### ⭐⭐⭐⭐⭐ Perfect Gap Fill 👌
*by A***. on 10 January 2026*

### ⭐⭐⭐⭐ Alternative of loctite
*by L***T on 21 December 2025*

Nice product

### ⭐⭐⭐⭐⭐ Useful DIY
*by D***D on 10 May 2025*

Applied it on plastered wall and door frame. Plastic surface won't hold the adhesive. My door frame was completely damaged due to moisture. Sprayed this product on complete frame and hence the dirt on nozzle that is seen in the picture. The fully cured product feels like thermocol. Lesson learnt: Allow the product to dry 100%. It should feel like rock to touch, only then slice (and not pull) the excess from outer edges. If the cervix is deep, then it takes about 30 to 40 mins to dry. The nozzle can be cleaned once the foam dry to touch as this product doesn't stick to plastic. A little goes a long way. No need to spray until we see the peak of foam coming out of the cervix as the nature of this product is slow expansion. Wear gloves during application else taking the product off the skin is a nightmare. I wish the nozzle was much slimmer.
