View Full Version : Spunking Up Letters

Giving letters a little spunk is fun. Not only is it easy and fun but makes for a special looking sign. Here are the steps. The photo's below are of a panel done by my good friend Mark Yearwood. This is an old sign about twenty years and still looking like new. The letters are bright and shiny because they have aluminum leaf surfaces. This is a inexpensive material that's available to everyone. This sign wouldn't be nearly as attractive without the extra bling.

Leafing with aluminum is similar to regular gold gilding except its cheap and can be purchased at most hobby and craft stores. It comes in 5”X5” packs and is several times thicker gold leaf. Not too fussy to work with. This material is a substitute for silver and works better all round because it doesn't tarnish.

If you're interested in giving this a try you'll need to purchase some regular gilding varnish known as “Gold Size” Check your local sign supply and go with what they have on hand. After brushing a nice even coat of the size you 'll need let it stand for several hours until it becomes tacky. Aluminum doesn't require as an exact tack as does gold but it shouldn't be liquidy. That is to say you want it to feel like it's setting up. After applying your aluminum you can smooth it down with a soft brush. I use a mop. A woman's facial brush is perfect. Watch out if you get caught. Then you're on your on.

The other technique that makes for a “Spunky” look is the use of either a Brad Point Round Over or a 110 degree V bit to surface the top of the letters. That will give them increased viability. I'll post on that later. Please not how much brighter the chamferred letters appear. It's all in the router bit and the aluminum.

Joe, I have a few questions:

1) What is the sign constructed from? It LOOKS like machined aluminum. If it isn't then it is all the more impressive.

2) Is the aluminum leafing applied to only "Matt Wilson"? Or is it also applied to the diagram of the building also?

3) I've never done anything with gold or aluminum leafing, but find it very attractive of course. But when one reads of how the leafing is attached to the base, with thin, seemingly weak sizing, how is it that it stays attached when exposed to the weather? One would imagine that the leafing would need to be encapsulated with a coating to keep it from falling off with failure of the sizing. But if one were to coat the leafing for protection against the elements, then it would loose its brilliance. So how do you keep the leafing attached, without messing it up with a top coating of some kind? Or is it simply possible that the leafing forms such a super covering of the sized base, that no further protection from the elements is required??????

Thanks, Chuck

Chuck,

All good questions and glad to assist.

Gilding has been done for centuries and it's a fool proof method of attaching thin leafs of gold, silver, aluminum, copper and varrigated leaf. I saw first hand when visiting Egypt a few years ago. This technique is a good one.

The "size" if a form of slow drying varnish. It's different from other varnishes in that it dries from the bottom first leaving a tacky surface. Once the leaf is applied it's good for years as seen by the aged sign I've posted.

This sign is HDU which is an excellent surface for this process. There's no reason to topcoat aluminum leaf however I've been top coating my gold due to wind born sand and lawn sprinklers takes it's tole. I use automotive clear and it doesn't degrade the brilliance very much. Makes for a tough, durable letter too.

There's no substitute for doing your own testing. While you can read and listen to us senior sign artists you'll need to actually get your hands dirty to see the wonderful effects for your self. Well, I guess there's one substitute and that's to attend a workshop.

Thank you Joe for your clear reply. I do have a follow up experiment for gilding, but my computer with my camera software is messed up! So I will follow up later. Thanks again, Chuck
