No, you should remove grout haze first, then let the grout cure completely (often 72 hours to 10 days), and then apply a sealer; sealing before haze removal can trap residue or react poorly with acidic haze removers, making cleanup harder and potentially damaging unsealed grout or porous tiles. Always clean the haze with water/pH-neutral cleaners (or specialized removers for epoxy grout), rinse thoroughly, let it dry, and then seal the grout and tile.
In your bucket or basin, mix equal parts warm water and white vinegar. This concoction is like magic when it comes to breaking down that grout haze. The vinegar's acidity will help dissolve the haze, and the warm water will make it more effective.
Ideally, the final wipe-down will take place after the grout has been allowed to cure for 24 hours. However, grout haze could still potentially be removed within a few days.
His opinion is that grout needs to breathe. If you seal your grout and water somehow does get behind or under tiles, it's stuck there. It has no way out. Sealing grout can lead to sealing in moisture which can lead to bigger problems.
They should be maintained with a sealer to help protect the tile's surface. Not every type of grout needs to be sealed either. Epoxy grout is non-porous, doesn't need to be sealed, and is applied on hard non-porous surfaces. Epoxy grout helps protect against stains and water.
You generally should not grout directly over old grout for longevity and adhesion, as it often leads to cracking and peeling; instead, you must first remove a significant portion (at least 2mm) of the old grout, thoroughly clean the area, and then apply the new grout to ensure proper bonding and a lasting finish. Special rejuvenation grouts or epoxy grouts might require less removal, but scraping out most of the old material is the best practice for standard grout.
Avoid these 9 common grouting mistakes that could be ruining your tiling projects
The 1/3 rule for tile is a layout technique for long rectangular tiles (like wood-look planks) that recommends staggering joints by one-third of the tile's length, not the traditional 50%, to minimize lippage (uneven tile edges) caused by natural tile bowing, creating a smoother, safer, and more visually harmonious floor or wall. Instead of a standard brick-like pattern, it creates a diagonal or "stair-step" grout line, which looks more natural and helps hide slight height variations between tiles, making the surface feel flatter and more professional, especially under raking light.

Fortunately, it's not a permanent smudge, and can be readily removed with the right know-how and knowledge. So, if your tiles have been impacted by this annoying problem, here's exactly what you need to know about removing grout haze.
Grout haze occurs when a thin layer of grout residue remains on the tile surface after installation. This haze often results from waiting too long before wiping off the grout. When water evaporates, it leaves behind minerals and cement particles, forming a dull or cloudy film.
Combine four parts of water and one part white vinegar to use on porcelain or ceramics. Use a delicate cloth dipped in the vinegar mixture and wipe the tiles with it. If necessary, add more vinegar to make the mix stronger. To eliminate any residual vinegar, wash the tiles with normal water once the rubbing is done.
Once the grout has hardened, the tiles will be left with a slight haze on them. Clean it up by going over the area lightly with a damp cloth, then buff immediately with a dry cloth.
The 3-4-5 rule for laying tile is a method to ensure a perfect 90-degree (square) corner, based on the Pythagorean theorem (32+42=523 squared plus 4 squared equals 5 squared32+42=52). You measure 3 units (e.g., feet, inches) along one wall/line from the corner, 4 units along the adjacent wall/line, and the diagonal distance between those two marks should then be exactly 5 units, confirming a perfect square corner for your tile layout. This prevents tiles from running crooked and ensures straight grout lines.
Bleach, ammonia, and cleaners with these harsh chemicals added in can cause grout to yellow, fade, or become discolored. They can also degrade the grout and cause it to erode over time.
If you are wondering how long you should wait between grout sealing on your high-traffic floors or frequently-used showers, the answer is at least once per year. However, The Grout Medic recommends sealing those areas every six months.

The process is exactly the same: First, mix some baking soda with water to form a paste (a ratio of three parts water to one part baking soda is usually recommended), then apply this to the grout and rinse it away after it has had time to work its magic.
The occasional use of vinegar on porcelain or ceramic tile with cement-based grout should not cause damage. However, frequent or regular use can discolor and weaken grout and should not be used for routine maintenance.
