patching render ???

[Nath456]

hi i have a job on thursday which i have to patch in smooth render there are a few patchs, one about 1m2 and a few more smaller then that. i have never done any rendering before ?? but i thought that this would be a great job to start. i thought i could put rapid cement in the scratch coat at 4 - 1 and top the same say with 5-1 ? im not sure about waterproofer ?? or febmix ?? it would be a great help if you could help guys. by saying how u would do the job and what method thanks guys

Weber OCR i'd use on patchs like this......

Yes, Weber ocr would be good. Not too hard or soft. Try insulation stockist rather than a builders merchant for it. If its thin you may get away with it in one day. If its thick then cheat a bit by using a frostproofer to accelerate or do it over two days

i have never used this stuff before but i have read up on it and it says its a one coat rend ?? but rigsby said i might get away it in one day? do i need give it a scratch coat then ? if i use the frostproofer how much do i put in ? and how much time will i have i to play with it ? do you guys use ur drill to knock it up or a mixer? how should i prep before if its back to brick ? thanks guys you have great help

If it's not to thick i'd just lay it on in one coat, or 2 passes in same day if a bit thicker.

Just mix it up in your grollia tub with your drill....

I did a porch to day built in 3.5n block. 10mm beads, 5mm scratch coat then turn back and put the second coat on. Done for 2.30pm. Sometimes putting it on in 1 coat can give you uneven suction so I prefer 2 coats so the second coat is more manageable.

I mixed it in a belle mixer and it was fine but it is best mixed with a whisk. No accelerator today but if you do use one start with 1 ltr per mixer full. I start first thing with 1 litre and increase it to 2 ltrs pro rota as I approach 12pm or am I never which one but noon anyway.
