These are just a few photos and descriptions of failed floors that I have come across.
Finishing with lacquer or oil can spoil if not applied correctly spoil a perfectly installed or re-finished floors.
British Standards and manufacturers instructions clearly state that there should be sufficient application of adhesive either in the join or when fully bonding to a sub-floor.
Preparing a sub-floor is a vital part of an installation. I often see de-laminated soothing compound or screed that have not had the latance removed. This is a common cause of failures.
Very often a smoothing compound is not applied correctly. There are number of reasons for this to many to comment on.
All to often I come across patterns that have not been fitted in a straight line. Installers often blame manufacturers but a considerable number that I have inspected have been due to a lack of experience and knowledge of the installer and sometimes trying to just roll out the carpet without using standard equipment to aid alignment. Time constrains are often used an a reason!
Pile reversal and pile pressure are confusing. Both are the result of the pile moving in a different direction (pile reversal) or flattening (pile pressure) causing light to reflect off the surface at different angles. The result is an unsightly appearance. Some can be recovered.
