How do you fix this? Do i have to sand or scrap all the green and old paint before repainting? Apply any product that only magic paint men know? I have already fixed the roof leak
>>2992683 Is the corner of a warehouse that i am using it for fun stuff (home cinema, pool table,..) i want to put gym equipment in that corner but is ugly as fuck right now.
>>2992682 Scrape it with a putty knife. Scuff it with a scotchbrite pad or wire brush to knock off any additional loose stuff and then brush on or spray on new paint.
>>2992684 Your ugly ass gonna be in there with it. You could rebuild that wall from scratch and cover it with gold leaf and it would still be a net negative.
>>2992682 you could throw almost anything opaque over it and it would eventually be fine, but ultimately this is a question of aesthetics and theres no way to give you real advice without knowing what the hell you want it to look like when completed, for example, if you where a weeb i'd tell you to throw shoji or a wall scroll or something over it. a western scotch and a cigar larper then a book shelf to go with your pool table and bathrobe rack. it all fucking depends asshole.
>>2992776 I want it to look plain clean white. I am going to remove the heater and the pipes, and just leave the electrical box, give it a good cleaning. I am going to make it as nice as possible with what i have there, the question is about how would an expert go about repainting this stuff so you get a good (just plain clean white) durable result. I am sure there is some special knowledge pros have about it.
>>2992682 >>2992779 bleach the algae to kill it, then sand it, then put on an oil based primer like kilz or zissner coverstain, then paint it and you are done
>>2992863 I am making some progress. Turns out i can sand out most of that shit, the concrete underneath doesnt look that bad. However i will look into these products you mentioned.
