Dr. Fixit 112 Pidifin 2K – Acrylic Cementitious Waterproof Coating
Dr. Fixit 112 Pidifin 2K – Acrylic Cementitious Waterproof Coating
Flexible two-component waterproofing for bathrooms, kitchens, balconies, terraces, concrete canopies and water tanks. Made in Kenya by Pidilite East Africa, available at Shabbiri Hardware on Magadi Road.
Product Overview
Dr. Fixit 112 Pidifin 2K is a two-component waterproof coating made from a liquid acrylic polymer and a specially blended cementitious powder. Once mixed and applied, it cures into a tough, elastomeric membrane that bonds firmly to concrete and masonry, stops water from passing through, and stretches with the substrate so hairline cracks do not reopen leaks.
It is the go-to waterproofing coating for wet areas such as bathrooms, showers, toilets and kitchens, as well as exposed areas like balconies, terraces, canopies and planters. Contractors and homeowners across Nairobi, Ongata Rongai, Kitengela and Kajiado choose it because it is easy to mix, brush-applied, and can be covered with tiles or screed once cured.

How to Use Dr. Fixit Pidifin 2K
Surface Preparation
- Clean the surface mechanically (wire brush or grinder) to remove loose particles, laitance, grease, old paint and dust, then wash with water.
- Fill cracks and crevices with a polymer modified mortar (PMM) made with Dr. Fixit Pidicrete URP, Super Latex or Pidicrete MPB.
- Form coving (fillets) at wall–floor junctions and seal pipe outlets before coating.
Pre-wet the Surface
- Wet the surface thoroughly with water and let it reach a touch-dry state – damp but with no standing water.
Mixing
- Shake the liquid can well until it is a uniform milky colour, then pour it all into a clean mixing bucket.
- Slowly add the powder while stirring continuously with a slow-speed drill and paddle.
- Mix until you get a smooth, lump-free slurry. Mix only what you can apply in one session.
First Coat
- Apply with a stiff nylon brush, working the slurry well into the surface so all small undulations are filled.
- Carry the coating about 300 mm up the walls in wet areas and around pipe inserts.
Second Coat
- Once the first coat has set (within the 6 – 8 hour window), brush on the second coat in a direction perpendicular to the first for even, pinhole-free coverage.
Curing & Protection
- Leave the coating to air cure for two days. Do not water-cure.
- Protect from direct sun with a moist hessian cloth kept above the surface.
- In bathrooms, terraces and open balconies, cover with screed or tiles after curing.
Pro Tips for a Leak-Free Job
- Never add water to the mix – use only the liquid component supplied.
- Do not apply in rain or when rain is expected within 24 hours.
- Do a water ponding test in bathrooms and balconies before tiling.
- Embed a fibre mesh in the first coat at corners, joints and cracks for extra strength.
- Wash tools with water immediately after use.
