Looking for primer information?
I think there was a great informative post on the comparative cost and quality of a few popular exterior primers...but I can't find it now!
Could someone please point me to primer information, if they know how to find it? :)
What's great to use, good to use, or good to avoid?
As with most paints, the cost should be low on the consideration totem pole
The correct/best product for the job, and/or that suits your needs, should be the highest
Usually it's best to go with a national company with premium lines that professionals use, but within those lines you will find many different primers, each with it's own specialty
It would be much, much, easier if you mentioned what your needs are at your local Paint Store (don't bother with the BigBox stores...they don't have the best product or knowledge), or simply post up what you are doing here and we can suggest a few
As a general rule, you can't go wrong with Ben Moore's, Sherwin Williams, or Zinsser's primers, but again, it's which product from each line is correct for you is the tricky part
Any 3, 6, or even more dollar difference in price hardly matters if the entire project fails due to the incorrect, or poor quality primer
Thanks...this is in talking with someone who just bought some Valspar primer and started putting in on their house, at probably close to $20/gallon cheaper than what we paid for our SW primer...
Their primer is a lot thinner than ours, and is not covering very well. Can they put a better primer over their layer of Valspar, or will they need to sand that down first?
I can't imagine why there could possibly be a $20USD/CD difference in retail primer cost
$7, yes, I could see that...depending on product, name, retail outlet, etc...
Either the SW primer was way over priced or the Valspar primer is complete garbage
To answer your question (which seems to indicate the V=garbage choice), it really depends on why they were priming in the first place
Simply priming, even with a good primer, over a cheap, ill-adhering, primer won't increase the effectiveness of said cheap primer
And even poor primers can hold OK (just not worth the risk)
To be on the safe side, I would probably go over the Valspar with a specialty primer that penetrates the substrate to hold it better
I'd suggest Zinsser's Gardz
But again, not knowing what/why they primed I can't say that's THE answer
You're right...it was less than a $20 difference! Maybe closer to a $16 difference without a sale. Or maybe $9 or $10 difference with a Sherwin-Williams sale. Sorry for the exaggeration!
We used SW A100 exterior latex primer, which sells for 35.49/gallon at full price, without a sale going on. We got most of ours on sale at $28.34/gallon.
They said their Valspar was something less than $20/gallon, but I'm not sure how much less. I'd say they probably used primer to help with color change and to prepare for exterior paint. Not sure if they are covering over old latex or alkyd!
If it's exterior, I'd sand off the Valspar, no question about it
At least a good go round with an orbital to scuff it up/off
I'd need more information to recommend a primer for that project
I might let the interior stuff stay if it's still holding after a week
But I wouldn't trust that exterior stuff...too much of a hassle to fix it if it fails
The A-100 is a fine product
Although SW marks it up a bit at 34/36 so they can get the 27-29 "on sale"
I'm usually better at math than this, but.....I'm getting different answers and different prices on different days. Not sure how we previously bought the same thing for $28.34, but that's what the receipt says.
I've heard way too much of this from Sherwin lately. They are doing some odd things with the prices in this area as well. It makes business better for me though. I'll not that the pricing on Pratt & Lambert primers (owned by SW) have been going wacky as well. So I don't sell them anymore. I'd say stick with Zinsser if the pricing on the SW is so bad.
