How to Apply Stucco Over Wood Siding
- 1). Attach a metal lath as a base. Cover the wood siding with roofing felt, nailed in place with roofing nails. On top of this, add a layer of metal netting, also attached with nails.
- 2). Mix the stucco in a wheelbarrow or barrel. Follow the instructions on the pre-mixed stucco package to determine how much water to add, then stir thoroughly.
- 3). Apply a scratch coat to give the stucco something to adhere to. Use your trowel to apply a thin 1/4-inch coat of to the entire surface.
- 4). Wait one hour, then use the plasterer's rake to comb through the scratch coat to a depth of 1/8 inch. Give this coat at least 24 hours to dry after you complete the scratch coat.
- 5). Apply the final coat. Use the trowel to apply another 1/4-inch coat on top of the scratch coat. Vary the pressure and angle of your trowel to give the surface texture.
- 6). Mist the surface periodically with water during the next few days. Stucco that is allowed to cure slowly and with added moisture will be least likely to warp or crack.
