No dust. Even using the most up to date equipment which has vacuum systems to eliminate dust when sanding, the environment during the process will not be free of dust. Whilst the majority of the dust created will be vacuumed or wiped away by the machines there will still be dust particles which are not contained. Two consequences of this are:
Some dust particles will still settle on the surface after completion of the job.
A certain amount of dust will filter into other rooms in the house.
Deep cuts or gouges in the timber to be treated (caused by such things as carpet trimming knives etc.) will not be eliminated.
Stains such as urine from pets or water marks in the boards or around nail holes will not be removed.
Gaps between boards (left to counteract expansion or shrinkage) cannot be filled because if the boards do shrink or expand the filler will crack.
If boards have borer damage they will not be as glossy as the boards in good condition.
Putty filled areas will not feel the same as the timber areas after the application of coatings.
Silicone products (which also include fly and hair sprays, fabulon etc.) will react against the polyurethane coatings causing rejection.
A cobweb pattern on coatings can be produced by 12 volt downlights.
We recommend painting skirting boards after completion of the coating job as there may be minor marks where the Edger meets the skirting.
A two tone effect may be produced on the perimeter of some older timbers when stain or Black Japan is used.
Variation in grain and colour may occur between old and new boards.
