FrederikKitten Posted August 28, 2022 Share Posted August 28, 2022 In my life I have only painted nice walls. And this time my walls in entire house are quiet a mess and I'm lacking experience here. Will the standard primer + color hide this? There was a lot of renovation done + there is a lot of kids drawing on some walls. Or should something else be done before primer + color?

Popular Post EVENKEEL Posted August 28, 2022 Popular Post Share Posted August 28, 2022 I don't see a problem. Clean off grease and dirt, at least sweep it first. Get the good primer and paint it, probably take 2 coats of primer before main color. 4 Link to comment Share on other sites More sharing options...
sometimewoodworker Posted August 28, 2022 Share Posted August 28, 2022 Be careful that the kids didn’t use wax crayons, or if they did the cleanup will be a bit more of a problem 2 Link to comment Share on other sites More sharing options...
Popular Post Sparkling Posted August 28, 2022 Popular Post Share Posted August 28, 2022 Wouldn t worry. Sometimes i was surprised what primer and color actually cover when they dried. Yet i would recommend two coats of color, if nessecary, rather then two coats of primer, because of course the real pigment is in the color AND i was told by a worker, it is not good to use two much primer. Still, if wax crayons are on, it is better to get off as much of it as possible with some paint thinner or alcohol. The color will cover the rest. Just try it out. 3 Link to comment Share on other sites More sharing options...
rwill Posted August 28, 2022 Share Posted August 28, 2022 (edited) You can find several methods online to try and remove the crayon markings first. Primer and paint will make the wall colors match where the work was done but you will always see the lines where it was done. Unless you resurfaced the whole wall. In my living room I had a doorway and the light switch covered up and you can still see where it was. But it doesn't look that bad.

Popular Post Asquith Production Posted August 28, 2022 Popular Post Share Posted August 28, 2022 It depends on what you want to hide. No doubt you will be able to paint over the crayon but nothing will hide the uneveness of the walls. I would get the room replastered. 2 1 Link to comment Share on other sites More sharing options...
Popular Post Dante99 Posted August 28, 2022 Popular Post Share Posted August 28, 2022 before primer, sand the wall with sandpaper to remove loose bits and smooth all new cement looks pretty normal to me but have not seen the kids art 4 Link to comment Share on other sites More sharing options...
itsari Posted August 29, 2022 Share Posted August 29, 2022 Use two coats of undercoat and two of finish coat and you will have a good result . 1 1 Link to comment Share on other sites More sharing options...
Popular Post dzodun Posted August 29, 2022 Popular Post Share Posted August 29, 2022 As a painting contractor in the US for 40+ years I would recommend the following: try to clean off any markings with lacquer thinner; sand said areas as necessary to present a smooth appearance; spot prime/seal all such areas after cleaning with TSP (or equivalent). Primer should be oil or lacquer based; of course any cracks and damaged areas should be taped and patched as necessary, and sanded for smooth appearance. Then apply one full cost of a latex based primer, tinted towards final color choice if possible. Finally, apply good quality finish coat(s) of latex paint as needed to present an even appearance. Oil based paint can be applied if so desired but I prefer water based to avoid strong odors. This process may be a bit of overkill, so some steps may be unnecessary. Choose one bad area and experiment. Then proceed as time permits. Be sure coatings are fully dry before continuing. Good luck! 4 Link to comment Share on other sites More sharing options...
thailand49 Posted August 29, 2022 Share Posted August 29, 2022 This is nothing new typical of how they install the electrical in the walls or filling in a area which was a window? There are two types of primers for new cement or old of if Thai doing the work they will know what to use the area does needed to be scrape down and smooth of the access so once applied you won't see the outlines.

AhFarangJa Posted August 29, 2022 Share Posted August 29, 2022 Purely from a personnal perspective I would have the walls skimmed, after removing the crayon. Link to comment Share on other sites More sharing options...

Tropposurfer Posted August 29, 2022 Share Posted August 29, 2022 Single coat of quality primer (straight out of a well stirred tin). Don't skimp on the coverage as many amateurs do. Crayon - WD 40 lubricant spray on a plastic kitchen sponge/scourer will remove the crayon easily and entirely. Make sure you clean this surface area after with some alcohol to remove the greasy film the WD puts on the wall. Use quality interior mould resistant, washable, wall paint x 2 coats (will resist the kids drawing and make it easy to remove other marks as the years go by). Apply paint exactly as instructed out of the tin (stir well, don't try and make it go further by thinning it). 2 Link to comment Share on other sites More sharing options...
paulbrow Posted August 29, 2022 Share Posted August 29, 2022 I'd recommend using a good quality sealer first. They are designed to prevent bleed through. Them prime and finish coat as usual. I used to paint professionally and a good sealer will stop crayon, magic marker and all sorts of nasty stuff from bleeding through. Here's a quick link to the paint guru site you might find helpful: Stain Stoppers: Primers That Block Bleed-Through - Paint Gurus (typepad.com) Good luck!

TigerandDog Posted August 29, 2022 Share Posted August 29, 2022 we've just had something similar done. Didn't need to re-render the walls. First the walls were sandpapered. Second they were painted with a protective skin. This was applied to stop the cement render from absorbing the moisture out of the paint. Third 1 coat of undercoat was applied & Fourth 2 top coats were then applied. Link to comment Share on other sites More sharing options...
peterfranks Posted August 29, 2022 Share Posted August 29, 2022 I think most here miss the point that the writing on the walls will be a small problem, and the bigger problem will be all the repairs done. Those you will not be able to hide with a primer 1 Link to comment Share on other sites More sharing options...

Use a quality primer and paint over a small section and see the result.. that will give your answer. If no good you may need to screed the worst areas.

Thingamabob Posted August 29, 2022 Share Posted August 29, 2022 From the photos I suggest wall cleaning with detergent/ water/gentle scourer. When dry, apply primer for old walls. Inspect, and, if ok, apply colour. If not ok, apply second coat of primer, followed by colour. Link to comment Share on other sites More sharing options...

If it's only the colour differences on the wall that you are trying to hide, then primer and enough coats of paint will hide that. If you're trying to hide faults in the wall and areas where work has been done on the original wall, no amount of paint will hide that. 1 Link to comment Share on other sites More sharing options...

Photoguy21 Posted August 29, 2022 Share Posted August 29, 2022 A thorough cleaning of the walls then plastering or at the very least a good quality paint just to make a base. Link to comment Share on other sites More sharing options...
paul1804 Posted August 29, 2022 Share Posted August 29, 2022 (edited) It all depends on how good a finish you want?? Are the repairs and the walls even, if not and you want a good finish get a plasterer to plaster the walls. Remove the crayon as it will probably effect the adhesion of anything you put on the wall wether it be plaster or paint. You could buy a sealer primer and give it a coupe of coats a day apart and see what it looks like. Alternatively If the walls aren't bad get a course hand sander and give it a good sand, if it comes up ok then just put your primer sealer on and then top coat it. Good luck.

In Full Agreement Posted August 29, 2022 Share Posted August 29, 2022 I would highly recommend you be sure to have the primer tinted in the color you want as the final color. Link to comment Share on other sites More sharing options...

It's hard to judge how even the wall is from the photos, but you can sandpaper it - it's always advisable by professional painters to sandpaper plastered walls before painting - if it's even, then primer and paint will work. If not, you might need some skim coat. I would do two layers of primer with one day separation, wait another day and thereafter two or three layers of paint...????
