Cement grout is the familiar cement-based material placed between tiles. Its color and width shape the pattern of every joint, while its texture affects cleaning and future repair. It fills ordinary tile joints, but it does not replace the waterproof layer or the flexible seal needed where corners and different materials move.
Use it for ordinary tile joints, not every gap
Cement grout is a practical first choice for many wall and floor joints when cost, color, cleaning, and future spot repair all matter.
- Ordinary bathroom-wall and kitchen-wall tile joints
- Entry and balcony floors where joint width and drainage can be reviewed together
- Projects that can test grout color against the real tile and plan for later spot repairs
Do not use grout to hide failed waterproofing or standing water, and do not fill moving corners or fixture edges with a hard material alone.
- The work is trying to solve missing waterproofing or poor drainage with grout
- The gap is at a wall-to-floor corner, bath, basin, window, or meeting point between different materials
- Strong stain, mold, or chemical resistance is being promised without evidence for the exact product
A question from INBOT
Check joint width and tile surface before color
Two grout products with the same color name can contain particles of different sizes and allow different amounts of time for filling and cleaning. Test the chosen product on the actual tile.
- Does the product suit the actual joint width?
- Measure the width and depth, then compare them with the product's stated range. Products with coarser or finer particles suit different widths and may leave different marks on a soft or polished tile surface.
- Could it scratch or stain this tile?
- Test polished stone, soft glaze, and heavily textured tile in a small area. Check for scratches, color staining, and residue that remains after cleaning, then view the dry grout under the room's lighting.
- When should it be cleaned and used?
- Follow the stated water amount, how long the mixed grout stays workable, and the first and final cleaning times. The earliest time for walking, wet cleaning, or shower use also varies by product.
- Where is a flexible seal needed instead?
- Wall-to-floor corners, bath and basin edges, and places where different materials meet can move. Mark these separately and use a flexible seal designed to absorb that movement.

These examples come from official manufacturer pages. Cement grout differs by allowed joint width, tile surface, wall or floor use, and indoor or outdoor exposure. Choose more than a color: match the actual joint width and review cleaning and hardening instructions.

A question from INBOT
Separate hard grout from flexible joints in the quote
Tile grout included does not identify the product, color, working method, cleanup, or the gaps that must remain flexible.
- Record the tile product and surface, joint width and depth, grout manufacturer, product, and color.
- State whether the chosen grout contains coarse or fine particles and keep the tile-surface test result with the approval.
- Set the water amount, how much area will be filled at once, cleaning times and tools, and who removes leftover residue.
- Mark flexible seals at corners, drains, and places where different materials meet separately from hard grout.
- Put the earliest walking, wet-cleaning, and shower-use times in the schedule and protect the surface while it sets.

A question from INBOT
Read a stain and a recurring crack differently
Surface staining may be a cleaning issue, but a crack returning in the same place can point to movement beneath the tile.
- Avoid heavy wet cleaning before the grout has set, and remove everyday spills promptly with a cleaner approved for the product.
- Test any method for water marks or discoloration on a small area before using a strong acidic cleaner across the whole floor or wall.
- If a joint repeatedly cracks or falls out, investigate its width, movement below the tile, and whether a flexible seal is missing before filling it again.
