Particularly in the case of tiles and stone, the most important clean this surface ever receives is its very first: the handover / construction / builder’s clean.
Get this right and your floor is off to a great start: looking great and performing as it should.
Get it wrong and you’ll see all sorts of issues both short and long-term.
Grout residues can sometimes produce an obvious haze across the surface which is unsightly. But it’s not always the case that you can see the residues. You might have a dirty floor which then gets cleaned and looks good, but the micropores of the surface could still be harbouring grout – it’s just that you cannot immediately see it.
These residues cause two main issues:
1) They will act as a magnet for contamination to “stick” to the surface
2) They will compromise the slip resistance of the floor
An added worry is that the contamination which builds up will further worsen the slip resistance.
Many surfaces are recommended to be sealed after cleaning and before handover; not doing an effective clean before sealing means that the residues will be trapped within the floor.
So how do you know if you’ve done this most important of cleans correctly?
- Don’t rely on generalist products – you can’t necessarily even rely on specialist products: the method of application is just as important as the product used.
- Don’t rely on generalist cleaning contractors – conduct scientific testing to assess the effectiveness of the deep clean: a pendulum test will tell you if the floor is achieving the slip resistance it should (compare the on-site results with the out of the box measurements in the catalogue); swab testing is a great indicator of any contamination still in/on the floor.
