Sikalite® AE Powdered Waterproofing Admixture for Mortar & Concrete
Ready-to-use powdered waterproofing admixture for cement/sand mortars and concrete. Provides waterproof structural concrete and cement/sand mortars, screeds, and renders for walls, facades, floor toppings, and jointing mortars. Suitable for use in hot and tropical climatic conditions.
Sikalite® AE is not applied as a coating — it is batched as a dry powder directly into the cement/sand mortar or concrete mix at the mixing stage, imparting waterproofing properties to the entire cured matrix from within.
Formulated for hot and tropical climatic conditions — the AE designation confirms suitability for UAE's 45°C+ ambient temperatures and coastal salt-laden environments. Enhances the waterproofing and durability of concrete and mortar mixes used across Dubai, Abu Dhabi, Sharjah, and Ras Al Khaimah — including those subject to saline groundwater, high humidity, and aggressive coastal exposure.

What is Sikalite® AE?
Sikalite® AE is a ready-to-use powdered waterproofing admixture for cement/sand mortars and concrete. It is batched directly into the mix at the mixing stage, imparting waterproofing properties to the entire hardened mortar or concrete matrix from within — rather than relying on a surface-applied coating that can be damaged, worn, or delaminated over time.
When added to mortar or concrete, Sikalite® AE reacts with the cement hydration products to reduce the permeability of the cured mix, producing a denser, more watertight matrix with improved resistance to water ingress. It is suitable for hot and tropical climatic conditions — the AE designation confirms formulation for UAE and Gulf region environments.
Typical Applications
Key Performance Benefits
- Integral waterproofing — imparts waterproofing to the full depth of the mortar or concrete matrix
- Ready-to-use powder — simply batch by weight into the mix at the drum or mixer
- Suitable for cement/sand mortars, concrete, screeds, renders, and jointing mortars
- Hot and tropical climate rated — AE designation for UAE and Gulf region site conditions
- Reduces permeability and water absorption of the cured mortar or concrete
- Durable performance — waterproofing is within the matrix, not dependent on a surface coating
- Beige powder — minimal visible impact on the colour of the finished mortar or concrete
- Easy dosing — weighed in at the mixing stage with standard site batching
Pour Part A liquid into a clean container. Gradually add Part B powder while mixing using a slow-speed drill with paddle mixer. Mix until a uniform, lump-free slurry is obtained. Use the full pre-measured kit — do not split partial packs unless quantities are weighed accurately.

Application Guide — UAE Site Conditions
Follow these steps for effective use of Sikalite® AE as a waterproofing admixture in cement/sand mortars and concrete under UAE's hot, coastal, and high-humidity site conditions.
Determine Dosage
Consult the Sikalite® AE Technical Data Sheet for the recommended dosage by weight of cement for your specific mix type — mortar, screed, render, or concrete. Dosage varies by application and desired waterproofing level. Weigh the Sikalite® AE powder accurately using site scales — do not estimate by volume. Record the dosage used for QA/QC compliance on UAE projects requiring mix documentation.
Batching into the Mix
Add the weighed Sikalite® AE powder to the dry cement and aggregate at the beginning of mixing — before adding the gauging water. This ensures the admixture is evenly distributed throughout the dry mix before hydration begins. Mix in the normal way for the mortar or concrete type being produced. Do not add Sikalite® AE to a mix that already contains gauging water, as this may result in uneven distribution.
Mixing & Workability
Mix to the standard duration and speed for the mortar or concrete type. Sikalite® AE will be uniformly distributed throughout the mix once the normal mixing cycle is complete. The workability of the mortar or concrete may be slightly modified by the admixture — adjust gauging water within the limits of the approved water/cement ratio to achieve the target consistency. Do not over-water the mix to compensate for stiffening.
Application of Mortar or Concrete
Place, compact, and finish the mortar or concrete in the normal way for the application type. For screeds, compact thoroughly to eliminate voids and achieve a dense, uniform surface. For renders, apply in layers of appropriate thickness and finish to the specified surface texture. For concrete, compact fully using internal vibrators to eliminate honeycombing — the waterproofing benefit of Sikalite® AE is dependent on a dense, well-compacted concrete matrix.
Curing
Cure the mortar or concrete in accordance with standard good practice and the project specification. In UAE hot weather, curing is critical — inadequately cured concrete or mortar will lose strength and watertightness regardless of the admixture used. Apply wet hessian, polythene sheeting, or a compatible curing compound immediately after finishing and maintain for the full specified curing period.
Not a Coating
Sikalite® AE is a mix admixture — it must be batched into the mortar or concrete during mixing. It is not applied as a surface coating and cannot be brushed or trowelled onto a hardened substrate as a waterproofing layer.
Accurate Dosing
Always weigh Sikalite® AE accurately — do not estimate by volume or add by approximation. Over-dosing or under-dosing affects both the waterproofing performance and the mortar/concrete mix properties. Record dosage for QA documentation.
Curing Essential
Adequate curing is critical to achieve the full waterproofing benefit. Poorly cured mortar or concrete will not develop the dense microstructure needed for effective water resistance — regardless of admixture dosage. This is especially critical in UAE's hot, drying climate.
