A key advantage of working with Blocksil is that we are always looking at how to take our coatings forward. This may be with new markets or with improvements to the coating itself. A less obvious route is in combining two coatings.
In this video you’ll see our roof coating, Graphene Enhanced Top Coat MT, applied over our new Flame Retardant Coating. The substrate is a thin plastic film. No specific cleaning or preparation process and no primers or adhesion promoters were used. The coating thickness for each coating is less than 500 microns.
In addition to perfect adhesion all the way through, application of a flame doesn’t affect the plastic film.
No flame penetration and no spread of flame. Most impressive.
Blocksil is working with a specialist coatings and paints applicator on fire resistant coatings for remote and inaccessible locations.
The Blocksil Flame Retardant Coating has been chosen as it comfortably protects all substrates, including plastic cabling. The Flame Retardant Coating is an intumescent coating which also prevents the spread of flame.
An intumescent coating is one that chars on the surface when heated by flame. This char is a poor conductor of heat and so helps to suppress and stop the flame. Typically the light char consist of microporous carbonaceous foam formed by a chemical reaction of the coating’s constituents. One such constituent are hydrates. When these hydrates are heated they decompose and water vapour is released, which has a cooling effect. Once the water is spent the insulation characteristics of the remaining coating will slow down heat transfer.
Blocksil donated a transparent coating system to protect the December 2019 Banksy artwork in Birmingham’s Jewellery Quarter.
In this short video you can see one of our operators applying the second coat of the system. The non-toxic, environmentally friendly coating will protect the Banksy from unwanted additions and from weathering.
Here is why you should move away from Silicone roof coatings.
This roof coating is only four years old and had started leaking. During cleaning prior to the Blocksil hybrid roof coating being applied, the old Silicone coating simply fell off at minimal jet wash pressure.
Another advantage of the Blocksil system is that it will bond to Silicone coatings, unlike other non-Silicone roof coating options. Of course, what (if anything) is left of the old Silicone coating has to be fixed and firm.
May 31st, 2019, and our Top Coat MT is fire tested in a flat roof format at BRE.
The coating was tested to BS476-3 and EN13501-5. The video shows part of the surface spread of flame test (part of BE476-3), where a naked flame is put against the coating whilst being heated from above.
The coating did not ignite and there was no spread of flame. Can’t get any better than this.
We carried out an indicative fire test on our overcoatable hybrid roof coating, Top Coat MT.
The coating had been applied to a section of painted steel roof profile. Whilst the Top Coat MT is not an intumescent coating, in this test it behaved like one.
This video was taken at the UK Concrete Show in March 2019, hence the background noise!
The beetroot and vinegar had been left on the Power Floated Concrete Sealer surface overnight. The video shows just how easily the dried beetroot and vinegar are removed off the sealed surface. Unlike the unsealed concrete screed, which is permanently stained.
A demonstration of just how effective Therma-Light is in dissipating heat.
The 3mm thick Therma-Light coating on the steel panel easily copes with the heat from a blow torch.
Mastic X Demonstration. Mastic X is our very high bond strength yet flexible mastic. It requires some 800 Newtons (180 pounds force) to break the bond and will accommodate a movement of ± 70%. Available in 380ml tubes, it is applied like a normal mastic.
Therma-Light demonstration. This is an early sample of the thermal insulation coating Therma-Light. As you can see, the coating easily dissipates the heat from the flame. We are working with a specialist manufacturer to bring this coating to market.
