Today I revisited\na property to take some equilibrium relative humidity readings in a hygrobox\nwhich I installed last week. The property is a new build which had floor screeds\nlaid late last year. The clients are installing expensive oak flooring\nthroughout and wanted to check the floors were dry prior to laying. I undertake\nthese tests often for many flooring contractors and floor retailers across Yorkshire\nas no-body wants the responsibility of laying expensive floor coverings on\nfloors\/ screeds which aren\u2019t dry. The client and contractor had been using the general\nrule of thumb for screed drying of 1mm per day, therefore envisaged it should easily\nbe dry by now. <\/p>\n\n\n\n

This particular\nscreed is Anhydrite (calcium sulphate) and is around 60mm in depth incorporating\nunder floor heating which has been on low shortly after it\u2019s placing. Although\nthe screed has been laid almost three months now, the conditions in the hygrobox\nwere in excess of 90% ERH at 15 degrees. When the hygrobox was removed moisture\nwas also present where the box was installed. Irrespective of the time the\nscreed has been laid, the duration it takes for the screed to dry revolves around\nthe atmospheric conditions. These figures of 1mm per day are judged on idyllic\ndrying conditions at 20 degrees with low humidity levels. In a new build scenario\nhowever, this is rarely achievable as plastering, painting and other building practices\nundertaken after the screed has been laid all add more water to the atmosphere delaying\ndrying further. <\/p>\n\n\n\n

The answer is\nsimple, before you consider laying expensive floor coverings always engage the\nservices of a specialist to examine and check the floors moisture content. A\nfew pounds spent in an assessment prior can save thousands of pound worth of\nreplacement after. <\/p>\n\n\n\n
