By Quincey De SouzaFROM Lancashire

I contacted Smartseal Technical section with my problem that the builders had left us with (a right mess) and the Residue Remover and Limestone Sealant as recommended by Smartseal worked a treat. I cannot recommend Smartseal staff or the products enough.

Product Description

Residue Remover is a powerful ecological cleaner that unlike other acid/alkaline cleaners, does not require any neutralisation process before application.

It is specially formulated to remove surface residue and contamination from natural stone paving and other surfaces where "sweep-in" compounds may have been used.

** Disclaimer- product is designed to remove the invisible resin film left by a sweep-in jointing compound prior to sealing - NOT VISIBLE STAINS left between the joints.



  • Use neat or diluted to a 1:5 ratio depending on amount of residue present
  • Apply with either a brush or garden sprayer
  • Leave the product to penetrate and break down the surface residue (5 - 60 minutes)
  • Agitate with a stiff brush and wash off with a pressure washer
  • Re-apply if surface residue remains after first application
  • Average coverage 6 - 8 m² per litre

Product FAQs

Q: A handy man sprayed our house with a sealant for stone, unfortunately some of the sealant has sprayed on to our windows, can you suggest how we can remove this from our window.


A: It would be best to first find out what sealer your handyman had used and speak to the company regarding a remover. If you're not having any luck, you can get in touch with our technical team online or over the phone to see if there is an alternative product you can use..

Response from Sophie

Q: A joint compound has recently been used on my patio but I cannot identify any residue. Do I still need to use the Smart Seal residue remover? The patio has just been laid. Do I need to leave it a few months before sealing the patio or can I seal it whilst it looks good?


A: Ideally, allow the area a couple of months before sealing, just incase any salts breathe from the surface. The residue will not be seen as it is invisible and microscopic which will be acting as a barrier to the surface. If it has been more than six months since using the pointing compound, apply the sealer to a test area before your application as residue remover may not need to be used.

Response from George

Q: Will Residue Remover damage the sweep-in pointing?


A: No, it will be fine.
