what about primers for non-porus surfaces like metal? --Gbleem 00:39, 28 July 2006 (UTC)[reply]

what about paints like floor paints where primer is not usually used. --Gbleem 00:39, 28 July 2006 (UTC)[reply]

The article says little about the chemical compositions of primers and their design for different applications. Xxanthippe (talk) 03:24, 18 January 2008 (UTC).[reply]

regarding floor paint... most wood floors are made out of Hardwoods that are then further sanded and although it is wood and it is porous it has a much sturdier surface then what you'd find on other woods that might be painted and as such may be less likely to need a primer. also, any floor paint is designed for durability and because of that, the layer thickness is many times the thickness of the layer of other painted surfaces. there are also that go on concrete floors but the floor has to be prepped correctly before the paint which itself has additional solvents and binders in it can be applied Tapalmer99 (talk) 17:51, 25 December 2018 (UTC)[reply]

I would like to see in this article a paragraph on the effect of primers on the wettability of bare surfaces. Paint often forms droplets or beads rather than a uniformly thick layer on bare metal or wood, due in part to large differences in surface tension between liquid paint and solid surface. Primer apparently reduces that difference. An engineer or scientist from one of the paint manufacturers would likely be qualified to comment on this.--His Manliness (talk) 22:42, 9 June 2009 (UTC)[reply]

this article is not written in the correct style for wikipedia.

This section seems almost deliberately unhelpful: the need for primer is determined by the composition of the polymer, additionally it needs to specify whether the primer is cellulose based or acrylic based. (a5y 18:08, 27 February 2007 (UTC))[reply]

all that information would come from the manufacturers of the given coatings. with such a wide possibility of materials end coatings, it is not the place of Wikipedia to provide information for each individual product and option of which coating would be more appropriate Tapalmer99 (talk) 17:41, 25 December 2018 (UTC)[reply]

I was hoping to read about how primer is made, not just a list of its uses (which is also important). — Preceding unsigned comment added by 24.191.198.17 (talk) 08:38, 23 October 2011 (UTC)[reply]

the process of making primer is very similar to that of making paint.

I am currently looking for information from a few of our suppliers and I'll see what they may have in the way of the manufacturing process. I believe there was an episode of the show "how it's made" where they were producing paints. Again, the process is very similar. Tapalmer99 (talk) 17:44, 25 December 2018 (UTC)[reply]

You dont say anything about what kind of primers are used for papier mâché or cardboard projects. — Preceding unsigned comment added by 101.63.152.145 (talk) 10:00, 21 May 2012 (UTC)[reply]

I propose we merge Stain-blocking primers into this article to keep information about paint primers in one article. Stain-blocking primers was started in 2009, needs cleanup and references, and is an orphan. Jim Derby (talk) 02:06, 18 January 2014 (UTC)[reply]

Although stain blockers are primers, are they primarily primers? Or are they rather sealers – that can be applied over a bare surface, as a primer, as an incidental. Andy Dingley (talk) 20:16, 12 May 2014 (UTC)[reply]

In the article its mentioned that primers can be formulated to promote certain characteristics that would not be achievable if they also had to act as finish paints. This is not a substantiated claim, especially since there are many finish treatments which include a primer function. And its not made clear why a single surface treatment could not have all the desired characteristics of primers and paints from a chemistry or formulation perspective. — Preceding unsigned comment added by 104.173.48.93 (talk) 22:49, 8 July 2015 (UTC)[reply]

You're right that the topic needs more coverage. But I'm pretty sure that this is sometimes true, even if manufacturers sometimes overblow the significance of it. I believe that single-stage systems, which work perfectly fine for many purposes, make some trade-offs that are acceptable in many contexts although not all. The variables involved include strength of adhesion to the substrate, opacity versus lucency, and color palette range. For some substrates, the way to make the most adhesive primer requires opaque ingredients. If you then want a color layer of a certain hue, plus a clear layer, you can't combine all the stages. The first stage (a dedicated primer) maximizes adhesion over color; the second stage (paint) maximizes color palette achievement and has less work to do regarding adhesion to the first (because the first is pulling the load there, making it easy for the second), and the third maximizes lucency and UV resistance (to keep the second from fading) while also being good about wear resistance. For example, metallic paint jobs cannot combine the primer and paint into a single stage. — ¾-10 01:06, 9 July 2015 (UTC)[reply]

I began at an English iw (interwiki) link at the Spanish WP Imprimación. I think is a wrong one. I'm thinking to change it, but there're two English articles. ?'ve stopped. I've written this, there:
VOC, one section'bout VOC's, Primer & Imprimatura
Volatile organic compound, one section: Stain blocking primer#VOC's, Primer (paint) & Imprimatura

• Volatile organic compound (Q910267), this article: VOC = Volatile organic compound
• Stain blocking primers (Q7597001): one section'bout VOC's = at Stain blocking primer: (you see: suggested to be merged into Primer (paint). Proposed since January 2014), small & orphant one.
• Primer (Q380866): Primer = Primer (paint)
• Imprimatura (Q11711948) : Imprimatura

Merge? : Which? Where?. (Stain blocking primer & Volatile organic compound . . ( ... or with: Primer (paint))), (Imprimatura & Primer (paint)). vgr.: Stain blocking primer#VOC's with Primer (paint), or that section to VOC article. Or better, with both? And with Imprimatura, too?. I began with this section title Merger proposal (notes'bout) of Imprimatura [et al] because I know, this commentary is not a formal merger proposal. But thai's all, I've got now. --PLA y Grande Covián (talk) 16:04, 17 August 2015 (UTC)[reply]
