Fitting encaustic tiles? Full treatment

I have the full treatment set for encaustic tiles as recommended by Fired Earth.

I purchased a small number of Bert & May encaustic tiles for a hearth and had to buy the full recommended kit. This is several rooms worth. 

I have used no more than 15-30ml of each one as only had 20 small tiles.

cost £70. Selling for £45. 

see images. I have the purchase receipt.
