Tennis Court Moss

With the Met Office reporting record amounts of rainfall throughout Winter 2015/16, and temperatures 0.9C above the long-term average, we are seeing unseasonally large sales of Qualgex Biocide.  The temperature and rainfall combination is boosting moss and algae growth across hard surface tennis courts and other hard surfaces.

Qualgex is a moss and algae biocide which is suitable for most hard surfaces including macadam and grit tennis courts.  After extensive trials, Qualgex is the product that we chose for surface treatment.

It is the product that Grimshaw Maintenance use when we are engaged to deep clean hard surface tennis courts.  In Gloucestershire and the surrounding Counties we offer an additional deep cleaning service with our Grime Buster which uses high pressure water and a vacuum system to loosen the dirt in the tennis court matrix before lifting the dirt out.

Qualgex Biocide helps prevent regrowth of moss and algae within the court and whilst large clumps of moss may require a second treatment in order to get the product down to kill the lowest levels of the moss, most smaller moss and algal outbreaks can be hit with one application.  Qualgex is one of the strongest products on the market and is fully registered with the Health & Safety Executive.

All chemicals should only be used in full compliance with their safety instructions and recommendations.

Please contact us to discuss Qualgex Biocide sales and shipping or other Tennis Court Maintenance.

Rugby Post Bargains

Single Rugby Goal Posts

The Six Nations has kicked off, with wins for France and England, losses for Italy and Scotland, and a draw between Wales and Ireland.
Most pundits had Ireland slightly ahead, but the game stagnated in mid-field and no-one could break the line to set up the winning points.

To celebrate the start of the 2016 Six Nations Championship, Grimshaw Sports are running a Rugby Post Promotion.
Harrods Rugby posts are now on offer at fantastic discounted prices for the duration of the Championship.

So if you need posts for your club, school or even your own garden (and we can sell half sets), please look here or give us a ring on 01242 513251 (we also offer a price match service).

Hinged Rugby Posts


Hinged rugby posts are far safer to erect and take down and if you use a Hinged Post Assembly Roller it is even easier.

We recommend using rugby post protectors with all rugby posts but we strongly recommend their use with hinged posts as the hinge mechanism projects beyond the profile of the post.


Cleaning Your Tennis Court With Qualgex



We use Qualgex to treat moss on courts and recommend it with the following advice:

If the moss is thick it will probably need more than one application.

A typical 110’ x 54’ “domestic” court is 552m2, a “club size” 114’ x 56’ is 593m2 or a full size 120’ x 60’ is 670m2.

5L of Qualgex will treat 500m2, so is usually just about enough to treat a domestic court for algae and some moss.

It will work on damp (but best not to be saturated, ie immediately after rain) moss. The moss needs to be actively growing, so we don’t apply it unless the temperature for the day is going to stay above 6°C.

Make sure your equipment is thoroughly rinsed out from any weed killer as it reacts with any glyphosate based weed killer and forms a “goo” that blocks up the sprayer.
