Ultimate Pro-Finish Decorators Caulk White 380ml

The HB42 Ultimate Pro-Finish Decorators Caulk fills deeper and wider than most other caulks, designed for a professional finish. The 380ml tube has over double the flexibility of leading caulk brands at 12.5%, making it more resistant to movement and longer-lasting.

It can be used in joints up to 25mm wide and 20mm deep and can be painted over in just 1 hour, forming a durable, flexible seal and contains a fungicide to discourage mould growth. HB42 Pro-finish Caulk is an easily applied, white, solvent-free, acrylic sealant for external and internal use.
