The only person that sleeps better than kenny is me. 8 hours minimum for that boy, last night he had a cool 14 without a peep.
But as for the sealants, i have not used that one, consideri g the brand i would assume id does as described,
I have used this stuff reccomended by my tiler on my concrete worktop, travertine floor tiles and patio . Came up almost invisible/matt.
