Sika Water Seal
Sika Water Seal is a solvent based, waterproofing water seal for masonry, to protect structures against rain, damp and frost.
On application, dependent upon the porosity of the material to be treated, it penetrates to a depth of 5mm, effectively repelling driving rain. Used to protect brick, stone, concrete and masonry against rainwater penetration.
Sika Water Seal is used to protect brick, stone, concrete and masonry against rainwater penetration. It is a solvent containing clear solution and does not change the aesthetic appearance of the substrate after treatment. On application, dependent upon the porosity of the material to be treated, it penetrates to a depth of 5mm, effectively repelling driving rain. The surface however is allowed to breathe, ensuring that previously absorbed moisture will evaporate and consequently allow the treated areas to dry out normally.
This treatment is known to be effective for up to 10 years, depending upon substrate, absorbency, application rate and position.
The surface to be treated MUST be dry and ensure that masonry joints are sound and free from cracks. Apply by brush or low pressure spray at a rate of 2.5 – 4 metres / litre per coat.
Coverage will be dependent upon the porosity of the surface being treated, but 2 coats are normally applied. A trial area is recommended to establish the exact consumption. Allow 6 hours drying time between coats.

Can Sika Waterseal be overpainted? For instance, can a concrete window ledge be sealed and subsequently painted with masonry paint. Thanks
No, you could consider using a waterproof masonry paint such as Rust-Oleum Mathys Murfill Waterproofing Coating.

Can this be applied to dulux ultimate protect weathershield masonary paint.
No it cannot, it is for application to bare substrates. Assuming you require a waterproof coating, the orginal coating is in sound contdition we can recommend Rust-Oleum Mathys Murfill Waterproofing Coating.
