The house was painted last summer by Ron. Two weeks it took for the job to be completed. The exterior was washed with warm water and a mild detergent. The pores in the walls were sealed with putty. The exterior was painted after the putty dried. Latex paint was used since it is easy to apply and cleans up with water. Satisfaction is what was felt once the job was done.
