The forum upgrade is complete. It was very uneventful. Please post issues in this thread.

Due to a high level of "bad actor" traffic on the community site Jaysen is implementing a forced verification to confirm that you are a human. This is a PITA and he hates it too. The 3.2 seconds it takes for the one time you have to do it every couple hours is much preferable to the hours we are losing to morons clogging the CPU on the servers. Jaysen is still looking to solve this a bit less intrusively and without cost to BBC. Hopefully the magic solution will appear out of thin air soon. Jaysen is already annoyed.

some coloring inconsistencies

Post by DB Michel »

Hello,

I have applied a second coat of Sterling top coat today but I still have some coloring inconsistencies, every where where I applied new paint with the roller there is a difference in color then the previous spot I painted.

Does anyone knows how I can prevent this ?

I tried to take a picture but you don't see it, to much reflection.


Thanks

Do you mean difference between two paint cans or from the same?

From the same can, but the difference in color is where I start with the roller . so every time I load the roller I put some new paint (2inch) on the previous paint that is brushed and after brushing the new load it remains different at the starting point.

I hope you understand , it's a bit difficult explaining .

Sterling takes several days to fully cure. The colors will probably even out over time.

I haven't used Sterling, but based on my other painting experiences I'd think it is flashing off too quickly- is there an additive recommended that would give more working time?

Different animal, but with lacquers you sometimes need to go to a slower evaporating thinner to get the right finish. :?:

I see the manufacturer says reduce 10% to 33% (another souce said up to 35%) for brush/roll application, don't think I'd try more reducer . . . is the weather there hot? Very dry? They say it works best between 21 and 29 degrees. I don't see an Awlgrip retarder offered for roll/brush application, the T0031 should be slow enough. Working by yourself not to roll more than 6 sq. feet(~1/2 sq. meter) before tipping with brush . . .

I have painted Sterling on 3 different boats.
Especially if you are using a color other than white, you may be seeing the primer on the first coat.
Be patient, it will be evenly colored by the third or fourth coat :)

Yes, that maybe it.
It takes many coats to have a deep constant color. Nothing wrong, it doesn't take much paint per coat. I remember Joel painting the FS12 prototype with it and it took 4 coats before the color became uniform.
4 coats but less than a quart of paint total.
