Adheseal tips for using Everflex Supaprime
Scenario: Applying to Damp or Contaminated Substrates
Potential Outcome: Poor or failed adhesion, surface blistering, or complete delamination of the membrane or sealant, leading to critical failures and costly callbacks.
Adheseal Best Practice: All surfaces must be structurally sound, dry, clean, and free of all dust, oils, grease, curing compounds, and any other contamination. Do not apply on damp or wet substrates. This discipline is essential for a first-time-right bond.
Scenario: Applying in Wrong Environmental Conditions
Potential Outcome: Improper cure, poor penetration, or reduced adhesive performance, compromising the entire system and forcing rework.
Adheseal Best Practice: Do not apply when temperatures are below 10°C or above 35°C, or if humidity is above 85%. Always check the site conditions to ensure predictable performance and a reliable cure.
Applications in Practice: Trade Scenarios
For Waterproofers (Applicator): Priming for Membranes
The Professional's Challenge
Ensuring total, permanent adhesion of the membrane to porous concrete or screed, especially in critical wet areas, to prevent any risk of delamination.
The Adheseal Solution
Apply Supaprime at 5-10m² per litre. Use a brush, roller, or spray to ensure the entire area is completely primed. Allow approximately 60 minutes for it to become tacky, then apply the Everflex waterproof membrane over the top for a fully integrated system.
Best Practice Note
Exceptionally porous substrates may require a second coat. Use the water test first. A properly primed substrate is the non-negotiable foundation for a zero-failure waterproofing job.
For Builders & Remedial Specialists: Enhancing Sealant Bonds
The Professional's Challenge
Getting a high-strength, permanent bond for polyurethane or MS sealants on difficult, varied, or aged substrates like masonry, timber, or non-porous surfaces.
The Adheseal Solution
Use Supaprime to prime the joint. Its low viscosity penetrates and consolidates dusty surfaces and chemically bites into non-porous ones, creating a locked-in base for Adheseal Polyurethane and Hi-Flex MS sealants.
Best Practice Note
Ensure the joint surface is stable, dry, and scrupulously clean. This step removes guesswork and ensures the sealant performs to its maximum capability, preventing joint failure and callbacks.
Frequently Asked Questions
How do I apply Everflex Supaprime to concrete before waterproofing?
First, ensure the concrete is clean, dry, structurally sound, and fully cured (at least 28 days old). Apply Supaprime with a brush, roller, or spray, making sure the entire area is completely coated. It's fast-drying and should be ready for your membrane in approximately 1 hour. For very porous concrete, a second coat may be needed to ensure a perfect bond.
How do I know if my substrate is porous or non-porous for this primer?
Use the simple water test: place a dollar-sized puddle of water on the substrate. If the water absorbs into the substrate in less than two minutes, the surface is porous. If the puddle remains, the substrate is non-porous. Everflex Supaprime is formulated to provide exceptional adhesion to both types.
How long does Supaprime take to dry or cure?
Everflex Supaprime is rapid-drying. It becomes tacky and ready to be coated with a membrane or sealant in approximately 60 minutes at 23°C. You can apply coatings once it is tacky, but not wet. Always remember that site conditions like temperature, humidity, and substrate porosity will affect the final cure time.
What safety precautions and PPE are essential with Supaprime?
This is a professional-use, hazardous product and requires strict safety controls. Always use this primer outdoors or in a well-ventilated area. You must wear full PPE, including chemical-resistant gloves, eye/face protection, and, if ventilation is inadequate, appropriate respiratory protection. It is flammable, so keep it clear of all heat, sparks, and ignition sources.

Applying Everflex Supaprime: Enhanced Protocols & Best Practices
-
Step 1: Surface Preparation & Testing
Correct preparation is critical for adhesion and system success. Failure to prepare the surface correctly is the primary cause of bond failure.
Cleaning
All substrates must be structurally sound, stable, dry, and clean. Remove all dust, loose material, oils, grease, form release agents, and any other contamination.
Mechanical Preparation
If required, use mechanical methods like dry diamond grinding to create a roughened, open, and porous surface. Thoroughly vacuum all dust. Do not use solvents or acid etching.
Timing: Concrete must cure for 28 days. Sand/cement render or screeds must cure for at least 4 days.Pro Tip: Always perform the water test. Place a dollar-sized water puddle on the substrate. If it absorbs in <2 minutes, it's porous. If not, it's non-porous. This 2-minute test removes guesswork. -
Step 2: Primer Application & Curing
Apply a single, even coat to create the bond for the subsequent system. This is a hazardous, flammable liquid; ensure all safety protocols are in place.
Application
Apply by brush, roller, or spray. Ensure the entire area is completely primed with a uniform coat. Pot life is 10-15 minutes, so work in manageable sections.
Coverage
Coverage is approximately 5-10 m² per litre. This rate varies significantly based on the porosity of the substrate.
Timing: Allow the primer to dry to a tacky, translucent film. This takes approximately 1 hour at 23°C.Pro Tip: Apply membranes or sealants after the primer is tacky, but not wet. If the substrate is exceptionally porous, a second coat may be required. Do not apply if temperatures are below 10°C or above 35°C.
