How do i get mortar film off


We layed our patio pavers and broomed in mortar.We washed and scrubed all of it off but when it dries there is a white film left. We already planned to seal the pavers to give it a darker look and now this.Im worried about cleaning it with acid i just dont want to lightin the pavers at all.

I don't know why you would broom in mortar, over pavers. The surface of these are filled with crevices.
Who told you to do this? The mortar will have absolutely no holding power going into tiny spaces between the pavers.
I don't know if even acid will do the trick.

I do not know if acid would do it but if you try acid test it on one or two pavers before doing the entire patio. You might have better sucess with a very powerfus pressure washer if you can use it without washing out the base. As mentioned in the post above mortar is not very effective holding the pavers in place. Sharp sand or crushed stone is very effective keeping everything in place. My preference is crushed limestone if I can get it. The sharp angles and different sized grains are what does the job. If it were me, at this point I would leave the mortar in place and use the sharp sand or crushed stone as it washes away.

You might try some of the sealer right on the pavers as they are. It may darken the mortar and make it less noticeable. I am not big on sealers for pavers because you need to reapply it every year or two.

If you are talking about interlocking concrete pavers, you NEVER put motar in the joints. You sweep and vibrate masons sand into joints as you get the final surface even with a vibrator.

Could you have been using polymeric sand? This can cause noticeable films depending on the weather and paver color.
