Lithofin slate sealer - Tile Advice

[what]

Can you apply the above with a fiber based roller as opposed to a foam roller. The pdf instructions recommend foam roller which I have used in the past but not with complete success, as the the sponge structure reacted and expanded causing the roller to rotate in an upredictable manner. However at the moment I only have a fiber roller to hand to complete the job tomorrow - will this do? The problems i can speculate upon (and this is pure conjecture) is that the fiber roller compounds "could" partially disintergrate due to a chemical reaction releasing the fibers into the finish or that it may absorb too much sealer which may cause a problem.
So has anybody used a fiber roller to apply this stuff and got a way with it?

Don't tend to use fibre ones because of leaving bits behind, I've use fine mohair and the pads nowadays
