Hi
I have just read your question. What you are suggesting is quite sensible. It is much cheaper to strip and seal an emulsion dressing rather than sanding and sealing a floor so it is quite logical to explain this to your client on the basis that it is a sacrificial coating. It could be that instead of using an everyday seal which you put down with a mop or laying tool you use a product such as 'Insurance' from Best-Chem which can be spayed or eventually misted on to the floor and buffed in. Over a period of doing this you form a very hard skin which may never, if looked after correctly, need stripped back. It is important, however, to ensure that the wood seal has completely cured before doing either of these things. It is sensible to leave for say 10 days,
Hope this helps.
Regards,
