moss on shakes

[WaveWacker]

Going to pressure wash then stain my cedar shakes on the house. There is a little bit of "moss" growing on them and was wondering if there is anything that is made that will help inhibit future growth.

Thanks!

A treatment with a moss killer. Directions will say if that goes on before or after your power wash. Some siding and deck washes might have that killer in them already.

Then an additive to the stain.

if you use a good penetrating sealer you shoulnt have a proplem, if you are staining your shakes look into sikkens cetol- trust me you wont regret, then every couple year run over it with a pressure washer. I dont know if its sold around here but at my house in fl, I mixed algecide/ with my wood sealer- it prevents stuff from growing on wood. just guessing but your probably having this problem under trees, or the shady side of your house? sometimes if the woods always wet it seems to attract growth more than other area of the structure. good luck

I have read that stips of galvanized material or something with magnesium in it stops the mold growth. There are strips that you put under the top edge and that will prevent it from happening. You should be able to find it at United Products or maybe a big box.

The galvanized strips work good.

The "strips" you guys are talking about are actually zinc, you can find them at any roofing supplier
