scotchgard and wool question

[sweendogg]

I can understand the use of solvent carried protectors on water-sensitive upholstery since you obviously don't want to add water.

I'm trying to understand how using an OMS carrier can make the same fluorochemical better than if it was carried by water.

It certainly makes it a boatload more expensive to use.

Brian the only thing I could potential see as a positive is that the oms based is not goint to be absorbed as easily as the water. So you get an appropriate curing time.


Just my .o2 cents!

Carpet protector bonds to wool fibres better when in acid state than alkaline state.

process

pre-spray
acid rinse[do not rake yet]

put equipment away

apply carpet protector[rake in now and set pile]

collect money

done

Using that logic, why would you post spray with acid?
The water based ScotchGuard and Teflon are on the acid side anyhow.

If the above process is carried out,there is no need to post spray with an acid.
The acid rinse used will neutralize and remove detergent residue from the pre-spray
stopping any cross contamination and allowing the sg or teflon to cure.
