Staff Education - How well does your staff understand the differences between sealers? Consider holding a training session on this topic. Some questions your staff should be able to answer include

What are differences between a topical sealer and an impregnator? What are the advantages vs. disadvantages?
How much sealer or impregnator do I need to complete the project?
Is a single application sufficient or are multiple applications required?
Will the product application change the appearance of the stone?
How is natural china marble maintained after treating?
What factors should be considered prior to product selection? Is it necessary?
Will sealing protect the china granite from etching?
Consumer Education – When discussing the pros and cons of sealers and/or impregnators with your consumers, advise the consumer to:

Carefully review the ‘factors to be considered’ prior to treating (checklist from page 1).
Read the Manufacturers Warranty and Instructions.
Contact the Manufacturer prior to application if you are unsure or need clarification. The wood-working analogy of ‘measure twice, cut once’ applies.
Consider the life span of the application (1-year, 2-years, 5-years, etc) – keep a log of each application with maintenance logs.
Don’t switch from one product to another without fully understanding any potential issues. Not all product are alike – again, consult with the Manufacturers.
Consult with your Stone Professional as necessary
Ask, does the stone need to be treated in the first place?
MIA Recommends:

1.  Careful review of multiple factors (i.e. type of stone, its finish, its location, and how it will be maintained) be taken into consideration when determining how to protect the stone.

2.  If the choice has been made to protect the stone with a sealer or impregnator, always consult with the Manufacturer/Distributor to advise and choose the appropriate sealing product.
