Out there in the Paradise known as Issan there is one Somchai who has done some work for us .
He has built up a wall at our request .
However ..... the wall looks a bit odd to me . It's made of those cheap ' cindery ' blocks and I want to have the whole wall painted in a decent paint .
But given the porous nature of the wall I do want an undercoat put on .
When they did the house they put blue paint straight onto the house render and this has flaked off .
So ......... can anyone of you more seriously knowledgeable people point me to what should be the first coat here please ?
I would imagine it needs more than a straightforward Undercoat as I suppose Undercoat is intended for indoor walls .
I need to tell this chappy EXACTLY what to go and get . As I'm not there .
Danke .
