Thread: should I be expecting something better than this render?

  1. #1

    should I be expecting something better than this render?

    Just having some garden works done (yes from previous threads, we removed the poorly fitted Millboard decking) and have had patios etc laid.

    Part of the work is building an outdoor kitchen however I have been out there this afternoon looking it over and to be honest I am none too pleased with the finish. There are a bunch of bumps and dents, a few gouges and even a crack has appeared. This front face was completed Friday so obviously it wasn't hot so no idea why is cracked but the rest of it looks shoddy.

    I've never had anything rendered before and I am not expecting an interior plastered smooth finish but it shouldn't look like that right?

    Few shots below hopefully demonstrate what I have. Builders keep telling me 'Oh K Rend isn't smooth' etc. I realise that but I at least want flat (and with out cracks )

    K Rend is not smooth but if done correctly itís flat and doesnít crack, and definitely doesnít have holes in.

    K rend is at the lower end of renders, but the finish should be way better than that. I have K rend on my house and itís 8/9 years old now. And itís a better finish than yours.

    I find the K rend a little washy, not completely uniform, and it certainly goes green if thereís trees nearby, but thatís a poor finish in my opinion

    Sto and Weber renders are supposed to be better, in case anyone is looking or thinking of render

    Not quite what you might want to hear, but we've always had render (both smooth and textured) painted over with a decent exterior paint - a by-product of which covers up a lot of imperfections.

    Those pictures show very poor workmanship, far too many tradesman think K-rend or equivalent modern renders are like using sand & cement. Itís a completely different product and requires a decent level of knowledge on how to prepare surfaces, laying on the render, and then applying the finishing look. Most suppliers like K-rend and Webberís offer courses for their products and specialists will pay decent money to obtain accreditation from these companies. Looking at those pictures there is only one way forward, remove all previous render work and get an approved tradesmen in to complete the work if you want a professional finish & look that will impress you and your friends/family.

    One the first coat of K Rend a reinforcement should be applied to stop any cracking.

    I thought K rend and Weber (pral0 were pretty similar. More expensive than traditional sand and cement render. As mentioned previously, the base coat has, or is applied over a thin plastic mesh to prevent movement I assume. The top coat applied the following day is left to a flat/even finish. Following morning it is "finished up" by rubbing with a metal float that has metal spikes on leave a mottled finish?

    Shame you've had to tae up poorly fitted Millboard. Thats not a chip product by any means. pity theres people going around who don't understand products and materials...

    As others have said that's poor workmanship.

    Yes, absolutely, that is one awful job there

    I agree that is not a good job with k-rend.

    Also if the finished item is uncovered make sure the tops are capped (although I would expect an outdoor kitchen to be covered) as my experience with K-Rend was misreable for the external walls and very intolerant to getting wet but fantastic for the house itself.

    Any cracks will hold water and when it freezes just fall off. If it does it to roads you can imagine how that will fair.

    Thanks for the comments chaps. All solved. Got them to remove it and I'll be getting it tiled now instead! Seemed to be a pig to chisel off

    Happy with the outcome though. However now need to make another decision on tiles .....

    Thanks again.....

    Is there a reason not to tile over the render?

  14. #14
    From my perspective, if it was cracking now it wouldn't be a good base to then add tiles on top of. I'd rather start again with a clean slate. Plus I think KRend has silicone in it? Not sure if that would cause issues with adhesion? I am sure an expert will be along soon to give a proper reason though

    If as you say itís a pig to chisel off then it would appear to have stuck well. And I canít see any issue with tile adhesive not adhering to that rough surface.

    For me Iíd only be thinking about removing the render if Iíve already sourced worktops based on the current dimension minus tiles.

    Good to hear you have the dodgy rendering issue resolved. Just make sure you get a decent tiler who uses the correct adhesive to withstand the rigours of our lovely ever changing UK weather !
