Holds up well & more importantly no shrinkage

Great for the purpose, chose black for natural effect
Great product, we first tried without applying masking tape on the floorboards and it made a mess. We then taped around the gaps in between floorboards,and applied the product and it turned out neat and clean. We chose black colour, so after the floorboards have been sealed with this product, it still looks natural and if the gap is still there, which is perfect for a natural rustic look. The only one thing I noticed is that it seems to shrink a bit over time, and when fully cured we noticed cracks and gaps here and there. Which we will go over . But overall great product and really recommend!

Great for filling gaps between wooden floors
Great product for filling in gaps you get when a wooden floor becomes a bit loose. Easiest way to apply this is to use masking tape either side, then I took the nozzle off and pumped it onto my finger so that I could get more down into the gap giving it a better finish! Remove masking tape after about an hour, looks amazing! I filled my gaps in black as I am going to stain the floor black, do the gaping before staining.

This stuff is amazing, none of the mess of silicone Highly Recommended
Used this to seal the back of worktop, so much easier to work with than silicon which leaves a film over everything. This wipes off with water when applying and looks great.

Easy to use, easy to smooth, easy to clean up
Bought because it came in black, to caulk a joint between two dark painted pieces of wood. Worked perfectly for the job. Consistency of regular caulk, easy to clean up with a damp cloth. Easy to smooth into the joint. Hasnโt cracked after 2 months use ๐
