The need to neutralise floors
With the trend towards more aggressive strongly alkaline strippers comes the problem of high levels of alkalinity left in the floor to create reduced adhesion and reduced life from the sealers being applied.
Other problems that can be blamed on alkalinity are inter-coat hazing and powdering of sealers all leading to reduced life and increased costs associated with the floor maintenance.
Ideally stone floors (terrazzo, marble, exfoliated granite as well as concrete floors) should have a pH around 8.5 - 9 maximum. Normally you will find that the cement matrix on terrazzo will normally be above 10.5 and when alkaline strippers are used this can climb to 11+.
NEUTRO is the answer
By applying NEUTRO to the floor after stripping with an alkaline stripper you remove a great deal of the risk associated with alkaline floors. Polish or sealers not bonding, hazing between coats and even powdering can be prevented if coatings are laid correctly.
Use on ceramics, terracotta and resilient sheet or tile floors. Don't just limit the use of NEUTRO to stone floors or after stripping. Restoration and deep stain removal on hard baked vitrified or ceramic tiles with PUNCH can easily be neutralised when followed with a NEUTRO rinse to ensure that sticky alkaline residues don't create high levels of re-soiling on the freshly cleaned surface.
Removal of efflorescence and light rust marks
Vitrified tiles, terracotta tiles laid on external or water affected areas can turn white when alkaline salts leach and deposit on the surface or in the grouting. Rust or brown mineral staining can also occur.
NEUTRO has a multi-purpose use
If there is only a light deposit, NEUTRO can be used to restore the original colour without affecting the glaze or original surface appearance. If heavy deposits are in evidence, use the more aggressive Research Products DESCALER as directed.
NEUTRO Features
- Increases adhesion of sealers to the floor
- Helps prevent powdering and inter-coat hazing of sealers
- Penetrates deep inside the floor matrix quickly (1-2 minutes), other neutralisers require up to 10 minutes activation time
