Tips Please on How to Plaster/Render Blockwork Gate-Post

[roiseal]

Hi there. The gate posts to my drive are made out of block and have never been treated or weather-protected. They are 5 blocks high and 1 block wide and the previous owner (who built the house) filled them with concrete.

I would like to smarten them up from the dull grey block but before painting them what should I do to the surface. I don't even know the correct term - do they need some exterior plaster or render applying? And what is the best product to use?

Cheers in advance for any advice.

Render is the term you are after.

It is usually mixed yourself - predominantly sand and cement and done in two coats.

For each coat, the pros on here could advise better ratios of cement/sand and what additives (waterproofer, plasticiser etc) to add. It is also important on the type of sand used.
If you search the forum on render, I'm sure you'll get some useful posts.

Good luck.

Do you have any coping stone or capping on them - you will need something with a drip on top so that your render will last longer
