I must admit that when the client specified Farrow & Ball for exterior work, I was slightly dubious of the product. I knew the interior eggshell is fine and a nice drop of paint, but knew little of the exterior eggshell. I have always opted for the mainstream trade paints for exterior work.
The client had already purchased the Farrow & Ball, so it was decision made really. They left the primer/undercoat to my discretion. I chose good old Zinsser Coverstain, tinted to the top coat, as its the perfect bridge coat for water based top coats over previously painted oil-based topcoats.
The garage doors were in reasonable condition so all that was needed was a degrease and a flattening with 180 grade sand paper. Then cleaned off with methylated spirit. Then came the Coverstain with a little helping of Owatrol oil. Not only is this rust inhibiting, it aids flow out and improves levelling.
Then came the top coats, like I said I had never tried this before so I gave it a stir and watched for the reaction of it falling off the stir stick. My thoughts were that it was reasonably thin, which is a feature I like in water based paint. I grabbed the Zamix latex extender just in case of lap marks. Zamix is a product that I had been using since last April, but thats for another time…
A drop into the Farrow & Ball top coats and off I went. I am a believer in the the right paint brush for the right paint when it comes to water based paints, but since I knew nothing of this paint, I used the Proform contractor, a brush that I know I can rely on with thin water based paint.
To say I was impressed would be an understatement. The paint applies so easily, nice and thin needing minimal effort, with excellent flow out, and it keeps a wet edge for a good while. It levels like I have never seen for an exterior water based paint. The pictures are of close-ups of the door lock and a panel of the actual door, just to give you an idea of the finish that is achievable with this product.
After talking to my colleague Ron Taylor who is also a Traditional Painter and kitchen painter in Warwick about this product, I found out that there is a handful of decorators using the very same product on interior projects. I can see why, and for interior eggshell trim work I see no reason not to specify it.
If you have any questions about the products I used, please ask, I am happy to help.
