To come back to floors, our factory was criticized in a customer audit for its stained floors. So it was coated in a nice grey epoxy, which looked marvelous, one problem you could not walk on it if contaminated with oil water anything, so you had to develop a very strange way of walking. After much research it was decided to use the stuff London Undergrouned used which left a finish like emery paper very non slip great err no! if paper was dropped and trod on it would not shift unless you attacked it with a floor cleaner with wire wheels floor now looks really c**p. On the third go and many pounds later a compromise was found still hard to walk on but if you did slip it was not as far. I adopted what we used to use which until sombody decided they looked untidy, and that is duck boards, c**p falls through and depending on the height of the board the sweeping period can be greatly extended. We are never going to please her indoors unless we learn to hover, mine swears I walk around with my eyes shut. Just develop the contrite look and carry on as normal. I see it as keeping them gainfully occupied until the next soap is on. The last line is in jest please don't take offence. I'm not brave enough to say it out load even if you can avoid retribution during daylight you have to sleep sometime. I must be doing something right as we have been married for 49 years, or I did something wrong in passed life and this is punishment.
