Polar Acid Etch Primer Solution - 5 Litres - For Preparing Concrete & Stone Floors - Interior & Exterior Use - Etches Alkaline Surface Providing Key Prior To Painting - Cleans Dirt, Oil & Stains

This is a good product supplied at a good price as well as excellent delivery. A little expensive for what it is but Would buy again.

First ever review. Complete waste of time and didn’t froth once. Might as well of just dropped gloopy soap onto the surface. Terrible, sorry. Stay clear.

This is a strong Acid, a detergent and an indicating dye that reacts to acidity levels keeping pink, when the concrete or bricks react to the acid this alkali reaction reduces acidity and hence colour goes clear. A useful indicator to guage how much reaction gas occured and hence cleaning effectiveness of this Polar Acid Etch. I used a stiff yard brush to carefully rub this onto the concrete patio. I used PPE in the form of overalls, strong wellingtons, gloves and safety glasses. Actually a good idea as the Polar Acid Etch damaged my safety training shoes - so this PPE is not over zealous at all. I waited for the colour change after all the fizxing/frothing and then used the stiff brush again and a gentle hose pipe deluge. Results amazing and coverage 20m2. The time to go clesr was about 20 minutes. The patio looked like new, if not slightly bleached. But amazingly clean and all algae gone. The stain i made cleaning the petrol lawnmower gone and the very odd plant pot stain gone completely. Amazing product i will definately use again and highly recommend, Andrew

This can be used on interior and exterior concrete surfaces.It cleans and protects and removes cement particles that maybe loose.No need to dilute simply brush on and scrub leave for 15 mins and allow to dry.Clean all equipment.The pink gel with froth this is it reacting and then it go clear.It will clean oil and dirt stains .

I ordered this hoping that it would clean up some rather nasty looking oil stains that were left from an old car of mine some years ago and up until now nothing I have tried will clean it.This product comes in a large five litre container ready to open and pour onto the surfaces leading cleaning, I started by splashing some of this liquid all around the staining and then using a stiff garden broom I rubbed it in as best as I could. Almost instantly I could see the darkness of the stains coming loose so I added some more of this product and then left it to work for about thirty minutes. After a nice cup of tea I once again rubbed it in with the broom and finally rinsed it away.What I was left with was almost like an acid bleached area and it was a little lighter than even the clean parts of my driveway. This had removed the stains that nothing else had worked on but the downside is that to give the drive a better look I will need to do the same again on the entire driveway, so more work for me, lol.I don't intend to paint my drive but I can see that this solution will prepare a concreted surface ready for painting with relative ease.Excellent cleaner.Recommended.

I have used this solution to clean my driveway. The driveway is 6m x 8m. I have not washed it for the last couple of years, and there was so much grime, oil stains etc., on it. Therefore I have used all of the canister of the solution. Spread it all over and brush it with a still garden brush. Ste solution started to foam. After 10 min, gently wash it away with a pressure washer. I did not have to power wash it very hard or brush it with vigour. It has removed the majority of grime, dirt and even oil stains. It was very easy to clean away and left remarkable results. I am impressed. One small area was left without a solution for a test, and that are had to be pressure washed hard, in order to be cleaned.

Big bottle of acid cleaner to use before painting or just to refresh concrete/ stone surface.It does exactly what it says on the bottle. Comes in a form of pink gel. Very easy to use- just brush on the surface, damp if necessary, wait for magic to work and rinse. 1 litre of product should cover about 4sq meters. 5 litre bottle was just enough to clean my drive.

So the description states this is a:-Acid etch primer solution. 5 litres for preparing concrete & stone floors. Interior & exterior use, etches alkaline surface providing key prior to painting. Cleans dirt, oil & stains.This is what I was told I needed to clean the concrete flooring in the back garden. This acid cleans the floor and I think it's like what you do befor you paint wood, you would use sandpaper on the wood to make a key, like little marks and scratches to help adhere the finishing paint.We had a really lovely warm weekend so I wanted to try a test patch first, which I did and worked.But then...The weather turned to snow. So I have a test patch done and I'm already impressed, can't wait to carry out the rest when the weather is better.I always use a mask and gloves useing any treatment.
