Koster Aquatecnic provides a long term solution to an Aintree grandstand degradation issue

Aintree Racecourse is located in the Metropolitan Borough of Sefton, Merseyside, England. The racecourse is best known for annually holding the world-famous Grand National steeplechase. The Grand National meeting usually takes place in April over 3 days.

The Lord Daresbury Stand, the oldest grandstand, was in situ when Aintree hosted Formula One races between 1955 and 1962, (1955 being the year that the great Sir Stirling Moss won his first British GP).


The Lord Daresbury Stand provides a bird’s eye view of the Grand National finish line.


The grandstand was suffering badly from water ingress to the areas below due to the floor coatings and joint seals degrading over years of exposure to the elements.

The Jockey Club, who own and run Aintree and other major horse racing courses in the UK needed to resolve these issues and approached Koster Aquatecnic for a solution.

Koster flooring systems were specified to provide a long-term solution to the exposed areas, providing a decorative, slip-resistant finish suitable for UV exposure and the weather conditions faced in the UK.

The chosen Koster BTG system was then specially adapted to meet the desired finish chosen by the Jockey Club for this 715m2 area.

As part of the package of measures it was also decided to refurbish all of the expansion joints, using Koster FS-V polysulphide joint sealant.

Pro-Res (UK) Ltd, a Koster approved applicator, completed the works on site.

The area had to be mechanically cleaned to remove all trace of the previous coating.

The prepared concrete was then primed with Koster CT121 at 400g/m2. This is moisture tolerant, solvent free, epoxy primer, suitable for use in high stress trafficable areas.

The Koster BTG System was then applied. This consists of three items: –

1) Koster EM-VS scratch resistant high-build epoxy applied with a squeegee and back rolled at 300g/m2 per coat.

2) Kiln dried quartz sand graded between 0.4 to 0.8 was broadcast over all standing areas and walkways, to provide a highly non-slip surface.

3) The area was then sealed with a colour tinted version of Koster TS Transparent at 200g/m2 this top layer encapsulates the sand, whilst still allowing the texture to come through. The Koster TS Transparent provides a high level of wear resistance and excellent UV stability.

The completed area is the perfect spot to enjoy the worlds’ biggest horse race in 2021 and beyond.
