Hello,

 

I need to paint these foot wells / floor. I have read all the instructions available. Some of the surface is still perfect, was no rust underneath paint. I need to minimize the amount of sandblasting I have to do. I have cleaned everything before grinding / sanding with aqua klean.  Sanded / wire wheeled surfaces. Now I am about to sand blast the rusty areas. I was hoping not to put any water on the previously rusted / sand blasted areas.

Please see photo attached, please note sanding is not 100% finished I will sand off all remaining paint from low points etc. 

 

Questions are really:

1., Can I Aquaklean/ rust blast the shiny steal, only sandblast rusty areas and rustseal it all, or would it be more beneficial to aquaklean /rust blast / water wipe blasted areas as well?

2., Blasting media will be ordinary sandpit sand ( friend left many bags with me from moving) It may be beach sand, is the possible salt content a problem? 

3., Instructions suggest 320grit sanding, paint shop suggested rougher surface for best adhesion,  I am happy to go as low as 100-150 grit as long as it provides a better base?

Thank you    

 

 

HI,

The sandblasting does not seem to be working out very well, as you can see it on the photo. Done a short test run along, where I point with my fingers. The clean metal gets an excellent finish, but the rust does not clean out properly. I guess I have to clean up the whole lot and do the rust blaster acid treatment everywhere, otherwise the rust does not get stabilized, correct? Your advise would be much appreciated. Thanks!

As long as the sand blast material was fresh (not recycled) and the surface has been kept clean, please go straight to the RustSeal step for those areas.

 

2. Blasting media will be ordinary sandpit sand ( friend left many bags with me from moving) It may be beach sand, is the possible salt content a problem?

No. Blow off the sand blast residue with fresh clean air. That is all you have to do.

 

3. Instructions suggest 320grit sanding, paint shop suggested rougher surface for best adhesion,  I am happy to go as low as 100-150 grit as long as it provides a better base?

Yes, 100-150 grit is perfectly fine. That will provide a great surface profile for paint adhesion.

 

Please let us know if that helps and if you have any additional questions.

Yes, go ahead and do the RustBlast to etch that surface and create an ideal surface profile for the adhesion of RustSeal. Rinse with water and then dry immediately to minimize any flash rust created from the humidity in the air.
