Some brush in compounds can weather off over time – seek advice from the manufacturer. Careful pressure washing can work. Do not hold the nozzle too close to the surface of the slate.
The issue with brush in compounds is that they are non porous. No sealer can penetrate the surface of the slate whilst they remain.
They need removing before any attempt to seal is made, regardless of the type or brand of sealer being used.
Floorseal Stone Floor Cleaner will remove light contaminations of brush in compounds. It will also remove dirt, grime and cement/grout haze residues.
Soaking with water with long dwell times can help. If it is just a residue careful pressure washing may work. Do not hold the nozzle too close to the surface of the slate.
Slate is a non acid sensitive stone so an acid wash can be used to remove cement. You could use Floorseal Cement & Grout Haze Remover Adjust the dilution rate to suit the level of residue on site.

Yes it will deepen colour so will create a wet look finish but without a high shine. It does not totally replicate the effect of wetting slate with water – no product is capable of doing this in exactly the same way.
It is critical that the slate and substrate is dry and the conditions remain dry during curing.
We would recommend waiting until the substrates has had chance to dry out. It is not always the case that the slate will display efflorescence after laying but it is always possible. Its worth allowing a window of time for this to occur – 6 weeks is often enough.
