So I repainted my topsides of my 18 foot skiff (23" X 18' per side) using the roll and tip method after a very mediocre attempt with a 3" Purdey brush. I failed to achieve an even coat of paint due my lack of understanding of the method and sheer inexperience. I applied too much paint on the roller and thus the foam brush was unable to even out the application. I had summoned all my collected data and painting wisdom gleaned from any book or forumite and still did not like the results...
So I spent some effort to get some more specific instructions on the finer points of rolling and tipping...a method that is supposedly so good that you read things like, "it looked like it was a spray job"... etc.
I have decided that general descriptions for us inexperienced in a process are sometimes just not enough. Decent success can be subject to the quality of the instructions on the method, and many times little details are left out.
Here is what I have formulated as a recipe for success using this method and having tried it out now... and having been very happy with the results.
1) Use 1/2 of the standard 7" foam roller pad on a 3" roller frame.
2) Use a 12" X 12" piece of plywood as a flat roller pan...for instilling paint onto the roller pad...this allows great control of how much paint actually is on the roller pad. (I fabricated a small table with a hanging spot for my roller frame and a hole for the foam brush haandle and a spot for a paint container).
3) mix up about 8 ounces of paint in a small container and only pour out enough at a time to charge the roller pad maybe a couple of times at most.
4) Thin the paint appropriately (I found this was only found out by doing... and getting a feel for what consistency seemed to work well) and continue to add thinner as you go along as the thinner in the paint container is evaporating.
5) With a controlled amount of thinned paint on the roller pad, roll a swath about 4-6 inches wide up and down on the topsides and then tip from left to right with a 3" foam brush.
6) Pour a little more paint on the ply sheet, load the roller and roll another swath next to the first...and again tip with the foam brush...dry to wet blending the 2nd swath to the first. Tip lightly and evenly and be sure you did not roll on too much paint.
7) Keep moving and repeating the above steps and you get really great results even in 85-90 degrees.
The above allowed the application of a very uniform thin coat of paint that pretty much shows no marks... and looked great.
I have boiled down the process more or less to the above elements and have found the results very satisfying. I would suppose that many of those more experienced in this process could offer some additional tips that would expand the possibilities of this process and of course allow for covering larger surfaces with just as good results... I would welcome any such tips as I am quite impressed with the smoothness and uniformity of the layer of paint I have been able to apply with this method.
By the way, I noticed that the minute you put too much paint in the roller pad, the paint roller pad applied too much paint on the work surface which in turn made it very difficulty to avoid some sagging (slight runs) in the cross brush marks. Even If you tried to tip the paint, you would get some drooping/slight runs from your strokes with the foam brush. I decided the way to master this process was to experiment with thicker paint to optimize coverage, most likely paint and Penetro.
Maybe it just takes me awhile to get some things, but I am happy that I finally figured it out, heat and all. I just failed to really understand the nuances of the process when looking at the basic method in an overview description. Some of my mistakes were having way too much paint on the roller, using too wide of a roller pad, thinning the paint too much...just to mention a few.
