Latex Over Varnish

katoman

Hi all. Need some help here. We have existing stairs finished with either varnish or varathane. Need to paint the risers and stringers only with a latex.

My painter wants to use an oil base primer. Customer will not allow this due to fumes. So I need to know what primer to use over the varnish.

Painter will of course sand, ready for the primer.

Thanks in advance, Kato.

Dear Sir, I am sorrry i am a new one! I just learn from you.

You can use a paint deglosser then you can use a Kilz 123 waterbase primer/sealer if you like.

KIlz would be absolutly the LAST primer to use, it is crap.
Use any bonding primer such as BM Fresh Start,Zinnser's bullseye 123, etc

You did notice this painting advise about the Kilz came from a plumber, that should tell you something.

I was told a long time ago that; "shellac sticks to anything, and everything sticks to shellac". So I would use Bin primer (it's shellac). I'm willing to bet there are exceptions, but I think it would work in your situation.

GregC

Sorry, My bad, if you see I did put "123" I forgot to type the word bullseye. ..And yes this came from a plumber/pipe fitter & general contractor for over 30 yrs. I think I know a few things about painting and ..hmm..lets see, can I hang wall paper? Thats a tough one.
Tell me Chris can you fit or weld pipe? I doubt it, so stick to the tough job of paper hanging. .. oh BTW Chris, there is a spell checker here

sand to remove gloss...wipe clean...prime with ICI Gripper ...let the primer dry aleast 8 hrs...top coat with premium latex..good to go

try the odorless oil primer you'll get high but wont know what hit you

Frankawitz

Well if the customer doesn't want your painter to use oil base products cause of the smell I would not guaranty the latex will hold up long term, I would use Lacquer thinner wipe down the risers then use the deglosser then use a oil undercoater then your Latex, But I still would tell your customer that they could see the paint fail over time. Good luck.

GregC

Frankawitz, This is a very good advise. Try to convince your customer that the correct way should last longer. Pay now or pay later.

Thanks for all the replys.

Talked to my painter today. He says he'll sand it down real good and use the shelac based primer. Should be ok.

Customer will not allow oil. I agree it would be the best, but it's her house.

Just wait till the customer gets a good whiff of the Bin, the oil based primer would be perfume compared to that.

NormW

Yeah, Bin stinks to high heaven, don't use your prize brush either. Buy a sacrifice brush, or gallons of denatured alcohol.

now for some reason i like the smell of shelac

SW bonding primer would work fine in latex over scuffed surface. It sticks to glass!

alanbj

I should of told you before to use stix(58$ per gal) but i forgot.
I tried it last year it does not come off anything in fact I still have some on my elbow. it smells odd and its pricey but it amazed me how well it stuck to pvc. oh and your bush will be a new duster as well.

I agree with the one comment, Kilz latex is garbage. I have had really good luck with bin 123 in the past. Also if the home owner is worried about fumes I'd stay away from anything shellac based. Also I find the shellac bin has a tendency to spray, a lot. So if you do use it make sure to overkill on masking off. Good luck man, its sounds like a fun job.

rstarre

I used Kilz over water stains and the stain came coming back. I agree, kilz is crap.

chris n

Just to clarify Bin and 123 are 2 completly different primers.

Greg as for getting the Customer to understand that would be up to you and how convincing you are. If you can explain to the customer then there should be no problem selling them on that product. You need to understand what the Customer wants Cheap price or Quality job? so if they are middle of the road put that facts on the table and leave the ball in their court. Don't make this dissension for them.
