Most homeowners see only the start and the end of a granite installation: slabs arriving on a truck and, a few days later, a shining floor. What happens in between decides whether that floor will stay level, sound solid underfoot and hide its joints for decades. This article explains the granite installation process step by step, as we follow it on residential and commercial sites, so you know what to expect and what to check.
Step 1: Site inspection and readiness
Before any slab is cut, we inspect the site. Granite should be fixed after plastering, conduit work and plumbing lines are complete, and before the final coat of paint. We check:
- Whether the base slab is clean, sound and free of loose material.
- Whether walls are reasonably square, as this affects how cuts fall at the edges.
- Door frame positions and the height at which shutters will clear the finished floor.
- Bathroom, kitchen and balcony areas where slopes are required.
If something is not ready, it is better to wait a few days than to fix granite and break it out later.
Step 2: Marking the finished floor level
A level line is marked on the walls throughout the area, usually one metre above the intended finished floor. Every room, passage and doorway is measured from this same line, so the whole floor finishes at one height and there are no steps at thresholds. Where slopes are needed, the fall is marked from this reference too.
Step 3: Checking and sorting slabs
Every slab is inspected when it arrives. We look for cracks, chipped edges, thickness variation and colour differences. Slabs are then sorted by shade and pattern. Good-looking slabs are reserved for the most visible areas, such as the main hall and entrance, while slabs with minor marks are used where furniture or cupboards will cover them.
Step 4: Dry layout
Slabs are laid loosely on the floor without mortar to plan the final arrangement. This step is often skipped by hurried fixers, and it shows. During the dry layout we:
- Balance colour and pattern across the room.
- Decide the starting line, usually from the main doorway or the centre of the room.
- Place full slabs in visible areas and push cuts to walls.
- Mark border and band positions as per the drawing.
- Number the slabs so they go back in the same order.
Step 5: Cutting and edge work
Granite is cut with diamond blades on cutting machines. Wet cutting keeps the blade cool and reduces dust. Cuts around door frames, pillars and pipes are marked carefully and cut slowly to avoid chipping. Edge work such as rounding, half bullnose, moulding, miter cutting for corners and grooving for stairs is done at this stage, before fixing.
Step 6: Bedding and fixing
Granite is most commonly fixed on a cement and sand mortar bed, with cement slurry or adhesive applied to the back of each slab for full bond. On flat, accurate bases or for wall work, adhesive fixing alone may be used.
The fixing sequence
- Spread the bed to the required thickness for that area.
- Place the slab gently and tap it down with a rubber mallet.
- Check with a spirit level and straight edge across the slab and against its neighbours.
- Lift and add or remove bed if the slab rocks or sounds hollow.
- Maintain even, tight joints using spacers where needed.
The aim is zero lippage, meaning no slab edge sits higher than the next. On factory-polished granite, lippage is very visible because light catches the raised edge.
Step 7: Joint filling
Once the bed has set, joints are cleaned out and filled. We use epoxy or Tenax-type joint fillers, tinted to match the granite, so joints blend into the stone. The filling is pressed in fully, then the excess is scraped off before it hardens. Cement grout is sometimes used in outdoor and rough-finish areas, but for polished interior floors, a resin filler gives a much cleaner result.
Step 8: Edge polishing and corrections
Since granite is factory-polished, the full floor does not usually need grinding. The visible cut edges, nosing, cut-outs and any joints with small level differences are ground and polished on site using polishing machines and progressively finer abrasives until they match the surrounding surface.
Step 9: Curing and protection
The bed needs time to cure. During this period, heavy loads and construction traffic should be kept off the floor. If other trades are still working, the granite is covered with protective sheets or cardboard to avoid scratches from ladders, paint drips and dragged materials.
Step 10: Cleaning and handover
Finally, cement residue, epoxy smears and dust are cleaned off using suitable cleaners, never strong acids that can damage joints and some granites. We walk the client through the floor, tap-check slabs for hollowness and explain basic care.
How to check a finished granite installation
- Walk the floor and tap slabs with a coin. A dull, solid sound is good; a hollow one is not.
- Look along the floor at a low angle with a light source. Raised edges will show.
- Check that joints are straight, even and fully filled.
- Pour a little water in bathrooms and balconies to see it run to the drain.
- Inspect edges and nosing for consistent polish.
