Lithofin Stain Stop MN

[IHB]

How long after treatment would you recommend waiting until I grout? Stone is polished Marble & not particularly absorbent.

 

[One Day]

Polished marble is best buffed dry (if any remains on surface) after about 15mins in my experience - ready for grouting then.
If you want an even quicker product try Universeal Rapid All-in-one.
