The 10 Best Resources For Installations

Varnishing Wooden Floors

It is possible to re-varnish a previously varnished floor which is good condition, however, if the previous varnish has started to wear in some areas, its flaking or cracking, the only good option is to peel the original varnish and start again.

Any other finishing on the floor need to be removed prior varnishing so that the timber is freed from all the dirt, polish, and oil. When all the old finish has been eliminated, the floorboards will now be sanded and if required, stained.

Varnishing Steps
Doing Options The Right Way

First Coat of Varnish
When the first coat of the varnish is applied, it is thinned using the suitable thinner, typically one of between 25 to 50% . This layer acts as a bond between the timber and the subsequent coats of varnish. Thinned varnish is typically water-like making it easy to work with but also easy to splash about.
Installations – Getting Started & Next Steps

Use a 10 cm brush to apply the thinned varnish along the length of the floorboards and not across the grain. Complete the length of a couple of floorboards before you can move on to the next ones. As much as possible try to avoid spreading onto the edge of the next floorboard since any overlapping may be visible when the job is done.

How to Apply the Remaining Varnish Coats
For these coats use the 10cm brush to apply the varnish first across the grain and then brush it along the grain. When the varnish starts to set in, avoid using the brush to go back over it so as to avoid leaving the brush marks. First work on the length of a couple floorboards before you can finally move to the next ones. Try to avoid spreading the varnish to the adjacent boards as overlapping will show in the final job.

Give Time for the Varnish to Cure
Do not rush to start using the floor, the varnish manufacturer gives a recommended time for leaving it before moving in furniture. Often, the time given for varnish cure is 72 hours which is quite different from the dry for overcoat time which is the time given for the varnish to dry to take the next coat but it is still not ready to be used. The longer one can wait before using the varnished room the better.

A floor that is in reasonable condition, re-varnishing can be done without fully stripping the original coat of finish. Re-varnishing this type of floor can not be compared as to when the old finishing has been peeled off and the surface sanded and re-varnished; any damage on the original surface may remain visible.
