- Kitchen walls and floors protection – Shield kitchen in food preparation areas from water damage and chemical exposure. The membrane’s resistance to oils, grease, and household chemicals ensures long-term protection in high-use environments.
- Terrace and Balcony Waterproofing – Establish weather-resistant barriers on outdoor spaces exposed to rain, snow, and temperature fluctuations. Frost-resistant formulation maintains integrity through freeze-thaw cycles while UV stability prevents degradation.
- Underfloor Heating Installations – Apply waterproofing membrane directly over heated floor structures and insulation materials without compromising thermal performance. The system’s flexibility accommodates thermal expansion while maintaining complete water barrier properties.
- Basement Waterproofing – Prevent moisture infiltration in below-grade spaces with excellent adhesion to concrete, masonry substrates, and insulation materials. The membrane’s resistance to hydrostatic pressure provides protection against groundwater seepage.
- Pipe and Fixture Transitions – Properly seal critical junctions where plumbing penetrates waterproofing barriers using specialized sleeves and tapes. These reinforcement accessories prevent water infiltration at vulnerable connection points.
- Corner and Joint Reinforcement – Strengthen areas prone to cracking with flexible corners and tapes designed for internal and external angles. The tear-resistant materials accommodate structural movement while maintaining continuous waterproofing integrity.
System Planning Guide: HydroProtect Coverage
Planning your waterproofing project requires accurate material estimation to ensure complete coverage without excess waste. FOME FLEX HYDROPROTECT membrane coverage typically yields 1.2-1.5 kg per square meter when applied in the recommended two-layer system. For standard bathroom waterproofing (15-20m²), expect to use one 15kg container or two 7-10kg containers depending on substrate conditions. Include HYDROPROTECT Primer at approximately 200-300g per square meter. Factor in reinforcement tapes for all corners and joints (typically 5-10 linear meters per bathroom), plus specialized sleeves for each pipe penetration. We recommend adding a 15% material contingency to accommodate surface irregularities.
HydroProtect Application Process
- Substrate Assessment – Verify surfaces are structurally sound, clean, and free from loose particles, dust, grease, or previous coatings. Level irregularities and defects larger than 5mm using appropriate patching compounds before proceeding.
- Primer Application – Apply HYDROPROTECT Primer to strengthen absorbent substrates and improve membrane adhesion. Use undiluted primer on low-absorbent surfaces or dilute 1:1 with water for highly absorbent substrates. Allow 4 hours drying time.
- First Membrane Layer – Mix membrane thoroughly without dilution and apply evenly using brush, roller, or steel spatula. Immediately embed reinforcement tapes, corners, and sleeves into wet membrane at all critical junctions.
- Reinforcement Integration – Press tapes and corners firmly into first membrane layer, working from center outward to eliminate bubbles. Cut tapes to appropriate lengths for continuous coverage at joints.
- Second Membrane Layer – Apply perpendicular to first layer after 2-4 hours drying time, completely covering embedded reinforcements. Maintain consistent thickness across entire surface.
- Curing Protection – Shield freshly applied membrane from rain and frost during curing. Allow minimum 24 hours before tile installation. Low temperatures and poor ventilation extend drying time.
Waterproofing with HydroProtect FAQ
What surfaces can HydroProtect waterproofing membrane be applied to?
FOME FLEX HYDROPROTECT adheres to concrete, aerated concrete, cement-lime and gypsum plaster, cement boards, gypsum boards, and sandstone. The membrane works on both new construction and existing substrates with proper surface preparation.
How many layers of waterproofing membrane are required?
Apply a minimum of two layers for effective protection. The first layer embeds reinforcement tapes and accessories, while the second layer provides complete coverage. Apply subsequent layers perpendicular to previous layers.
Can HydroProtect be used with underfloor heating systems?
Yes, FOME FLEX HYDROPROTECT is suitable for underfloor heating installations. The membrane’s flexibility accommodates thermal expansion while maintaining waterproofing integrity without interfering with heat transfer.
What is the drying time for HydroProtect membrane?
Each membrane layer dries in approximately 2-4 hours under normal conditions. Complete curing requires 24 hours before tile installation. Low temperatures and high humidity extend drying times.
Is HydroProtect suitable for outdoor applications?
Yes, FOME FLEX HYDROPROTECT performs reliably both indoors and outdoors. The membrane is frost-resistant, UV-stable, and withstands temperature fluctuations, making it ideal for balconies, terraces, and exterior wet areas. Although, it should not be the top layer – tiles should go over waterproofing.
What chemical resistance does HydroProtect offer?
The system resists hydrochloric acid 3%, sulfuric acid 35%, potassium hydroxide, lactic acid, sodium hypochlorite, and salt water. This protects surfaces from oils, grease, and cleaning products while preventing fungal and mold growth.
