Yes, you should dampen porous tiles and the joints lightly with a damp sponge before grouting to prevent the dry tile from sucking water out of the grout too quickly, which helps the grout bond and cure properly; however, the joints themselves should remain clean and dry, and you should never wet non-porous tiles like porcelain or glazed ceramic. Always ensure the tile adhesive is fully set and clean all spacers and excess thin-set from the joints first, and avoid soaking the surface, as excessive water can affect application.
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.
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.
If you're grouting porous tiles in temperatures above 25°C, dampen the joints with clean water first. It's not advised to grout in temperatures below 5°C or in damp conditions.
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.
4 of the Most Common Regrouting Mistakes
While grout pens are not a permanent solution to some grout issues, they're still an affordable and easy way to help you transform your home. Just be sure that you choose a grout pen in a color that works for your style, the room itself, and the tile.
Sanded grout is best for tile installation with wider joints 1/8” or more, as the grit creates a stronger bond that's less prone to shrinking or cracking. Unsanded grout works best for narrow grout lines less than 1/8” or with delicate surfaces like polished marble, metal, or glass tiles to prevent scratching.
Tile Gone Wrong: Top Tile Mistakes to Avoid By Chip Wade
Butt joint tile are tiles cut accurately enough to be set with no grout joints, butted up next to one another. This installation produces a unique appearance – textural and monolithic. It is also both labor and cost saving as grouting is a laborious process.
Always apply adhesive horizontally with a notched trowel, rather than in a swirling motion. You should never store tiles in direct sunlight prior to fixing. Tiles should be dry, clean and free from grease, wax, oil, curing compounds, etc.
These are 5 grouting mistakes the pros always notice, and how you can avoid them for a high-end finish
The golden rule for bathroom layouts is zoning for flow and function, creating distinct dry (vanity/storage), semi-wet (toilet/tub transition), and wet (shower/bath) areas to ensure comfortable movement, easy cleaning, and separation from steam, prioritizing clear paths, adequate clearance (e.g., 30 inches in front of fixtures), and making the toilet less visible upon entry.
Regrouting tiles is a straightforward job that most confident DIYers can tackle themselves. Take your time when removing the old grout to avoid chipping or damaging your tiles.
The grout sealer and recolourant, which is a superior alternative to grout paint or a cheap grout pen can save homeowners a lot of money. Old grout can quickly look like new and transform the look of any bathroom, kitchen or any other part of the home where the grout on tiling has started to look 'tired'.
You can hide uneven grout lines in two ways. If the tile has been installed but has no grout yet, choose a grout that's the same color as the tile. If the tile already has grout, change the grout color to closely match the color of the tile.
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.

One of the first signs of a sloppy job is grout lines that don't line up, or messy cuts. These are obvious aesthetic signs that the contractor is cutting corners. Even worse and less obvious are uneven tile surfaces, what's known as lippage.
Light gray grout maintains a clean and fresh appearance while being more forgiving than white when it comes to stains and discoloration. Darker gray shades, such as charcoal, add depth and richness while effectively masking dirt and algae buildup.
Professional tilers usually cover 20–50m² per day. The exact number depends on tile size, layout, prep and adhesive.
Diagonal Floor Tile Layouts
Mary Gordon, the co-founder of InSite Builders & Remodeling, finds a handful of floor tile layouts to read as dated, one of which being the diagonal floor tile layout. "It was once used to make small bathrooms look and feel larger, but diagonal tiles now look dated and busy," she says.
The ideal way to lay your flooring: room and light
As a general rule, make sure to lay your floor in the same direction as the main light source in a room and in the same line as the most frequently used entrance. If there are several doors and windows, then opt for the direction that's the easiest to install.
