I'm in the process to repaint my exterior, does anyone know how to get rid of ivy roots on the blocks, I tried water blasting, but it didn't come off. Apart from this, can you guys suggest a tutorial or guide on painting concrete block
Hello @mike1360
Thanks for sharing your question about painting concrete blocks. One of the issues with ivy roots is that they really get into the substrate of anything they grow on. You'll need to use a nylon bristle brush in combination with a plastic scraper. I'm afraid It will be necessary for you to mechanically remove the roots from your wall.
Once you've removed the roots, I suggest using 30 Seconds 5L Outdoor Cleaner Concentrate and scrubbing the wall with an Oates Long Handle Deck Scrub Brush. Give it another blast with your pressure washer and when the wall is totally dry, I suggest using exterior paint to paint your wall.
Here is a handy step-by-step guide: How to paint a room ( the techniques used are applicable when painting outside )
I also suggest having a look at this discussion - How to remove vine remnants on house? by @Mela18

Hello @mike1360
Both finishes provide the same amount of protection when it comes to mould, dirt and stains. However, with a gloss finish, dirt is more noticeable as the glossy finish on the surface begins to fade. The semi-gloss finish does not provide as much sheen and maintains its neutral finish much longer. I propose going with the semi-gloss finish for easier maintenance.
But when the gloss finish is used on the inside of the house, especially in the bathroom and kitchen it makes cleaning the walls that much easier.
