yes, primer and undercoat are the same thing - you need to ask the DIY shopkeeper, undercoat for wall or metal - the purpose is that the paint will last longer (only can answer tis for u, cos recently painted my own place)

To apply puttyfilla for levelling uneven wall, better use trowel or scraper?
After apply, when sanding it, how rough the sand paper to use? What is the difference between puttyfilla and skim coat? Which one is better in term of durability, economical, ease of use and final result? |

maybe people i employed last time sucks, i am very satisfied with my diy on my wall yesterday. i could say way better.
i think it is worth to diy because we can put more effort than them, we pay attention to our work and do it for perfection instead of those who do it just for money. price is to consider, so are the quality. |

For skim coat, there are powder type and ready mixed type.
The powder type we need to add water ourself. Use which one better? |
