UltraTech Seal & Dry ILW+
Integral waterproofing liquid admixture for plaster, mortar and concrete
Product Overview
UltraTech Seal & Dry ILW+ is a specially formulated integral waterproofing liquid that is mixed directly into concrete and mortar to make the matrix water-resistant from within. By improving cohesiveness and workability at a reduced water-cement ratio, it enhances yield, compressive strength and overall water tightness, reducing the capillary movement of water through plaster, slabs and structural elements. The liquid blends easily, leaves no residue and works across a range of cement types. It is engineered for both new construction and renovation where built-in protection against dampness and seepage is required. Part of the UltraTech Building Products range, it is available through Space Arc Engineering, an Authorized Project Distributor in India, with technical guidance on correct dosage for plaster, mortar and concrete applications.
Features & Benefits
- Integral protection: waterproofs concrete and mortar from within rather than just at the surface
- Improves workability and cohesiveness even at a lower water-cement ratio
- Enhances compressive strength, yield and water tightness of the mix
- Reduces shrinkage cracks and capillary water movement through plaster and concrete
- Easy single-pot dosing that blends uniformly without lumping or residue
- Conforms to IS 2645:2003 and IS 9103:2000 for assured quality

Frequently Asked Questions
What is UltraTech Seal & Dry ILW+ used for?
It is an integral liquid waterproofing admixture added directly to concrete and mortar to improve cohesiveness, workability and water tightness. It is used in plaster, RCC slabs, beams, columns, basements and masonry mortar to reduce seepage and dampness from within the mix.
What is the correct dosage of Seal & Dry ILW+?
The recommended dosage is 200-300 ml per 50 kg bag of cement, depending on the cement type and mix design. It is added into the gauging water and mixed for 2-3 minutes. For higher dosages, the mix should be tested for cohesiveness, workability and strength. Always refer to the product TDS.
Does Seal & Dry ILW+ conform to any IS standard?
Yes. UltraTech Seal & Dry ILW+ conforms to IS 2645:2003 (integral waterproofing compounds) and IS 9103:2000 (concrete admixtures), giving engineers confidence in its quality and performance.
