Ok - I'm doing something wrong but what? This is really frustrating and beginning to tick me off.
I recently damp proofed an "old" section of the garage that worked out really well - see....
However the floor was a bit of a problem. All worked out well in the end but only after some backbreaking hours.
I used a Cement Based Leveling Compound/SBR mixture. Evidently the SBR makes the mixture waterproof, more workable, flexible and stronger. The problem I had was bubbles in the mixture when laid. These popped and left craters in the finished surface. I'm not talking about the odd one here and there... It was literally covered! see...
This was put down to over entheusiastic mixing with one of these...
I spent hours down on my knees filling each hole by hand.
So when I came to next section I decided to mix by hand. Small shovel in a builders tug...
Guess what - exacly the same - bubbles and craters. More hours kneeling/filling... Hmmm...
More discussion with the vendor of the stuff..
Ok - do the mixing then let it settle in the tug for a while... also buy a spiked roller from a builders merchant and use that--- then you'll be ok...
Well none of the builders merchants had a clue about a spiked roller... But I managed to buy one from here...
See picture here...
I have just done one further bag on the next section... mixture left to settle, then pour, spread with trowel. As bubbles start to appear splat them with the roller... Great - but hang on.. they re-appear... In fact the roller seem to have just about zero effect...
Is there an expert out there that can tell me what I'm doing wrong!!!!!! Please!!!
