TREDGRIP FAQ

WHAT IS TREDGRIP ?

Tredgrip is a styrene acrylic copolymer which has high elasticity and tensile strength with the addition of a partly crosslinked crumbed rubber which acts as a non skid medium in the high solids solution. Solids content is in excess of 65% which yields a coating of high covering power, excellent weathering ability and high resistance to pollutants, acids and alkalis.

WHAT SURFACES CAN IT BE APPLIED TO ?

Tredgrip can be applied to most substrate types very successfully. These include concrete, timber, steel, aluminum, fibreglass and Butynol

Concrete: We strongly recommend concrete to be acid etched with dilute spirits of salts, flushed with plenty of clean water and allowed to dry. If the surface is smooth or powdery, we strongly recommend the use of a thin primer prior to the application of Tredgrip. Once the primer has dried (approx 15 ‑ 20 minutes) three coats of Tredgrip should be applied according to the directions on the can.

Timber: In most instances, Tredgrip can be applied directly onto timber according to the direction on the back of the can. If however the timber has been exposed to weather for a period and has signs of cracking we strongly recommend the use of an acrylic timber primer prior to the application of Tredgrip. A primer should also be used in areas of either high trafficking or possible abuse e.g a ramp or deck at a school etc.

Steel: If the steel is clean and free of loose rust Tredgrip may be applied to steel directly with excellent results. If however rust is present and difficult to remove completely we recommend the use of Ferronite Primer in accordance with the manufacturers directions, then apply 3 coats of Tredgrip in accordance with the directions on the can.

Aluminium: Ensure that aluminium is free of grease and oil and apply Tredgrip in accordance with the directions. If the surface has been subject to fuel or marine oil contaminates or excessive or continual salt spray, fastidious attention to cleanliness is essential for total adhesion. If there is any doubt at all an etch primer should be used prior to the application of Tredgrip.

Fibreglass: Using a coarse tough sanding block or disc, lightly abrade the fibreglass surface and dust off ensuring the surface is free of sanding dust. Apply Tredgrip in accordance with the directions on the back of the can.

Butynol: Ensure the Butynol surface is clean and dry and apply 2 or 3 full bodied coats (depending on service requirement) straight from the can in accordance with application directions.

TREDGRIP SHOULD NOT BE APPLIED INTO BATHS, SHOWERS, THE INSIDE OF SWIMMING POOLS OR ANY AREA WHERE IT MAY BE SUBJECT TO TOTAL WATER IMMERSION

IS TREDGRIP RESISTANT TO SALT WATER ?

Because of the genetic nature of Tredgrip it is extremely resistant to salt water and weathering. If however Tredgrip is to be top coated for maintenance or repair, flush the area with plenty of clean water to eradicate any trace of salt build up which may impair adhesion.

IS TREDGRIP RESISTANT TO ACIDS & ALKALIS ?

Yes, again because of its genetic make up Tredgrip is resistant to a wide range of chemicals including nitric acid, phosphoric acid, sulphuric acid, acetic acid, sodium hydroxide, ammonia, oils, alcohols, most solvents and petroleum products.

HOW LONG WILL TREDGRIP LAST ?

This is largely dependent on the type of service it is subject to, but if it is applied in accordance with our recommendations it would be reasonable to expect from 5 ‑ 10 years, depending on the intensity of traffic. Tredgrip was never intended as heavy duty industrial non skid coating, but rather is an easily applied domestic and commercial type product which is easily applied. Bare foot traffic of children around a pool is where Tredgrip is ideal, not for forklifts up a 45º concrete loading ramp! Tredgrip is very easily repaired in high wear areas on steps, ramps etc.

HOW FAR WILL TREDGRIP GO ?

When Tredgrip is applied in accordance with our recommendations it will cover 6m² / litre 1 coat. We recommend 3 coats, so that on a finished job you will get 2 M² / litre. This variable, depending on porosity and texture of the surface.

HOW LONG WILL IT TAKE TO DRY ?

Tredgrip is applied as a fairly heavy film, and it takes more than an average time to dry. We recommend 3 hours minimum between coats and 72 hours before a surface is subject to traffic. These times can be dramatically shortened if Tredgrip is being applied in an open sunny position of 25ºC with a light breeze blowing. These would be optimum conditions and would dramatically reduce drying times.

CAN TREDGRIP BE APPLIED OVER PAVING PAINT?

Yes, if the paving is sound. If however the paving paint is flaking or cracked, it should be totally removed and started from scratch. By applying a new coat over an old one it will not rejuvenate the adhesion of the old to the substrate.

HOW CAN TREDGRIP BE APPLIED?

We recommend the use of a brush or long nap roller for small areas or a soft synthetic bristle household broom or a wide long nap roller for large areas. Always apply one coat in one direction, then apply the next coat at 90º or right angles to the previous coat. This will give a more pleasant appearance to the finished project. Calculate material usage before commencing a job so that any endeavour to "stretch" the coverage is minimised. Always ensure, that equipment is washed out with plenty of clean water before the Tredgrip dries.

WHAT ARE THE ADVANTAGES?

Tredgrip is not a rigid coating, but is rather a permanently flexible film which will move within the substrate in the process of expansion and contraction.
Because Tredgrip is fairly heavy bodied, it will bridge or fill hairline cracks in concrete, effectively hiding them, then will move with substrate movement.
Due to the high solids content of Tredgrip it has good coverage per square metre making it very cost efficient on a square metre basis.
Tredgrip has a good serviceable life and is easily repairable.
Tredgrip comes in a variety of factory colours and can be tinted to suit almost any decor from white.
