WeatherPrufe WOOD VARNISH: A siliconised-alkyd based exterior grade coating designed to offer maximum protection in a harsh climate.
The spreading rate is dependant on the hardness of the timber to which it is applied.
As a general rule, a spread rate of 12 square metres per litre will be obtained on hard woods and on previously coated substrates.
On soft woods, the first application can have a spreading rate as low as 6 square metres per litre.
Sand down uncoated surfaces using a good quality sand paper.
Dust off well and apply the first coat thinned 10% with mineral turpentine.
Apply two further unthinned coats at 24 hr intervals, sanding lightly with a fine sand paper and dusting off between coats.
Previously varnished surfaces should be sanded down to an even matt finish and rendered dust free before applying two coats unthinned at 24 hr intervals.
Sand with a fine grit sand paper and dust off between coats.
