Cleaning old cedar siding

Hi all,

This is my first post other than an introduction (I’ve been reading a LOT in this forum- y’all are awesome!).

A few questions below; I appreciate all the info I can get before tackling the job.

The setup:
32-year-old cedar siding on a residence, north of Atlanta GA. Planning to strip & refinish the whole thing in fall.

The last protective coat was Flood’s CWF in about 1999.

The south side has taken a real beating from the sun, very gray (like an old wooden dock you’d see in the Gulf of Mexico, just blasted by UV).

The other sides are in good to great condition, but very dark on the north—almost looks like stained walnut, it’s so dark on the north side. The owner’s goal is to even out the appearance all around, as close to new, fresh-stained cedar as is practical.

Of course I’ll do a few test patches & wait for them to dry, and observe the results, re-test etc. but info from the experts is always reassuring. :)

1. Is it time to replace the siding on the south side?

2. How well will Gemini Coatings’ Safe-Strip cling to a vertical surface when the stuff is not cut? Injectable Safe-Strip | Gemini Coatings

3. If it should be cut with water, what ratio is a good starting point?

4. I’m thinking the wood is so delicate (hey, it’s old cedar) I should not scrub; there’s very little old CWF left on it. Let the chemicals do the work to avoid “fuzzing†as much as possible. Low pressure washer or just a garden hose & nozzle for the rinse?

5. In your experience(s), will Wood Brightener make a significant difference? Wood Brightener for Cedar & Redwood | Gemini Coatings

Thank you all very much!

This sounds pretty much like a straight forward restoration job. The exposed side is at the end of its life and the darkened sides, well it happens when it doesn't get the sun so much.

I can't comment on the product you referred to as I am not familiar - we have a wood restoration line that we have used exclusively for 7 years (call me).

Plan to strip the entire house - weaker mix on the south side. Actually a weak mix will probably work on 11 year old CWF anywhere.

Absolutely low pressure - cedar will fuzz up if you spit on it. Is this smooth cedar siding or rough cut?

After using a stripping product you definitely will need to use a neutralizer, which will brighten the wood simultaneously. Just by reading the title of the last product you mentioned - I don't know because Cedar and Redwood have completely opposite reactions to the "usual" brightener? For one product to be applicable to both - I'd have to read more before commenting further.

Good luck - and pictures would be fabulous!
