filler Foam

Gap Filler Foam is a specialized Multi Purpose Filler that’s perfect for filling large gaps, particularly when installing windows. During installation, there’s often a significant gap between the window frame and the brickwork, and that’s where Gap Filler Foam comes in. Its expanding properties make filling even the largest gaps quick and easy.

When used for window installation, Gap Filler Foam is typically applied as the primary filler before applying silicone sealant for a professional-looking finish. This not only fills the gap but also creates a secure and watertight seal, protecting windows from moisture and drafts.

However, it’s essential to use Gap Filler Foam with caution, as it cannot be sanded or painted over, making it unsuitable for visible areas. It’s best suited for use in hidden areas where appearance won’t matter. Gap Filler Foam can fill gaps up to three inches wide, making it perfect for larger gaps and spaces. Additionally, it’s waterproof and creates a sturdy and durable seal once cured, ensuring longevity in any environment.
