questions Ron Killick on 23/10/2018
Question: 

Can Sika 1 Waterproofer Liquid Admixture simply be painted onto a damp wall/floor and seal them against moisture transfer. This is for a garage so does not have to be absolutely waterproof just help reduce ingress. Thanks

No, something such as Sika Damp-proofing Slurry may be more suited to your application.
