My question is stupid, but..
Is there any wall paint (water based emulsion) sealant that is not changing the colour (at least a lot).
We have painted our house walls in light grey "dullux once' paint, as we could not find this shade locally in "easy care". We also have been in a hurry. But now I think it will become dirty to soon, as the finish is very chalky and dirt attractive.
So is there any product to use afterwards, if anyone knows please
