Product Overview
What is Zahabiya Water Shield ZSAC-10/55?
Zahabiya Water Shield ZSAC-10/55 is a ready-to-use, low VOC, acrylic elastomer-based liquid waterproofing membrane and sealing system. It works at every stage of construction, from below-ground basements and plinths up to exposed concrete roofs, roof gardens and metal sheet roofing.
Once cured, the coating forms a seamless, highly elastic membrane that stretches with the building as it expands and contracts in the Nairobi sun and rain. It bridges hairline cracks, seals joints and laps, and stays flexible without cracking or peeling.
The membrane resists water, oil and salts, which makes it well suited to saline and waterlogged areas. It is non-toxic, non-corrosive and fungus resistant, so it can be used inside drinking water tanks and reservoirs. The bright white finish reflects sunlight and lowers heat build-up on roofs and slabs.

Application Guide
How to Apply Zahabiya Water Shield
First CoatDilute with 20% clean water. Primes and penetrates the surface.
Second CoatDilute with 10% clean water. Builds the membrane body.
Third CoatApply as supplied, undiluted. Seals and finishes the surface.
Prepare the Surface
Sweep off dust, loose plaster, moss and old flaking paint. Scrape rust from metal sheets. The surface should be sound, clean and free of grease or oil.
Repair Cracks and Joints
Open up wide cracks and fill them with a suitable repair mortar or sealant. Fill ponding spots on flat roofs so water drains away.
Dampen Porous Surfaces
Lightly wet very dry or hot concrete before priming so it does not suck the water out of the coating. Remove any standing water.
Mix and Apply the First Coat
Stir the pail well. Mix the first coat with 20% clean water and brush it firmly into the surface, working it into pores and corners.
Apply the Second Coat
When the first coat is dry to touch, apply the second coat thinned with 10% water, brushing across the direction of the first coat.
Apply the Third Coat
When the second coat is dry, apply the third coat undiluted for full film thickness. Give extra attention to edges, upstands, outlets and pipe penetrations.
Let It Cure
Allow the membrane to cure for at least 3 days before foot traffic, tiling over, or filling a tank. Protect it from rain during the first hours after application.
Tip: for joints, wall-to-slab corners and cracks that keep moving, embed a strip of polyester fabric or fibre mesh into the wet second coat, then cover it with the third coat for extra crack bridging.
Do
- Apply in dry weather, ideally in the morning or late afternoon
- Keep the pail closed between coats
- Wash brushes with water straight after use
- Rinse tanks with clean water before first use
Avoid
- Applying when rain is expected within a few hours
- Coating over standing water, dust or oily patches
- One thick coat instead of the three-coat system
- Storing the pail in direct sun
Questions
Frequently Asked Questions
Can Water Shield be used on a leaking iron sheet or asbestos roof?
Yes. Water Shield bonds to concrete, asbestos, FRP and metal roofing sheets. Clean off rust and loose material first, then apply the three-coat system, paying extra attention to screw heads, laps and ridges.
Is Water Shield safe for drinking water tanks?
Water Shield is non-toxic and suitable for drinking water applications. Let the final coat cure fully for at least 3 days and rinse the tank before filling.
Can I tile over Water Shield in a bathroom?
Yes. Once the membrane has cured, tiles can be fixed with a good quality tile adhesive. Ask our branch staff for a compatible adhesive.
Can I paint over it or use it as an exterior wall paint?
Water Shield can be used on exterior walls as a waterproof coating. If you want a different colour, ask at either branch about available shades.
