Prepare a wide range of surfaces for waterproofing and protective coatings with Owl Lava Primer 20. This durable two-part, water-based epoxy primer provides strong adhesion to absorbent, semi-absorbent and non-absorbent surfaces, creating a reliable foundation for the Lava 20 liquid waterproofing system.

The 4kg kit contains 3kg of Component A and 1kg of Component B, providing the correct 3:1 mixing ratio. Its low-odour, water-dilutable formulation can be applied using a brush or roller and is suitable for concrete, wood, metal, asphalt, bituminous membranes, ceramic tiles, glass and existing acrylic coatings.

Why Tradespeople Use It

• Strong Surface Adhesion: Bonds effectively to absorbent, semi-absorbent and non-absorbent substrates.
• Suitable For Damp Surfaces: Can be applied to suitably prepared damp substrates without compromising adhesion.
• Water-Based And Low Odour: Provides easier application with less odour than many traditional solvent-based primers.
• Brush Or Roller Application: Can be applied evenly using standard professional application tools.
• Vapour Barrier Performance: Can act as a Class III vapour-control barrier when applied at the specified coverage rate.
• Resistant To Standing Water: Provides a durable primed surface with strong water-pressure resistance.
• Versatile Trade Use: Suitable beneath polyurethane waterproofing systems, joint sealants and epoxy or polyurethane floor coatings.

Use it for: Priming Concrete, Polished Concrete, Wood, Metal, Asphalt, Bituminous Membranes, Ceramic Tiles, Glass, Aged Acrylic Coatings And Other Suitable Surfaces Before Applying Lava 20 Or Compatible Waterproofing And Floor Coating Systems.

Safety tip: Professional Use Only. Wear Suitable Protective Gloves, Clothing And Eye Protection And Read The Safety Data Sheet Before Use. Mix Only The Amount That Can Be Applied Within The 45–50 Minute Pot Life And Do Not Apply When The Surface Or Ambient Temperature Is Below 10°C.

FAQs

Q: What Is Included In The 4kg Kit?
The Kit Contains 3kg Of Component A And 1kg Of Component B, Providing The Correct 3:1 Mixing Ratio.

Q: How Should Lava Primer 20 Be Mixed?
Mix Components A And B Together At A 3:1 Ratio Using A Low-Speed Mechanical Stirrer For Approximately 3–5 Minutes. Make Sure The Material Around The Sides And Bottom Of The Container Is Fully Combined.

Q: Does The Mixed Primer Need To Be Diluted?
Yes. Once Components A And B Have Been Thoroughly Mixed, Add Approximately 15–25% Clean Water To Adjust The Viscosity As Required.

Q: What Surfaces Can It Be Applied To?
It Is Suitable For Concrete, Polished Concrete, Wood, Various Metals, Asphalt, Bituminous Membranes, Ceramic Tiles, Glass, Aged Acrylic Coatings And Other Suitable Prepared Surfaces.

Q: What Is The Coverage Rate?
Typical Consumption Is Approximately 0.100–0.200kg Per Square Metre When Applied In One Or Two Coats As A Primer. For Use As A Vapour-Control Barrier, Apply Approximately 0.600kg Per Square Metre Across Three Coats.

Q: Can It Be Applied To A Damp Surface?
Yes. It Can Be Applied To Suitably Prepared Damp Surfaces. For Concrete, The Moisture Content Should Not Exceed 8%.

Q: When Can Lava 20 Be Applied Over The Primer?
Lava 20 Should Normally Be Applied After 6–12 Hours, While The Primer Remains Slightly Tacky. Do Not Leave The Primer For Longer Than 24 Hours Before Overcoating.

Q: What Is The Working Time After Mixing?
The Mixed Primer Has A Pot Life Of Approximately 45–50 Minutes At 20°C And 50% Relative Humidity.

Q: How Long Does The Primer Take To Fully Cure?
Final Curing Takes Approximately Seven Days Under Normal Conditions. Lower Temperatures Can Slow The Curing Process, While Higher Temperatures Can Accelerate It.

Q: Can It Be Used As A Vapour Barrier?
Yes. When Applied At Approximately 0.600kg Per Square Metre Across Three Coats, It Can Function As A Class III Vapour-Control Barrier.

Q: Can The Primer Be Left Exposed?
Lava Primer 20 Is Designed To Be Overcoated With A Compatible Waterproofing, Sealant Or Floor Coating System. The Primer May Yellow Or Fade When Exposed To Ultraviolet Light.
