painting a parge coat

[mjc55]

We are building a Pod where we will live on site whilst building the house.

 

We don’t want to finish the internal walls (plasterboard probably) of the Pod yet as this is a task for when we can move into the house and rearrange the Pod (to include a store room with external access)

 

This is an Ecobrick build - we are mimicking the main house so that we can potentially sort out any issues before the main build,

 

I was wondering what would be best for "painting" the parged walls to a) lighten them  and b) reduce the roughness.

 

Any suggestions welcome as what makes sense to use as a short term (no more than a year hopefully) solution.

Our walls are Durisol (pre Ecobrix), we parge coated with a cement, lime, building sand. Mixed with water to a double cream consistency. Then applied with a broom. It fills all the holes in the block and all joints. Wall becomes airtight after. Should last for ever. If want any colour other than grey paint it after.

Thanks for that but we have already applied the parge coat.

 

The question is about what to paint with as a temporary - but I would expect to be in the pod at least 9 months so want something other than the grey parge coat finish.

Masonry paint or emulsion.

 

Try on a small area, make sure it stays put before you commit.

Lime wash. Make your own if you wish with 'bag-lime' (hydrated lime from mainstream merchants)
