To add to what @woodchucker wrote, if the lapping plate has been charged with abrasive grit, it will wear any tool you use on it.Was advertised as a surface plate but I have used my granite one for lapping in the past. In either case it will serve my purpose for layout fine, and for $50 I'm happy....

If it is new and unused (uncharged) then I suppose you could reasonably use it as a surface plate. Or, you could have it reground/scraped to remove any embedded grit.
All this assumes it is in fact flat enough for your purposes.
On the other hand, maybe you have a few layout tools that could stand a bit of lapping.
