What happens if you leave K-Rend too long?

[@DafyddBr]

Good to see that you aren't too proud to do videos showing mistakes (and how to fix them!) Good job as usual!

[@darrenthebuilder]

We all learn from them and hopefully I help someone not make the same one lol

[@Spencerlayne]

You're a hard worker bro. Any customer to have you should thank them selves lucky. Mad props man

[@Ireland-bc2gx]

A right pain ,hard to beat sand and cement floated, and a coat of paint

[@MrGeoffreySmith]

In the past I have used the blade off a bow saw. Rolled into a circle and tied together with some wire. Very aggressive but controllable.

[@user-rx1ob3ix8m]

You’d be better off beading up again with 6mm beads reapply small layer, leaving to set and scraping before it sets, you won’t have scraping difficulty all day and only costs half the original materials to rectify

[@themudhutt1]

I think we can all agree you have a work ethic to admire and the patience of Job . Talk about everything going against you . Good finish so far though

[@leedrummond164]

K rend u really gotta be scratching the same day unless its really cold. You gotta come really proud with it too so that when you scratch it back its flush as you wanted. Not bad tho fellla. Love all your videos.

[@goldenineke]

That ended up being hard work Darren but the end result is great! I love the grey render b

[@kristianwhittall9025]

well that looks terrible, not being troll but ad some accelerator same day, take the skin off it 3-4 hours later, bar it with an I section then leave it 1-2 hours depending on temps and scratch up very gently!!!!!! Grey is a crap colour anyway and casts shadows. the best solution to cover this would be a Krend primer then a thin coat Tc15 type product which can be put on directly on to scraped texture as long as its not been painted! K-rend provide a data sheet for this. I would bite the bullet and pay out my own pocket. I have been in this situation and that's why my view is what it is. Seen your work before and ive seen you do some good graft in the past.

[@plummetplum]

Watching this video I understand a bit more about K rend having seen the finish. It does have a nice finish I admit. I remember seeing a black coloured render on a building the other day which looked really nice and I wondered how it had been done. Now I understand that that was K rend for sure. Please invest in an FFP3 mask, all that dust in your lungs is a killer. I use the JSP force 8 from screwfix. All the best 😉😉

[@Jezz_Mcfly]

Mask up for sure ! √

[@deanevans7707]

Hard work mate. Always a fine line between cured and not. Weather against you to Darren but sure you ll learn from this one its how we all do.

[@TheBiglfb]

Hard work but i think you pulled it off in the end... well done!!!

[@johnr1992]

Your Krend was out of date, that's why it went off so quick! Look at the Date on the bags.

[@johnr1992]

Sorry my Bad! I thought the date was best before.

[@MrSheppard1980]

4-36 hours isn't a choice mate. You have to scratch same day or next morning at the very least. U can't choose... also no basecoat means every time it rains the morter joins will grim through. If u need any tips call Campbells Plastering

[@Happytruth]

Is this job hassle because of the drying times and weather? Everyone seems to promote it as easy and they’re all making a fortune especially the ones that are spraying it on but finding the truth is hard as honest guys now are hard to find. I’m old school only done sand and cement in the past and fucked that off because of the weather and prefering to work indoors.

[@shelleyshell1150]

That was some intense manual labor 💪🏽. It’s great the way you are determined to finish a project correctly! Great job and I like the grey !

[@scosy07]

Left far too long and that’s why it was so hard, all about timing woth scratching, the discolouration and pits tbh this ain’t a good finish at all

[@lukedacosta3729]

Love your honesty

[@JayE1996_]

We've all been there mate. K rend is great when it goes right but there's so many things that can go wrong and all the other factors. I try stay clear of it now mate and just use thin coat (JUB) so much more durable, less mess and f***king about. Good video boss like the honesty doesn't always go our way

[@jaycutts8054]

I lay it on extra thick if leaving over night and a new scratcher for every job, glad you rescued it.

[@MarkDurbin]

[@kimmason9935]

I like k rend but don't think it's the best thing to use in England especially as people don't maintain it properly it looks bad after a couple of years all the little holes get filled with dirt and it starts looking green if it's a light colour

[@gavincollins9376]

Just a jetwash every now and then works well

[@roamingnomad3054]

My husband jet washing k rend on house 2 times per year keeps it looking fresh 😊

[@kimmason9935]

Ive left it to long myself I fell your pain buddy keep up the hard work 👊

[@tobynewman6405]

In my experience on doing k rend jobs, I-bar and scratch the same day as application is aways best. I have only ever done it the following morning when it between 5c-0c over night. You should always be putting the render on early in order to finish same day, 7am start on cool days and have the render on no later than 11am. In the i-bar process you should always have 3-4mm thickness past the bead so if the render is still too soft to bar, have a long tooth scraper handy to open up the render to let it go off then you should be able to bar it off quicker. Then scratching off should be easy, using any dust that falls down to fill any holes (the dust will still be quite moist and easy to manipulate, rather than completely dry if doing it the next day) And obviously the final finish thickness should be no less than 10mm as there will be light patches throughout the finish if any thiner. The base coat should only be thin, to seal the block work and bed the mesh in

[@almusti]

Thanks for the useful info. Why does the k rend need to be scratched at the end? Surely like internal plaster it’s better to have smooth finish - uneducated guess. Thanks in advance.

[@tobynewman6405]

@@almusti k rend is a scratch finish render. Once the render is scratched it then shows the colour it is meant to be. I personally think that k rend looks miles better then sand and cement due to the slight texture and the colours are very accurate. I think some people think k rend has way more of a texture than it does, like rough cast render which you see on old cottages. Painted sand and cement can peel over time which then requires re painting.

[@almusti]

@@tobynewman6405 thanks for the reply. I was wondering if you have ever done silicone render and how does it compare to k rend? Thanks. I’ll go through your videos to see if you’ve got one. 👍🏻

[@tobynewman6405]

[@pmaconthehunt6648]

More concerned how you can see every block than anything else. Your scratcher wore down you needed a new one or several in reserve

[@darrenthebuilder]

It’s called ghosting and will disappear as blocks dry out

[@pmaconthehunt6648]

Never had ghosting before, did you do a base coat with mesh?

[@darrenthebuilder]

@pmaconthehunt6648 it can happen if the concrete block mortar hasn’t fully cured. Especially if laid in the colder weather
