JML Flooring’s recommended preparation for sanding and finishing
If building, renovating or decorating, schedule the start date in relation to other trade processes. This is essential.
Carpentry, electrical, plastering, plumbing and glazing needs to be completed before work is commenced.
Any silicone based products which comes into contact with the floor before the finish is completed will cause rejection. These deposits are often brought in by various trades people on the footwear.
Ensure that normal electrical and water supplies are accessible at the premises for the floor sanders. Without these the tradesmen are unable to operate.
All floor coverings, furniture, fixtures and fittings from the floor to at least head height should be removed as well as tacks and staples. However, the more empty the premises the better.
All painting except for the final coat on the skirting boards should be completed. However careful the tradesman may be, there may be a need to “touch up” the paint work afterwards in the event of minor “scuffing” marks.
Protective dust sheets are recommended to cover any items that may accumulate dust and which could not be removed.
Gas and electrical appliances are to be disconnected in the direct vicinity of the sanding area.
The area needs to be adequately lit with the appropriate power.
Clear and safe access to the site.
The fumes and wet areas are good reasons for the occupants to vacate the premises, both during the operation and the drying period. Book accommodation in advance and be flexible, just in case uncontrollable factors cause a delay in the process.
Extra tips in preparation for commercial and domestic customers
Seal any access areas such as vents, fireplaces and windows that will allow dust to enter the room. Masking tape and paper should be adequate.
Cover light fittings to prevent dust gathering on them.
Fold curtains into plastic garbage bags and seal them at the top.
What to expect
Some markings on the skirting boards from contact with the Edger and/or Polyurethane
Some variation in the colour and grain between old and new boards.
Stain around the perimeter of some older timber may produce a two tone effect on the floor.
Please note that solvent based polyurethane coatings are toxic when wet and therefore all foodstuffs, fabric, leather and other `porous’ materials must be removed from close proximity of floors being sanded and polished. All the vapours are to be ventilated and aired before returning to live in the house. Approx. 24 – 48 hours.
What not to expect
A completely dust free environment.
Modern sanding machinery is fitted with dust collecting equipment and sanders will endeavour to clean dust away by vacuuming and wiping down surfaces. It is virtually impossible however to totally eliminate dust from the job which has a couple of consequences: There will always be some dust particles that settle on the newly finished surface. There will be an amount of dust through the rest of the house.
Removal of deep cuts such as those from carpet trimming knives or deep gouges in the boards.
Removal of stains from within the boards and around nail holes such as animal urine and water marks.
Filling gaps between the boards. These gaps are not filled because subsequent shrinkage and expansion in the timber will cause cracking in the filler.
Do not expect boards damaged by borer to have the same gloss level as those in good condition.
Do not expect areas filled with putty to have the same feel as the timber after application of coatings.
When the tradesmen leave
Most coatings dry within 24 hours, but they will take anything up to 14 days to fully harden.
As a guideline you can walk on the floor after 24 hours in stocking feet. Avoid shoes or “fluffy” socks that deposit textile fibres on the floor.
Because the floor coating needs to cure or harden for about 14 days, only replace light furnishings and avoid scraping on the floor surface.
Heavy items can be replaced later, ensuring that they are not dragged.
Rugs can leave a backing pattern mark on the floor, so replace them after 2 weeks if possible.
Re application of coats and sanding will depend on the amount of wear attributable to the floor. (Approx 3 – 4 Years).
