Aquaflex Roof 77 — Best for Exposed Flat Roofs

Mapei Aquaflex Roof 77

Roof SpecialistRM90 / 4kg · RM286 / 18kg

Type: Ready-to-use acrylic liquid membrane (one-component) · Best for: Cementitious roof decks, terraces, balconies, car porch roofs, metal roofs, cupolas

No mixing required — ready to use straight from pail
UV resistant and weather resistant — permanent exposed surface
White version reflects solar heat — recommended for Malaysia's tropical climate
Apply with long-pile roller, brush, or airless spray gun
Can be applied over old bituminous membranes (with Aquaflex Primer)
Can be applied over existing ceramic tiles (with Eco Prim Grip)
Light foot traffic after 8 hours
Consumption: 0.3 kg/m² primer coat + 0.6 kg/m² per neat coat (minimum 2 neat coats)

Shelf life: 12 months — check batch date before buying

How to Apply Aquaflex Roof 77 — Step by Step

Covers concrete flat roofs and car porch slabs — the most common application in Malaysia.

1
Surface preparation
Remove all loose material, debris, moss, and lichen. Repair any cracks or voids with cement mortar and allow to cure completely. Surface must be clean and sound.
2
Apply primer coat
Dilute Aquaflex Roof 77 with 10% water (or use Eco Prim Grip for non-absorbent surfaces like old tiles or metal). Apply evenly at 0.3 kg/m² with a brush or roller. Allow to dry.
3
Treat joints and corners
Before applying the first neat coat, embed Mapeband Easy rubber tape into the wet product at all joints, corners, pipe penetrations, and parapet wall junctions. These are the highest-risk leak points.
4
First neat coat
Apply Aquaflex Roof 77 at 0.6 kg/m² using a long-pile roller. Work systematically from one end to the other. For metal roofs, apply with a brush to ensure proper surface contact.
5
Wait 2–4 hours
Allow first coat to dry completely — the colour will darken as it dries. In Malaysia's humid conditions, allow a full 4 hours. Do not apply second coat over wet first coat.
6
Second neat coat
Apply at 0.6 kg/m² in the opposite direction (perpendicular) to the first coat. This cross-hatching ensures full coverage and eliminates pinholes.
7
Protect from rain
Do not allow rain on the freshly applied membrane. Check the weather forecast — you need a minimum 8-hour rain-free window after the final coat. Schedule work for early morning in the dry season.

Pro tip: For micro-cracked concrete surfaces, embed Mapetex 50 non-woven fabric into the first coat before applying the second coat. This reinforces the membrane across hairline cracks that may widen under thermal expansion.

Aquaflex Roof 77: Pros & Cons

Pros

One-component, ready to use — no mixing errors possible
White version reflects solar radiation — measurably reduces indoor temperature
Can be applied directly over old bitumen membranes (saves demolition cost)
Can be applied over existing ceramic tiles (with Eco Prim Grip primer)
Seamless membrane — no joints = fewer leak paths
UV resistant — suitable for permanent exposed rooftop applications
Light foot traffic after just 8 hours
Available in retail pails (4kg and 18kg) — easy to buy in hardware stores

Cons

Not suitable for permanent immersion (use Planiseal series for pools and tanks)
Needs dry weather during and after application — risky in rainy season
Not suitable for areas with standing/ponding water (fix drainage first)
Cracked surfaces need Mapetex 50 reinforcement (additional material cost)
Per-kg cost is higher than cementitious alternatives (offset by ease of application)

Mapelastic AquaDefense — Quick-Dry Bathroom Membrane

Mapelastic AquaDefense

Fastest Dry TimeRM165–167 / 7.5kg · RM270 / 15kg

Type: One-component liquid rubber membrane (ready-to-use) · Best for: Bathroom floors and walls, shower cubicles, balconies, laundry rooms, wet kitchens

Tile installation possible after just 4 hours — fastest in the Mapei range
No mixing required — ready to use straight from pail
Light blue colour for easy visual coverage checking
Solvent-free, no odour — safe for indoor application
Bridges cracks up to 3.2mm without reinforcement (far exceeds EN 14891 requirements)
Adhesion 1.7 N/mm² — 3× the required EN 14891 standard of 0.5 N/mm²
Rain resistant: 1 hour after first coat, 3 hours after second coat
Full cure for flood test: 12 hours (apply tiles after 4 hours)
Works on concrete, screed, plasterboard, cement board, and existing tiles
Consumption: ~1.2 kg/m² for 2 coats (standard bathroom floor + splash zone)

Mapelastic AquaDefense Cost Calculation — Typical Malaysian Bathroom

Standard bathroom: 40 m² (floor + walls up to splash zone)

Consumption: ~1.2 kg/m² for 2 coats Total material needed: 40 × 1.2 = 48 kg

Option A — 15kg pails: 4 pails × RM270 = RM1,080 in materials Option B — 7.5kg pails: 7 pails × RM167 = RM1,169 in materials Cost per m²: approximately RM27/m²

Comparison: AquaDefense vs Planiseal 388 for the same bathroom

Mapelastic AquaDefense (48 kg): RM1,080 — tiles in 4 hours
Planiseal 388 (48 kg at 1.5 kg/m² × 2): 2 × 30kg sets = RM412 — tiles next day

Verdict: Planiseal 388 is 62% cheaper in materials. AquaDefense saves time and is no-mix — choose it when turnaround speed matters (e.g., renovation with tight timeline). Planiseal 388 is the better value choice when you have flexibility on timing.

Both are fully CE-certified and meet EN 14891 waterproofing standards. Both are suitable for floor and wall waterproofing in Malaysian bathrooms.

Which Mapei Product Should You Use? — Decision Guide

For Flat Roof / Car Porch / Terrace (Exposed to UV and rain) → Aquaflex Roof 77 (White) — UV resistant, heat reflective, ready to use, no mixing

Choose White over Grey for all Malaysian exposed roofs — reflects solar radiation, measurably reduces indoor temperature
Add Mapetex 50 reinforcement if surface has visible hairline cracks
Use Eco Prim Grip primer first if applying over old tiles or metal

For Bathroom / Shower (Before Tiling) → Mapelastic AquaDefense if turnaround speed matters — tile in 4 hours → Planiseal 388 if budget matters — RM206 vs RM270 for same bathroom coverage (62% cheaper) → Mapelastic if also waterproofing balcony or pool — multi-purpose, UV resistant, structural grade

For Swimming Pool / Water Feature → Mapelastic — 20+ years proven track record in pools, flexible, handles pool chemicals → Planiseal 388 — budget alternative with good flexibility; both are non-toxic and safe for water contact

For Underground / Basement / Retaining Wall → Planiseal 288 — designed for below-grade, resists counter-pressure up to 1 atmosphere

Cheapest Mapei option at RM106/25kg

For Water Tank / Reservoir → Planiseal 288 — specifically engineered for water storage tank lining, non-toxic when cured

Applying Over Existing Bituminous Membrane (Overlay) → Aquaflex Roof 77 — can be applied directly over old bitumen (pre-treat with Aquaflex Primer)

Extends roof life without removing existing membrane — major cost saving

For Metal / Zinc Roof → Aquaflex Roof 77 — after thorough cleaning, apply Eco Prim Grip Plus primer first

Addresses the adhesion challenge on smooth metal surfaces

Mapei Waterproofing Application Tips for Malaysian Climate

1. Best time to apply Early morning (before 10am) or late afternoon (after 3pm). Avoid peak heat — Malaysian midday surface temperatures can exceed 60°C on dark concrete roofs, causing acrylic membranes to skin over before proper penetration.

2. Plan around the rainy season Northeast monsoon: November–March on the Peninsula east coast. Southwest monsoon: April–October on the west coast (Selangor, KL). Monitor the weather forecast — you need a minimum 8-hour rain-free window after the final coat.

3. Always choose White for exposed roofs Aquaflex Roof 77 White has a solar reflectance index (SRI) that measurably reduces roof surface temperature. In Malaysia's tropical climate, this translates to 3–5°C lower indoor temperature and reduced air-conditioning load.

4. Surface preparation is 80% of success Most waterproofing failures in Malaysia are caused by poor surface prep, not product failure. Spend the time cleaning, degreasing, and repairing the substrate before opening any product pail.

5. Damp but not wet is the rule for cementitious products Mapelastic, Planiseal 388, and Planiseal 288 should be applied to a damp surface — not dry, not pooling with water. Lightly mist with water if the concrete is bone dry, especially in air-conditioned areas.

6. Storage in Malaysia's climate Keep all Mapei products in a cool, dry place below 30°C. Malaysia's heat and humidity shorten shelf life. Check the production date on the packaging — most products have a 12–18 month shelf life. Buying from stores with high turnover reduces risk.

7. Two coats is always the minimum One coat is never sufficient for any Mapei waterproofing product. The second coat — applied in the opposite direction — is what completes the membrane and eliminates pinholes.
