The house was built in 1948, and following additions were constructed of wood and sheet rock. The block in original section of the house is cracking and not weather effecient, we'd like to cover it.

    I would stud the entire wall, insulate it and hang sheetrock

    I agree with Ann. First I would seal all the cracks in the block. Glue on 6 mil plastic on the block as a vapor barrier. Then I would glue on 2" foamboard on the block walls. The screw 1X4's flat over the foamboard, then drywall.

    I would probably fir them out with 1 x 2 strips anchored to the wall and install drywall over them. You could stucco them if you feel up to that challenge. I'd hate to lose any of the depth or te hinges on those lovely built-ins, so I might also explore a textured and paintable wall paper.

    We have the same down here in Oz,.

    My concern is for your built-in's. Plus the area you live in may get damp in winter, and cause more problems behind the dry-wall. I know you can insulate but that is not always workable...with damp, and these blocks!

    I would look at saving up and find a professional to render the wall.That is not something one should do, unless your quite well versed in it. That is a key wall in the home, so that is my take on this problem....all the very best.

      I agree completely with Pat, you can hide the real problems but it won’t fix the real problems you have and there likely to keep getting worse after you cover it up! You could very well loose all the money and labor covering it up having to remove it when having to fix your cinder block wall. If you go this route I’d keep it simple and cheap as possible and consider it a bandaid till you can get the funds and help to fix the wall correctly. May want to consider removing the cinder blocks all together and putting in a traditional studded wood wall with siding and Sheetrock on the inside? since it’s a load bearing wall it’s may need supporting before doing much removal of the existing wall for repairs

    After you insulate, I would consider covering it with white beadboard. I love the white open air look of the room

    I would 1st apply DryLock (Home Depot or Lowes) to the walls. This will seal the block and prevent moisture. The least expensive thing then would be to texture the walls and paint. I did this in a basement and it worked great. If you prefer sheetrock you can fur in with two inch studs, put an insulation board between and cover with sheetrock following the DryLock. After much trial and error I have found DryLock to be the best product for block walls.

    Hello. Being a DIY person on a home I owned I had to waterproof my basement walls from dampness to save thousands if $$$. I used the rustoleum version of flex paint which I bought at home Depot. It worked great at sealing the gaps in the cement block, but it took about 3-4 days for the aerosol paint spray odor to disappear. If I had the forum if flex seal paint in a can that I could have painted with a brush, it would have maybe not smelled as bad. But, it worked in sealing off dampness. Dry Lock cement Block draper paint didn't work when I did use it before , but since the flex seal paintdid I would recommend it. Do it in the summer, when you can open all the windows in the room and have a fan blowing on it to help it dry quicker, and vent out the fumes. Good luck.

    Sealing the wall first then add bead board and it’s paintable📌
