What customers have to say about our work

“When I first e-mailed you I got a reply the next day advising me with what to purchase. You also went out of your way to get the grinder I required. You also went out of your way to have a normal conversation by e-mail. It looks like to me that you Paul care about small companies like me even though I live in NEW ZEALAND and also larger ones. Paul you are a credit to your company and may you go on to build it larger as you deserve it.”
Denis Roberts (Manager) New Zealand

"I feel I must tell you that I am over the moon with
the TV50 and C-tec cutting cowl. I used it for the first time today, and was amazed how well it
worked. It's worth its weight in gold. Thanks very much."
Regards Phil Hone.

Hi Paul,
Thank you for the lead.
Spoke to Rob, very happy with the two TV50’s which he purchased from you 10 years ago. We have now supplied him a new motor & head for one of the units the other is still going strong.
Best regards, Jerry”

SPEKTRIN® LITHIUM Concrete Hardener & Sealer

SPEKTRIN® Lithium is a clear penetrating hardener that binds loose friable and porous mineral substrates. Penetrates 4-6 mm and consolidates, hardens and dust-binds. Increases compression strength of the concrete by as much as 25%, and abrasion resistance about 2.5 times why virtually all abrasion dust is eliminated 100%. Will not trigger or contribute to surface ASR (Alkali Silica Reaction). Easy and cost effective to apply. Zero-VOC, non-flammable, no odour, and safe to use.

The treatment is permanent and protects the under-lying substrate from detergents, motor oil, petrol, transmission fluid, solvents, de-icing chemicals and other common chemicals. Increasing the resistance to dirt why it makes cleaning easy.

The very good Sd-Value ensures optimum water vapour permeability why excess moisture can evaporate.


Typical Applications

 Excellent in a wide range of commercial, industrial, agricultural and residential applications. On floors as well as on walls. Including air ports, balconies, basements, bridges, car parks, car washes, concrete bridges, driveways, harbour, parking decks, tunnels and other high traffic areas such as factory floors, storage/distribution areas, warehouses, workshops, etc.

As a quality clear coating which provides superior performance on mineral substrates as concrete, plaster, etc. Also on former lime paints as it converts the surface into a natural hard ceramic-like coating (silicon dioxide). After the reaction it cannot peel or flake from substrate.

As an impregnator whose prime purpose is to provide dust-proofing, resistance to abrasion and freeze-thaw cycles on concrete. For use both indoors and out.

Application Instructions:

Substrates should be firm, free from laitance and clean. The surface must not be coated as product should be used on bare mineral substrates only.

 The surface should be vacuum cleaned followed by thoroughly cleaning with an alkaline cleaner as liquid soap (pH 10). Rinse and allow the surface to dry.

Apply wet-in-wet in a continuous film. Use a microfiber pad to even spread the product. Keep wet for 20 minutes without any dry areas, and avoid puddles . Squeegee off excess materials from the surface. The entire densification process takes 25 minutes.

Should lower water absorption on floors be wanted, use SPEKTRIN SILOXANE that has a  

W-Value of 50 g/m2/h0.5.

Accepts pedestrian floor traffic after 1-2 hours and light vehicles after 24 hours. One effect of the treatment is that smooth concrete will get a soft gloss (shine) as satin, which can be increased by buffing at high speed (> 1000 rpm).


Solids 20%! Industry average is 8%!

Our hardener is in a concentrated form to help reduce shipping costs, prior to use sealer should have water added 1:1 .

 Available 5L and 20L drums - 20L Drum POA


The product has a CE-Marking.

Application rate: Normal surface 5-7 m2/litre.
  Power-floated surface 12-15 m2/litre.
  (depending on porosity)
