AlkaSeal can be applied by spray or roller. Application of the first and possibly the second coat should be carried out on falling temperature to aviod the possibility of bubbling from air escape from the substrate and to maximise pentration. Premature exposure to moisture from the substrate or atmosphere may result in whiteneing/clouding of the finished product. A trial area is recommended before proceeding. Apply evenly and aviod leaving any excess product on the surface. As Alkaseal is a thin coating, all imperfections will be reflected throught the coating.

Clean immediately using solvent. Hardened product can only be removed mechanically.
