Hi,
Was wondering if anyone wants to chime in on the relative merits of sealants vs. costs.  I have been using Aldon's SBS sealer as my tried and true impregnating color-enhancing sealer for slate floors and the price is $41.00 per gallon including shipping (shipping free). I see that the color enhancing solvent based sealer from Stone care central is $66.39 plus shipping. 
On the non- color enhancing side, the water based impregnating sealer for stone care central is $31.00 and the same day water based non-color enhancing sealer from Aldon is $44.00.  the solvent based color enhancing variety from stone care central (which i have tried and like) is $98.00 and the comparable Aldon fine stone sealer at $92.00/gallon including shipping.  It appears that the non-color enhancing solvent based stuff is pretty expensive but the water based stuff is pretty cheap.  So, I guess my questions are 1. Is a solvent based non-color enhancing sealant worth twice the cost as water based? and 2. How do the stone care central products compare to Aldon's (or any others for that matter)? 
Thanks,
Baird
