Description
TIMCO Acrylic White Caulk 300ml
TIMCO Acrylic White Caulk is a paintable general purpose filler and sealant for internal gaps and cracks. It adheres to most substrates and can be painted over with most paint types or papered over. It is a strong choice for decorating and finishing work where a smooth, neat seal is needed. TIMCO describes it as ideal for internal gaps around plasterwork, decorative mouldings, skirting boards, and architraves.
Key Features
This acrylic caulk is fast drying, flexible, and easy to tool. It also has an anti-slump formula, low odour, and water-resistant performance for normal internal use. Some merchant specifications list it as paintable in around 2 hours with a skin formation time of about 7 minutes. As a result, it is a practical option for quick decorating jobs and finishing work.
Applications
Use it for sealing and filling internal gaps between plasterwork, skirting boards, architraves, decorative mouldings, plasterboard, painted surfaces, PVC, and PVCu trim details. Therefore, it works well for both trade and DIY decorating jobs where a paintable finish matters. TIMCO states it is for internal gaps and cracks, and merchant specs also list typical substrates including wood, plasterboard, plaster, paint, PVCu, wallpaper, and decorative mouldings.
Paintable White Finish
The white finish suits most interior decorating work and can be overpainted or papered over once dry. That makes it a good option where standard silicone would not be suitable because paint will not adhere properly. In many cases, acrylic caulk gives a cleaner finished result around trims and joints before decorating.
Pack Size Options
This product is available as a single 300ml tube or box quantity. TIMCO lists the cartridge as 300ml, code 732871, with a minimum order quantity of 12, so a trade box option is a good fit for larger jobs.
