Hi guys, Few years back i painted my bedroom wall a dark red color. Immediately white patches begin to show up. I tried wiping them off but it came back shortly after. I didn't use any primer for that paint job. Now i am sick and tired of these ugly wall and planning to paint them. After reading thru forums, i believe the root cause is the absence of the primer cause the water from the previous paint job to seep into the new paint. My question is, before I prime these walls, do I need to completely remove these white patches first, then prime them or just leave it as it is and paint over them? I am afraid I might make matters worst since i will have to wipe them with water, and prime them after would cause more disaster since the issues is water to begin with. Also I realize that place where my head always lean on the wall when I have hair oil(olive oil) seems to clean of the white patches really well. I thought maybe I should wipe my walls with light coat of olive oil and then start with my paint job (primer included this time). Do you think this would cause any problems? Next what primer do I use? Is water base primers that claim to be have amazing sealant power be sufficient? or is it a must to use oil- base primers? I read it's a huge hassle to use oil-primes, I really am leaning towards water-base primer because of this. I am looking at Benjamin Moore paints which are latex base-paints. Can I use a latex-base paint as a top-coat over a water-base under-coat? same goes for oil-base under-coats, is it advisable to use a latex-based top-coat? and have anyone tried using Benjamin Moore paints? which ones do u recommend for our normal HDB wall. You can see I am truly armature here, I hope anyone who is knowledgeable can shine some light on this. I have also attached the photo of my horrific wall.
Hi all Appreciate if anyone could advise on my current situation. I bought a 3-room resale flat that was vacant for at least 6 months. I noticed the presence of booklice along the kitchen grout about 2 months after completion of reno. They have now invaded the whole house. I see them mostly on the floor, and along skirting. Vacuuming, and 2 dehumidifiers do not seem to work. I cannot seem to locate the source, though I suspect it came from the main drainage area. I started noticing a few light yellow splodges on 1 of my hall's wall. Today, I used a masking tape over it. The paint came off, and there were black spots. I have a pest control coming in to mist the place tomorrow. My questions are: 1. I presume those black stuff beneath the pain are mold? 2. As the splodges are small in size and a handful currently, can I just scrub it off with a mold remover? Or are the splodges an indication of a bigger area of mold? 3. With the presence of mold, will the misting tomorrow be rendered useless? 4. Has anyone successfully eradicated a booklice infestation? They are making me very paranoid. Thanks!
