Perfect water sealant with no leaks on cracked items
I had an outdoor water fountain that I forgot had water in it and it froze.... Which made the whole fixture crack at the water expanded. I use this flex paint to see if it would be able to seal the cracks and hold the water and it did!!! No more leaks and i the adhesion holds really really well. Drives fairly quickly like maybe 24 hours. The smell is a little strong so I would let it sit outside as it dries.

Excelente !!
Excelente producto, hace todo lo que promete. Solo lo puedes usar una vez, lo deje muy bien tapado como venía en el instructivo y se seco, pero cumple perfectamente su función.

半分は固まり
トップライトの雨漏りに、ガラス周りをこのペーストでシーリングしました。効果は高いけど購入の半分は固まりで使えない
