Description:

RAINCOTE is a high performance colourless penetrating water repellent specifically formulated for above grade masonry surfaces. Applied to the exterior surface of a wall RAINCOTE effectively prevents the entrance of moisture, even from high velocity wind driven rain. RAINCOTE provides economical protection for buildings, bridges, silos and other masonry structures as well as other porous substrates such as fibrous cement roofing.

Composition:

RAINCOTE water repellents are based on a composition of active waterproofing ingredients dispensed in a blend or aromatic solvents. When applied in accordance with the manufacturer's recommendations RAINCOTE will penetrate up to 13mm into the substrate, depending on surface porosity. RAINCOTE does not contain silicones, oils or varnishes.

Advantages:

RAINCOTE in essence becomes an invisible raincoat and will not discolour the surface. Preserves original beauty and prohibits discolouration. Penetrates deeply, extending the life of the masonry. Permits masonry to "breathe" -disallows the entrance of water as a liquid, yet permits moisture in a wall to escape as a vapour. Leaves no film on the surface. Excellent resistance to ultra violet rays of the sun. Forms a barrier against water penetration. Substantially retards cracking and crazing in stucco, concrete, masonry and similar surfaces when properly applied to cured substrates.

Surface Preparation:

Correct surface preparation for any applied finish is of paramount importance for the treatment to be successful.

1. repair all cracks and re-point faulty joints. All voids and defective masonry must be patched.
2. The surface must be free of laitance, dirt, fungi, algae, moss and other contaminants which will prevent penetration of the sealer.
3. Efflorescence and most stains can be removed by using a 10 % solution of hydrochloric acid followed by vigorous washing.
4. All surfaces must be completely dry before application. Avoid applying RAINCOTE if rain is imminent.

Application:

The use of non-fogging spraying equipment is the recommended method for applying RAINCOTE. Airless spray units are most preferable however, hand pump or knapsack type sprayers capable of providing and even continuous spray pattern are acceptable alternatives. When using airless equipment use the lowest practical pressure. Flood the surface by applying a liberal coating. Keep the spray nozzle between 100mm - 150mm from the surface and allow the product to run down over the surface. On masonry surfaces with average porosity a 200mm run down of product should indicate the substrate is being flooded.

Coverage:

Coverage and penetration will vary with different surfaces. The following table will act as a guide:

Precautions:

Surfaces must be dry. Not for use below grade. Use only in well ventilated areas. the solvents in RAINCOTE are flammable and will soften bitumen or asphalt based coatings. Protect shrubs and plant life from overspray.
