Pumaflex® Pu Hybrid

Weatherproof water based polyurethane membrane.
Coating for horizontal substrates based on acrylic polymers and aliphatic polyurethane. It forms a continuous and elastic high-performance coat capable of preventing water infiltration and the resulting moisture-related issues.
Particularly suitable for preventing water ingress on terraces, flat roofs, pitched roofs, party walls, expansion joints, channels, downpipes, bituminous membranes, etc. This is generally applicable to all exterior surfaces that can be walked on, as long as this is not done on a daily or intensive basis.

Advantages and Uses

  • Rainproof.
  • Good tensile strength and high elasticity.
  • Greater mechanical strength with the use of fibreglass mesh.
  • Good homogenisation of the product and easy to apply.
  • Notable resistance to abrasion.
  • Good crack filling capability and resistance to microcracking
  • Due to its UV radiation crosslinking, it has excellent dirt resistance.
  • Very low residual tackiness of the dry film.
  • Resistant to open air and ultraviolet rays.
  • High Solar Reflectance Index (SRI) in its white version, reducing heat absorption.
  • It can be applied using a brush, roller, airless spray gun or pistole. Make sure the product has been previously mixed and correctly diluted.
  • Tools must be cleaned with abundant water before the paint dries.
  • Not suitable for permanent water contact, water storage, ponding, or significant condensation. 
  • Examples: swimming pools, tanks, ponds, cisterns, planters, etc.

Suitable Substrates

NEW SURFACES:

  • Concrete, cement, plaster, brick, stone, fibre cement, etc., must be cured, dry, firm, and free of dirt or grease.
  • Treat efflorescence or salt deposits with diluted DESMOR, rinse, and allow to dry.
  • Surfaces must be free of moss and microorganisms and should be dry or only slightly damp. 
  • In the case of cracks, holes, or flaking, repair them before applying the product.
  • Apply the paint according to the instructions given.

 

OLD SURFACES:

  • Treat efflorescence or salt deposits with diluted DESMOR, rinse, and allow to dry.
  • Remove any mould contamination using bleach or any other suitable product as well as any remaining paint or other construction materials.
  • On deteriorated substrates, those with poor cohesion, or moisture issues, apply FIJAMOR beforehand.
  • In the case of cracks, holes, or flaking, repair them before applying the product.
  • Remove sharp or cutting elements, such as damaged tiles, which could mechanically damage the membrane and replace any defective pieces.
  • The old coating should be brushed to remove loose particles, then cleaned and degreased. 
  • Apply PUMAFLEX PU HYBRID according to the instructions given.

Application Procedure

  • Shake until perfect homogenisation.
  • Dilute the primer coat by a 15% with water and spread it. Ensure thorough wetting of the entire surface, especially around the perimeter and in cracked areas.
  • Apply the second and subsequent coats undiluted, in the opposite direction of the previous one. A minimum of two coats must be applied, ensuring that the previous one is completely dry before proceeding.
  • For optimal waterproofing performance and durability, at least 1.5 L/m² of product should be used.
  • On frequently walked surfaces, a fibreglass or polyester fabric reinforcement should be placed over the first undiluted coat. – The successive sections of this reinforcement must overlap by 10 cm, ensuring that the topcoat aligns with the slope direction of the floor. The reinforcement must be stretched without wrinkles and then covered with additional coats of the waterproofing product.
  • It can be applied by brush, roll or pistole, previously shaking and diluting the product, respectively.
  • Tools must be cleaned with abundant water before the paint dries.

Recommendations

  • If sealants or asphalts are present in the expansion joints, it is recommended to properly "bridge" them with an elastic polyester reinforcement.
  • Whenever necessary, correct the slopes to prevent water ponding.
  • At junctions with vertical surfaces, reinforcement with fibreglass or another suitable material is required, applying the product up to a height of 15 cm.
  • Do not apply under 5ºC.
  • Do not apply the product with relative humidity above the 85% nor on wet substrates. Do not apply under the risk of rains.
  • Keep in fresh and dry places.
