Opportunistic feeders, their diet varies from one region to another. In the Antarctic, killer whales eat about 67% fishes, 27% marine mammals, and 6% squids. Killer whales in the Bering Sea (near Alaska) eat about 65% fishes, 20% squids, and 15% marine mammals.
Even though your shower grout looks dry, using it too early or sealing it before it's ready may damage it, leading to premature failure. Most cement-based grouts require a cure time of 48 to 72 hours before applying a penetrating sealer.
How long should I wait to seal my grout? My grout package doesn't have very clear directions, actually they are just pictures and after the cleaning process it says 16-24hrs with a picture of some one standing on it. What I am wondering if I have to wait 24hrs to seal or if I should wait the 48 that the sealer I bought says? Any help is much appreciated.
