Rendering a wall in fall 1st coat of sand cement render applied, base coat know as a scratch coat, in winter time and giving many of details and advice IF YOU WATCH THIS VIDEO 100 TIMES IT MIGHT HELP AND MAKE YOU BE ABLE TO PLASTER BUT ONE THING I CAN GURANTEE IS IT WONT MAKE YOU A WORSE PLASTERER A few tips from me for cold winter fall whether working with exterior renders of most types that I tend to abide by which helps me run my day rather than the day running me!
We’ve all been there, waiting in a cold van, with cold feet waiting to rub up and finish, lights on at 6pm to 8pm when the sun goes down and the dreading newspaper on the soggy bottoms!
Rendering in cold conditions for me is about effective decision making with the choice of render, choice of mix, choice of prep work and choice of additives if any. There are multiple combinations out there and just because the temperatures drop doesn’t mean you can’t render in sub zero temps or very high temps in the summer. I see guys even out in India Australia Spain doing cement renders in 37degree heat and getting great results Canada Russia doing cement and polymer renders and plasters in temps as low as minus 5 but tend not to when it gets below that.

Things that work for me in the cold

Traditional cement renders:
1. Leaving the gear open for longer so water can evaporate instead of all dropping to give a soggy bottom because you’ve sealed the background and hit the top coat with a spat or trowel to close it.
2. Use suction to your advantage so little or no waterproofer in you scratch and use hydration on the cured scratch or background to win your day.
3. Use more suction and key rather than relying on a bond for adhesion.
4. If you substitute plasticiser for a shovel of lime then your set will be increased so a little there to think about
5. On blockwork don’t seal the life out of them unless you really have to
6. Cavity wall or solid wall? Is the heating on? Is the radiator on that wall blasting away which can effect coloured render scrapes if it’s of solid wall construction. Is the house empty and cold? Sun on that elevation during the morning/ afternoon. These can play an advantage in your decision making.
7. Use of accelerators, calcium chloride flakes (providing no metal is in the system), rapid hardener and frost proofer can all play a part in winning your day when used and gauged correctly.
8.working with the wind and the sun trying to use weather to an advance if possible
9. Gutters make sure there is guttering if no make sure to pipe or divert rain water away from walls to keep them as dry as possible both before rendering and after #rendering #winter #fall rendering a great render job should start with the 1st coat, base coat called a scratch coat a mix of sand and cement on this video we talk in depth about sand and cement render and scratch coating the block wall loads of advice and tips giving in the how to scratch coat render video.
