Applying the Poultice (final solution)
1)Clean the stained area with cold water & stone soap. Remember to bolt rather than wipe.
2)Prewet the stained area with a little water. Prewetting fills the pores of stone with water; so isolating the stain & accelerating the removal by the chemicals.
3)Prepare the poultice. If a powder is to be used, premix the powder & chemicals of choice into a thick paste. If a paper poultice is to be used, soak the paper into chemical. Lift the paper out of the chemical until it stops dripping.
4)Apply this paste only on the effected area & make a layer of about ¼ inch thick.
5)Allow the paste to sit for 12-24 hours after covering it with plastic sheet. Drying may take more time.
6)Remove poultice from the stain, rinse with distilled water & dry with clean rag.
7)If stain is not removed completely then repeat the same procedure again.
