Review: Great product. Recommend! - This filler is amazing. It's so easy to work with and now I've found it, I won't be buying any other brand. Easy to apply, to smooth over, no sanding necessary. Dries quickly. Highly recommended 👌🏽
Review: Smooth finish, Problem with container. - Good product, but seal at bottom split and stared to pour out both ends. I folded over and used gaffer tape to hold together. Likely to be a one off? I bought to fill old raw plug holes. All other filling use tub stuff.

## Questions & Answers

**Q: Can someone let me know if this is suitable to fill a gap (due to movement) of laminate flooring? Thanks**
A: I don't honestly know I have only used on plaster walls etc.Product dries white so would show white on floor I would expect unless you can colour it with woodstain.

**Q: What colour is this?**
A: The colour is off white.

**Q: can you paint over this?**
A: Yes, I have done.

**Q: Would one tube cover all around a window frame usually?**
A: It depends, of course, on how big your window frame is and how big are the gaps. Although this is described as a flexible filler I would take s look at other products specifically made for the type of job you have in mind.

### ⭐⭐⭐⭐ Smooth finish, Problem with container.
*by K***B on 6 November 2025*

Good product, but seal at bottom split and stared to pour out both ends. I folded over and used gaffer tape to hold together. Likely to be a one off? I bought to fill old raw plug holes. All other filling use tub stuff.

### ⭐⭐⭐⭐⭐ Quality brand
*by M***N on 7 April 2025*

To seal is a quality male and this filler is no exception. Easy to use straight out of the tube, dries quickly to a smooth finish and doesn’t crack. Good for filling smallish cracks and holes in plaster.
