Tiling is a wet, abrasive, alkaline operation and it generates the single most damaging residue on a building site: cement slurry. On a finished floor it etches, it bonds and it is almost impossible to remove once it has set. Protecting a floor during tiling is largely about managing that slurry rather than about protecting against tools.
What grout haze is
Grout leaves a thin cement film on everything it touches, including the tile surface and whatever is protecting the floor around it. Wet, it wipes off. Left to dry, it becomes a hard film that needs acid to remove – and acid is exactly what cannot go near stone, marble or some metals. So the rule on a tiling job is that the slurry comes off the same day, without exception.
Cutting produces the worst of it
Wet cutting tile and stone produces a fine abrasive slurry in quantity, and it travels. Cutting outside the room is the answer, and where that is impossible, the cutting area needs its own cover that is washed or replaced daily rather than the good cover that protects the finished floor. Mixing the two is how a clean cover ends up behaving like sandpaper.
Buckets, sponges and where the water goes
A tiling operation uses a lot of water and it ends up somewhere. A bucket set on a finished floor leaves a ring; a sponge rinsed over it leaves slurry. The working area needs an impermeable cover with a turned-up edge, and the rinse water needs a container rather than the floor. Both are obvious and both are routinely skipped on a tight programme.
Point loads from tile stacks
Tile is heavy and it gets stacked. A stack of boxes on a finished floor is a standing load on a small footprint, which is exactly the case that dents timber and vinyl and can crack a tile. Stacks go on a load-spreading panel, and stacks go down flat rather than on a corner – a tile box corner is a very effective punch.
Where the floor is being tiled anyway
If the floor in the room is the one being tiled, there is nothing to protect and the question is only about the surrounding areas and the route. That is usually a small cover job, and it is worth specifying it that way rather than covering the whole floor plate.
Grout colour and the light grout problem
A light-coloured grout shows every mark and it is the specification that generates the most handover complaints. On a light grout, the cover comes up and the floor gets cleaned in the same operation, not a day apart, and any slurry that has set gets dealt with immediately. Dark grout is far more forgiving and worth recommending where the client has not fixed on a colour.
Adhesive buckets and the ring they leave
A bucket of tile adhesive set down on a finished floor leaves a ring of residue and, on a porous surface, a stain that outlasts the job. Adhesive and grout mixing happens somewhere; make sure that somewhere is on a cover, and that the bucket is not set down on the floor when it is moved. It is the most common avoidable mark on a tiling job.
A rigid PP honeycomb panel under a tile stack spreads the load; corrugated PP sheet will not and should not be used for it. The impermeable turned-up cover is a separate item for the wet area.
What we can do
We supply impermeable PP protection with a turned-up edge for wet work and rigid honeycomb panels to spread tile stack loads. Tell us what is being tiled and what the surrounding floor is, and we will size the order to the working area rather than to the room. Wet trade sequencing is covered in wet trades and protection that does not go soggy.
