A pool vacuum works by using the suction from your pool pump. Once the vacuum is connected to the pump, usually through a connection in your pool's skimmer (a separate compartâ¦ment next to your pool), debris is pulled through the vacuum hose to the filter where it is removed from the water.
In most cases, you should allow the grout to dry overnight before using that room as total dry time may take up to 24 hours. If you are thinking about sealing your grout after you have installed it, you need to wait even longer than that so that all of the moisture has had time to be released. In most cases, this process can take as long as 72 hours to complete. Different grout mixes from different manufacturers can have their own instructions for dry times. To ensure that you always allow ample time, consult the instructions on your specific packaging and follow any directions for application to the letter.
When it is not dry, tile adhesive can ooze up into a good grout job and discolor it. You may also encounter tiles that are somewhat loose because they haven't had time to dry completely. This can ruin a great grout job. Most tile jobs take two to four days before they are completely dried.
