What is decorators caulking used for?

Decorators caulk is used to fill small gaps and joints before painting, such as the line between skirting boards and walls, around architraves and mouldings. It leaves a flexible, paintable finish, which is what sets it apart from general-purpose sealant.

Can you paint straight onto decorators caulk?

Decorators caulk is designed to take paint once it has cured. Check the product's drying time before overcoating and let the caulk cure fully first, so you avoid cracking or peeling.

At what stage do you use decorators caulk?

Use decorators caulk at the finishing stage, after fixing trim and filling larger defects but before painting. It closes the small movement gaps around skirting, architraves and window trim so the surface reads as one clean finish under the paint.

Should I caulk between skirting and wall?

Yes, filling the gap between skirting and wall is a common use for decorators caulk. It closes the small movement gap and gives a neat, paintable line, which is why skirting board caulk is a standard part of interior finishing.

Learn more about decorators caulk

Decorators caulk is a flexible, paintable filler used to close small movement gaps and neaten joints before painting. It differs from general-purpose sealant because it's made to take an overcoat cleanly, so the finish looks like one continuous surface rather than a visible bead.

Most interior decorating work uses acrylic decorators caulk. It's easy to apply, flexes with normal timber movement and paints well once cured.

Typical uses

Filling gaps between skirting boards and walls.
Sealing around architraves, decorative mouldings and other timber trim.
Closing narrow gaps around window trim and door liners where a paintable finish is needed.
Touching up cracked plaster.

How to choose the right decorators caulk

Choose acrylic decorators caulk for most interior decorating jobs where you want a paintable finish and straightforward application.
Pick interior sealant caulk for internal finishing and exterior sealant caulk for weather-exposed gaps, rather than using one product everywhere.

Before you order

Confirm whether you need a cartridge product for a gun or a ready-mixed option for smaller decorating tasks.
Allow for the size of the room, the number of joints and expected wastage when working out how much to buy.
Check drying time and when the caulk can be painted.
Make sure you have the right application tools and cleanup products for a neat finish and easy site work.
