Arcaclear adhesion promoter for porous surfaces





ARCACLEAR P2 - PRIMER for porous surfaces is a transparent resin used as an adhesion promoter to improve adhesion of ARACLEAR (on concrete, screed, cement, reconstituted stone, etc.).

ARCACLEAR is a high-technology waterproof membrane which is a non-yellowing, alkali and UV resistant waterproof coating with long-lasting transparency and elasticity.  ARCACLEAR is long-lasting and will protect your building materials from the elements, water ingress, freezing, pollution and acid rain.


 ARCACLEAR P2 - PRIMER for porous surfaces is used on porous building materials.  

  • cement, screed, concrete, inorganic porous materials

  • natural or reconstituted stone, brick, tiles

  • wood, travertin, anhydride screed

If your surface is non-porous (glass, linoleum, marble, travertine, etc.) see ARCACLEAR P1 - PRIMER for non-porous surfaces.       


ARCACLEAR PRIMER for porous surfaces comes in 1kg packs.  


It can be ordered alone or in a kit providing complete TRANSPARENT WATERPROOFING treatment (from priming to finish).  

The ARCACLEAR system is packaged to treat 5m² (approximately 50 square feet)  or 10m2 (approximately 100 square feet) per kit.  


Four types of kits are available depending on the frequency and quantity of foot traffic to which the surface will be subjected.

(1) no foot traffic (used over mosaics or tiling in swimming pool or on wall surfaces)

(2) rare foot traffic for maintenance purposes only

(3) frequent foot traffic within a private property

(4) frequent and heavy foot traffic in public areas

When ordering, click on the type of foot traffic to which the surface will be subjected, choose the surface area you wish to cover (5 or 10 m²), the primer adapted to your surface (porous or non porous) and the look you wish to achieve (shiny or matte).  Your kit will be composed of the components you need to cover your surface area.

Instructions for use ARCACLEAR PRIMER for porous surfaces:


Application conditions

  • Do not apply if it is raining or snowing or if rain or snow are forecast with a 48-hour delay.

  • The moisture content of the surface must not exceed 7%.  

  • For best results, the temperature during application should be between 5°C and 35°C and relative humidity should be between 50 and 70%.  

Important:  The ARCACLEAR PRIMER for porous surfaces will cure well under normal climatic conditions (5-35° C, dry weather).  
Lower temperatures will slow down curing time and higher temperatures will accelerate the curing time.  


Surface preparation

Optimum performance is achieved by using the right combination of products, surface preparation and application procedures.  Careful attention to the preparation of the surface is essential. 

  • Surfaces to be coated must be dry, clean, level, sound and free of all contaminants, loose particles, dirt and dust.

  • Surfaces with trapped moisture (under tiling for instance) must be left to dry thoroughly before application. 

  • New concrete must be left to dry at least 28 days before applying the ARCACLEAR system.


Repair Cracks and Joints before application

The careful and thorough repairing of cracks is important to ensure long-lasting waterproofing of the surface.  Clean all concrete cracks, hairline cracks, expansion joints etc.of dirt, dust and loose particles. Use a polyurethane mastic to seal.

All internal angles must be reinforced with ARCAMESH (embedded between 2 coats of ARCACLEAR). 

Do not apply ARCACLEAR PRIMER for porous surfaces on a surface which has already been treated with silane, siloxane or silicone (or other water repellent coatings) as this will have a negative impact on adhesion.  If you are not sure if your surface has been previously treated, do an adhesion test on a small surface area. 



We recommend applying a coat of ARCACLEAR P2 - PRIMER for porous surfaces before applying ARCACLEAR to obtain optimum adhesion to all surfaces except transparent plastics (polycarbonate, polyacrylate,etc.).  Apply ARCACLEAR P2 for porous surfaces with a polyester 12 mm nap roller, by brush or airless to cover the entire surface area.  Count approximately 200g per m².  

NOTE: ARCACLEAR P2 + ARCACLEAR RESIN + Arcaclear Matte Finish and Arcatraffic are available in kit form, one kit primes and waterproofs a surface area of 5m² or 10m2. 

Drying time  

2 to 6 hours.

Recoatable: 12 hours minimum, 18 hours maximum before applying ARCACLEAR.



approximately 200 gr/m2 when using a nap roller.  The coverage rate will depend on surface porosity, temperature and application method.



Can be stored in dry and cool rooms for up to 9 months.

Protect the material against moisture and direct sunlight.  Storage temperature: 5-30oC.  Products should remain in their original, unopened

containers, bearing the manufacturers name, product designation, batch number and application precaution labels.keep 1 year in original unopened packaging.
