My last 2 exterior painting jobs i've had a problem with the my touch up's not matching the same color that was painted the day before. It seems like the color is drying a little lighter & really sticks out. This is my first year doing a lot of exterior painting & I've never had a problem up until now. The weather is colder now & I'm done painting out side for the year but I'm wondering if the cold causes the paint to dry a differnt color or what. It seems weird that it's never happened & then it happened 2 jobs in a row

I have noticed darker colors can have more of a problem with that. Are you spraying and then touching up with a brush? Can you roll or feather it out with a brush?? Good luck!

Ya, I spray & then touch up with a brush. I tried feathering the touch up's in with a brush but it still sticks out.

I think the pigment lays down different when its sprayed as opposed to brush/roll. Thats part of the reason it might be a good idea to backroll over a spray..it touches up better.

Can you go back and re-spray the areas?

The last exterior I sprayed there were a few spots that needed touch up. I thought hitting the spots lightly with the sprayer would be the best plan, since that was the original appication method and you can feather easily with spray.

To my suprise you could clearly see the spots that I touched up with the sprayer . I went back with brush and lighty feathered it out with the brush almost dry toward the edges of the spot I needed to fix. It blended very nice and you cant tell at all.

This might not be much of a help to you, but want I'm saying is I've always had the best luck touching up with a brush. I use very minumal paint on the brush and feather it out very carefully.

If you have 10 gallons of the same color paint 5 gallons were from 1 Sherwin Williams & 5 from another. Should the colors still match up. I know Roofing shingles have to be bought from the same batch otherwise the color will be slightly different

My experience has been "probably not". We have run into that with different stores. We have even had problems with a 5 and 3 ones if we don't mix them all together.

I am anything BUT a painter... so this may be totally off the mark.

First the spraying o VS brushing to fix problem sounds right on to me. I have had some minor experience with this with interior doors.

Another thought to ponder: Even in the same dye lot or when mixed by the same guy at the paint store colors will vary if ever so very slightly. I do not remember where I picked up the following idea, but it might be someting to consider.

Bracketing:

When you are painting use up 2/3 of the first container of paint and then mix in 1/3 + of the next container into the first, keep doing this as you go. This will help to blend the slight color variations.

When you get to the final container blend it all with the last one as best you can. Keep this for touch ups.

Instead of bracketing, we call it "boxing" your paint together. We usually get two or three clean 5 gallon buckets and mix it all at once filling each bucket half and half. We put our strainers into each of the mixing buckets and strain it clean as we mix it.
