Decorators Caulk
Imperfections in your skirting board, wooden tables or plastering? Decorator’s caulk is essential for the final stages of many DIY projects, helping to fix gaps and ensure a seamless end paint job.
Decorators caulk is an essential product for achieving a clean, professional finish when decorating. It’s ideal for sealing small gaps and fine cracks between skirting boards, door frames, window frames, and walls. This permanently flexible acrylic filler is easy to apply and helps create a smooth finish that blends seamlessly with surrounding surfaces.
Typically used during the final preparation stages of decorating, decorators caulk can be painted over once dry – just make sure to check the drying time recommended by the paint manufacturer. It’s especially useful for areas where slight movement may occur, thanks to its flexible seal properties.
It can be easily painted over with most paint types or covered with wallpaper, and there is no sanding down required as it has excellent slump resistance.
Whether you're a professional decorator or tackling a DIY decorating job, caulk helps to fill cracks in plaster, concrete, and wood surfaces with ease. Apply it using a caulking gun, then smooth it over with a putty knife or finger for a neat, tidy line.
