10 Best Decorators Caulks 2025 in the UK

The EVO-STIK Decorators Caulk is a versatile option for those tackling low-movement cracks and gaps in interior spaces. It's made of acrylic, which is known for its flexibility, making it ideal for areas like windows, door frames, and skirting boards where some movement may occur. This caulk excels in its quick drying time, allowing it to be overpainted in just one hour, a feature that can greatly speed up decorating projects. Its white color blends well with most decor, and the product can be sanded for a smooth finish once fully cured within 24 hours.

One of the main advantages is its ease of application, a critical factor for DIY enthusiasts and professionals alike. The caulk is solvent-free and designed for interior use, providing results that can last up to 15 years, making it a reliable long-term solution. However, this particular product lacks specific mention of water resistance, which might limit its use in high-moisture areas like bathrooms or kitchens.

Its flexibility is suitable for low-movement areas, but it might not perform as well in places with significant structural shifts. Additionally, the 380ml size may be sufficient for small to medium projects but could require multiple purchases for larger jobs. This caulk is particularly well-suited for interior decorators dealing with cosmetic repairs and enhancements.

The UniBond Indoor Window & Door Frame Sealant is a white acrylic sealant designed for a variety of indoor sealing tasks around the home. It is versatile and adheres well to most building materials, making it suitable for skirting boards, dado rails, coving, worktops, and wooden rails. One of its strengths is its flexibility, which helps maintain the seal over time despite slight movements in the structure.

It is also mould resistant, adding to its durability and making it a good choice for areas prone to dampness, though it is not suitable for bathrooms or other wet areas. Paintability from one hour after application allows for quick finishing, and its water-based formula means it’s easier to clean up than silicone-based alternatives. However, it needs a full 24 hours to cure completely.

A significant drawback is its limitation to indoor use only; it’s not suitable for exterior applications or uPVC windows. Also, its water resistance is not sufficient for high-moisture areas like bathrooms. With a 5-year guarantee when applied correctly, it provides some assurance of lasting quality. This product is ideal for homeowners looking for an easy-to-use, reliable, and paintable sealant for general indoor use.

The Polycell Trade Decorators Caulk White Cartridge is a versatile product, particularly suited for window surfaces. Each cartridge contains 380 millilitres of white acrylic paste, making it a good option for filling gaps and cracks. The material type is acrylic, known for its good adhesion and flexibility, which is beneficial for areas prone to movement. Flexibility is a crucial feature here as it helps the caulk to adapt to small movements without breaking.

The caulk has a high rating of 4.6 out of 5 stars from 184 reviews, indicating that most users find it satisfactory for their needs. It is also ranked 32nd in Silicone Caulk on Amazon, suggesting it is quite popular in its category. It is paintable, allowing for a seamless finish with the rest of your decor. Water resistance is usually a key factor here, especially for window applications, and acrylic caulks generally offer decent water resistance.

The ease of application is usually straightforward with a caulking gun, especially as it comes in a standard cartridge form. This product is a solid choice for general indoor caulking around windows and other similar tasks where flexibility and paintability are important.
