Wood Floor....Rough To The Touch

Not too long ago I had an email from a lady who had recently Sanded & Refinished a Wooden Floor at her home....She had put a fair bit of detail into the email about the processes she had employed in her DIY Floor Sanding attempt.

The room was her lounge, and the material of the floor in question was original pine floorboards which had been hidden under carpets for many years. She had used hire shop floor sanding machinery and had been shown [briefly] how to use the equipment. The room was approx 15m2 in size and the Sanding part of the project took her 2 days. The hire machinery consisted of a Main Sanding Machine and an Edger machine.

She had stopped sanding the floor at the 60 grit stage as in her own words she said 'the floor didn't feel too bad' the Edging had been completed to the 40 grit level, and she didn't sand right into the corners as she didn't know how to...The area had been Vacuumed twice before the lacquer was applied.
 

Two coats of a good quality water based Lacquer [Bona Resident] were applied with a paint pad, and the floor was not 'cut back' after the first coat of lacquer had been applied.....The lady was not too happy with the overall finish and asked what i thought the reason for the rough finish/appearance might be.


First of all i have to say that the level of equipment she had used would in my opinion be nowhere near good enough to achieve a professional quality standard of finish, also as a minimum the floor should of been sanded to a 120 grit with the HT7 sanding machine that was used, and the Edging should of been done to 80 grit as a minimum. The corners should of course of been properly sanded and then the whole floor should of been buffed to a smooth 120 grit level with a quality buffing machine such as the Bona Buffer. 


In short I feel that there had been no-where near enough preparation work done before the coats of lacquer had been applied, when a floor is sanded using coarse grit levels, the grain of the wood is opened [widely] and the subsequent passes with the intermediate and fine sandpapers will help to close the grain back up, the process with the buffing machine then helps complete the job....In this case the grain of the wood had not been sufficiently closed before the lacquer was applied, hence the grain 'popping' heavily leaving the material feeling rough to the touch and visually looking poor as well.


I would say that without question the Lacquer had nothing whatsoever to do with the floor ending up feeling and looking rather poor, if the correct amount of preparation work would have been carried out the overall finish would likely of been a lot better......But if you want a professional quality finish....Use a Professional


As i say to alot of clients both prospective and actual....' its all in the prep '
