Question
We have a semitransparent terracota stain over the cedar that mildew keeps showing even though the house is exposed to the sun, we had the house pressure cleaned and they washed off some of the stain and got to close to the house, I would now like to paint the home a solid paint, what preparation is required first and what type of paints are best for cedar siding? Thank you.
Answer
Sonya,
The first thing you need to do is address the mildew issue. Washing it off does not kill it, it only removes the visible result of the existence of the fungus. You need to apply a mildecide to kill the fungus. The surfaces need to be thoroughly clean and dry before applying a new finish.
The type of paint to be applied depends on what is on the house now. If you don't remove all of the existing stain it will dictate what can be applied now. The existing stain can be a water based, oil based or alkyd (synthetic resin based). These products are not all compatible. You need to know what is on the house now and stick with that type.
You can go to any good paint store and tell them what is on the house now, what cedar product (smooth, rough sawn, etc.) is the siding and they can recommend a mildecide and an appropriate paint. The paint selected is less dependent on the species than on what is on the house now. Good luck.
