Resiblock

[Marsoupial]

Hi, I have 25l of resiblock paving sealer which is unopened and has been stored in my garage for quite some time. Unfortunately I just never got round to using it and I was planning on washing down the drive and sealing it now. However I have just noticed it is 5 months past the manufactures shelf life(18months). Do you think this will still be ok to use? In an ideal world I would bin it and buy some new but it’s quite expensive stuff!
Any advice of guidance would be greatly appreciated thanks

I have never used that make of sealer before so cannot guarantee my answer but it is a solvent based sealer the same as the acrylic sealer I use & that never goes off. There may be a possibility of yours going off if the tin is only part full & the solvent can evaporate thus making the sealer more concentrated & probably too quick drying
