Applying the Poultice
Once the stain is identified, please follow the steps shown below.
- Wet the stained area with distilled water. Pre-wetting fills the pores of the stone with water - isolating the stain and accelerating the removal by the chemical.
- Prepare the poultice. If powder is to be used, pre-mix the powder and the chemical of choice into a thick paste.
If a paper poultice is to be used - soak the paper in the chemical. Lift the paper out of the chemical and allow it to drain until it stops dripping.
- Apply the poultice to the stain - being careful not to spill any on the non stained areas. Apply approximately 3mm thick overlapping the stain area by about 10mm all round.
- Cover the poultice with a plastic film. Tape the plastic down to seal the edges.
Allow the poultice to dry thoroughly. The drying of the poultice is what draws the stain from the stone into the poultice material. If the poultice is not allowed to dry, the stain may not be removed effectively. Drying should normally take from 24 to 48 hours.
Remove the poultice from the stain. Rinse with distilled water and buff dry with a soft cloth. If the stain is not removed, apply the poultice again. It may take several applications for difficult stains.
Be aware that some chemicals may etch marble surfaces. If this occurs, apply polishing powder and buff with a piece of burlap to restore the shine.
NOTE: If the problem is serious in nature or too large in size, please consult a professional cleaning contractor or your stone supplier.
