Maximum half a cm if that. They’re only dinks really. There is some bare plasterboard where the builder rubbed off the paint when trying to clean off some grout. Very small amounts here and there, but might need priming first? I sometimes sand a little too much too and the plasterboard shows through. Would a photo help?
Oh right, so they mean 25% of the amount of paint not a 3:1 paint:water ratio as that would be 750grams:250grams. 25% seems like a lot of water to water the primer down with? Do you always water your acrylic primer down before applying? and subsequently do you water down the emulsion before applying on top of the primer or apply as is? Have you found the Toupret to show through when you’ve painted straight over it (no primer)? Though i’d happily use acrylic primer if it’s fail safe. If I were to spot prime (as some of the walls are large so don’t really want to coat the entirety of the wall) the primer won’t flash through?
I also brush off the dust rather than use sugar soap or anything similar. Is that alright? I’ve used water/sugar soap in the past and it just causes more problems because the old paint just wipes off leaving bare plasterboard. I also usually sand the wall down so it’s completely smooth. Is this bad as there won’t be a key for the new paint to grab to?
Sounds like you are making up the sugar soap way too strong and hot, contact matt will wash off as it has no vinyl content. Washing the walls with sugar soap is pre preparation not after. The posts read like you are over thinking the job and that's what's giving you problems.
I am definitely overthinking as decorating has always gone wrong. Even when we’ve got a decorator in that’s gone wrong. I don’t remember the sugar soap being warm at all. It just wiped paint off as it would do with contract matt. Hence why I switched to brushing it off. If the walls are too smooth would the new paint have trouble sticking to it? Please could you send over a list of bullet points describing exactly what you would do in my position, step by step. I’ll follow that. (Including when you think paint down and when not to etc.)
I doubt in this case if the walls are too smooth. As for bullet points that's a @Diydave quality as he writes much more fluently than myself. Painting over contract matt really does soak the paint up apply a thinned down coat of emulsion as the first coat of circa 15-20% and let dry a second cost thinned 10% would be fine.
How should I contact DIYDave? Do you really need to thin the second coat down? By thinning the first coat down 15-20% that’s almost like doing a mist coat isn’t it? If I did go ahead with the acrylic primer, depending on how much filling is needed and bare plasterboard is showing, I‘ll do one coat and water that down 25% (seems like a lot)? what would I then do watering down wise for the emulsion?
Crown Trade paints will take thinning well, you must read and take on board what's been written in the advice given as you are going over what's been answered in prior questions.
I’m confused to be honest. As I understand it, I have a couple of options: Option 1 - paint emulsion straight over the Toupret filler (no need to spot prime). Thin the first coat of emulsion down by 15-20% then the second by 10% Option 2 - spot prime the filler with acrylic primer. Thin down by 25%. If most of the wall is covered in filler then it’ll be easier to apply primer to the entire wall. Then I’m not sure if the emulsion needs thinning or not
As said in an earlier post it's to achieve the consistency that the decorator judges to work for him, it avoids a stipple finish from a roller application and visible brush strokes, improves flow etc, remember 2 light coats is far better than one thick/heavy coat.
Makes sense, I’ll dilute each coat. As long as it doesn’t affect the scrubbable qualities of the paint. I’m going to do a small test under the stairs on a small 30x30cm area of wall. I’ll leave some of the Toupret bare and spot the other patches with diluted acrylic primer. I’ll then apply 2 diluted coats of emulsion to both to see if 1. the Toupret reacts (swells) with no primer 2. the Toupret flashes 2. the emulsion covers the spot primer well and there’s no flashing from the primer Sound good? then I know in the future what works, so if I do decide to go without the primer I know it’s okay to spot prime in the future.
Search for Toupret Interior Filler online, it will tell you exactly this, whereas Easifill is a different beast, that why I do not use it anymore.
Yes mostly. Sometimes I want it to be a bit bumpy to match in with the reset of the wall on tart ups so no in that case.
