Preparing concrete floor repair holes, then self levelling whole floor

MissBuilding1975 · 22 Jan 2018

Hi everyone,

I am having a bit of a nightmare removing all dust from my concrete floor surface because the floor is bumpy I can't hoover. Below is pictures, I need to patch up the holes first before applying the self levelling compound. Please could anyone help me regarding the following below.

1. Is it essential that I remove all dust from the surface? Is there any other way of doing this quickly, tried broom etc..

2. Should I seal the holes before applying the concrete? Like a pva mix or should I buy one of them adhesive sticky liquids which mixes into the concrete mix and apply that directly to the hole (if so then could you recommend me what liquid I should get) , bearing in mind the floor is still dusty? Your thoughts on this please. What state should the hole be in before applying the concrete back?

This goes for the whole floor too, when I then put the self-levelling compound on.

Thanks in advance for your response.

Thanks again.
