Wet and dry sandpaper

[Spyro]

Do you use it wet to begin with and finish of dry or just use it wet and wash off? (painting topsides)

 

[snowleopard]

Wet only, then rinse thoroughly.

A dash of washing up liquid in your water helps. Don't forget that in this weather you can use hot water in your bucket. /forums/images/graemlins/cool.gif

Soap effectively makes the grade higher. for instance when preparing top quality car paintwork 1200 grade followed by 1200 with soap bar rubbed onto the paper gives a super smooth surface for a paint like cellulose which will sink into imperfections

Try to use a sanding block at all times, using your fingers will only result in a wavy finish.

 

[Lakesailor]

Good point. 3M do a very good rubber block with built in pins to hold the paper.

 

[Grajan]

The loss of skin from wet fingertips when rubbing down without a block happens remarkably quickly and if large areas are involved and you have wrapped W/D around a block of wood wear rubber gloves!!

Thanks for all the tips guys, I have found out the hard way about loss of skin from finger tips /forums/images/graemlins/frown.gif

A techie at International paints advised 1200 grade with Coal Tar soap for burnishing 2 pot poly.

 

[Lakesailor]

I'm pleased to be able to confirm that he is correct.

Not often I can concurr with those who know!

Wet all the way, add a bit of fairy liquid to the water too.

Re: Wet and soapy

I reckon you've set a record by Lakesailoring everyone on the thread.

As Defined by tcm

""lakesailor"is transitive verb. It neeeds a subject, and an object. The subject "lakesailors" the object. The object is "lakesailored" eg "i've been lakesailored". You "lakesailor" someone when you provide essentially the same (correct) answer to someone else, but (importantly) some time after that answering post - cos you didn't read all the answers.

Being "completely" lakesailored happens when the original questioner thanks the second responder, not the first."

Re: Wet and soapy

Using fine wet or dry dry clogs it up in arund 15 seconds, after which you are just rubbing paint residue over the paint - scrubbing at it can warm it enough to soften the surface and to tear the original paint film - giving you a whole lot more work to flat it off again!
