I'm finding the product way too thick especially for either rolling or brushing over tongue & groove pine doors.
That’s funny because I’m holding a can in my hand and it says dries to the touch in 30 minutes can be topcoated in one hour. Nowhere does it say wait 4 to 24 hours. Wish I could have a pic to show you.
We use this paint for covering nicotine walls and ceilings, yep he could have explained this a little bit better I'll try and do it for him, when you roller a wall with emulsion, then cut in around the ceiling skirting and corners, almost every time you would find the wall is dry but around those edges where you cut in with a brush it's still wet, and probably 99% of the time you won't get damp or stains in the middle of a wall it's around the corners top corner of the ceiling bottom corner skirting board where most people are trying to get rid of those stains, and of course know the paint has been put on thick it's not dry,,,, as a rule of thumb yes it's dry within 30 minutes depending on conditions whether type of service etc, as long as the said areas are dry it should not bleed through, here in the UK all the decorators that I know only used this as a primer, as an example, toilet leak and the system what they put those blue tablets into came through the ceiling, used a couple of different stain blockers but this was the only one that covered it, and that was years ago and never use anything else apart from this stuff,,
If I paint over it with white latex, will it turn my white paint yellow?
What is best primer for painting over water based paint that was painted over oil base and is now peeling..
Scrape it off
Scuff it with a low grit sand paper like 80, then go over it with a 120. Then primer it with an enamel primer like stix
Move house,
is the Cover Stain a better product than the BIN primer for covering furniture before painting, to stop bleed through.
For some reason, the BIN is always recommended rather than Cover Stain but I think that is a meths based product, which makes brush cleaner a bit too much faff.
BIN is better by far. BIN is thinner, cover stain is rather thick, ropey (as in, leaves too many brush marks.) BIN can't really be used outdoors or even really in high moisture places like bathrooms without a good exhaust fan, whereas Cover Stain can be, BIN's shellac will sometimes lose bond with too much moisture. BIN dries faster, and has a sooner time to sand to powder. Cover Stain dries to touch or recoat in a couple of hours, but it's 3-5 days to sand to powder generally, whereas BIN will almost always sand to powder the next day no problem. Also BIN is significantly easier to clean up. Cover Stain is oil based, and you need mineral spirits (I think meths in UK) to clean it, but BIN you can clean your brushes with either alcohol or for much cheaper, ammonia ($1-2 per gallon.) Cover Stain also smells very harsh even compared to normal oil based paints, BIN is a lot less harsh smelling by comparison.
@@GilBatesLovesyou Cover Stain has up to 3 times more coverage according to the data sheets. That's a big plus to me. More people are familiar working with oil based paints than shellac so that's also in Cover Stain's favor. We use White Spirit here in the UK to thin oil based paints. Naphtha can also be used, whether it's light or heavy, they're both stronger solvents than mineral spirits. So, you would use less.
@@bitTorrenter I've heard of situations where Cover Stain has weird adhesion issues from people thinning it. I've thinned it before with mineral spirits and naptha, it works, but BIN is still better, it sands way better than Cover Stain and applies smoother. Coverage with an oil primer to me is pretty much irrelevant, as I'm usually using them as a bonding primer or a sanding primer. Theoretically you could get any paint to cover by thickening it with cheap fillers like chalk or talc and making it a thick viscocity (Cover Stain is also almost yellow for this reason) it doesn't make it better paint than a thin paint with a high amount of titanium white.
Cover Stain specifically in USA also has been reformulated in low VOC states to be simply dreadful and nasty to use. It has poor adhesion and coverage now, but it also smells really bad and burns your lungs. Zinsser in US formulated it with some sort of dry cleaning solvent that's still VOC exempt, but this solvent is absolutely noxious compared to presumably mineral spirits/etc. Also, the price of the "low VOC" version went up, it used to be about $20 a gallon, now it's about $30, whereas BIN is about $40. So for the price difference now, BIN is a superior product. I've heard better things about Benjamin Moore's Fresh Start oil primers, which are also about $35-40 a gallon, so I'm more inclined to use them over Cover Stain if I absolutely need to use oil primer.
EDIT:
I also found the Zinsser Odorless oil primer much nicer to use than Cover Stain. Brushed and handled way smoother for some reason, and also didn't smell. But I currently can't buy this product beyond quarts in my state in USA due to the VOC rules.
@@GilBatesLovesyou yes i had problems used to prime exterior woodwork had to thin it and it failed after few weeks went back stripped it used a traditional primer had to thin it as do after a while and it was fine much nicer to put on to. you can't use coverstain without thinning after a while if using it instead of traditional oil primer.
