"Kevin and his father did excellent work on my house! I couldn’t be more satisfied. They were punctual and very professional. Despite it raining, he was still able to come and get the work done in the time frame given. Besides doing the requested job, they were more than happy to help me with a few minor jobs here and there. They even went ahead and painted some areas that could use touch ups that weren’t included in the job. I’ll definitely use them again for any future projects and will recommend them to friends and family."
Back to the article. You can add water to all latex based paints / thinner to oil based paint. The tinting base has absolutely nothing to do with it. Say you are working outside and throughout the day you have to add a little water to keep the same consistency. If somebody really tried to add 20% to 50% water they no longer would be painting they'd be performing a whitewash or pickle finish.
