How to make a sample of Dry Crack Filler

Using Consandtrate Dry Concrete Crack Filler

Whether you're just testing the batch you received, or trying to customize between colors, making a sample of crack filler can give perspective on what you're installing in to your concrete.

What you'll need

Dry Concrete Crack Filler from Consandtrate (Natural pigment or stained)
Small petri dish, or bottle cap (something shallow, no more than 1" tall)
Spray bottle, filled with distilled water
Putty knife, or ruler

Making a sample of Dry Crack Filler (DCF)

Make sure the Petri dish you are using is clean and free of debris. Use the spray bottle to mist the dish with a light layer of water. This will give the filler something to bond onto. It's important to mist lightly to prevent over watering. If there is too much water with the filler it can cause hairline cracks.

We're looking to apply in two layers. Initially apply no more than a 1/2" layer of crack filler, it should start to absorb the water instantly. Take this time to determine your ratio of water to sand. The ideal saturation is uniform throughout while being careful not to overwater. If white bubbles begin to form, there is too much water.

Apply the second layer according to the saturation of the first layer. This layer should fill the remaining space in the dish. You want to slightly overfill the dish for when we compact at the end.

(1) If the first layer had too much water, apply another layer of DCF and only add water up until the filler is uniformly saturated.

(2) If the first layer had dry spots, lightly mist the dish again and apply another layer of DCF. Mist with water if not fully saturated.

Take a putty knife, or anything with a flat edge, and compact the DCF into the dish. Start directly on top of the dish, and with the flat edge push down and towards the side. Be careful to try and keep the sample as level as possible. If there is any excess it will flow over the edges and can be scraped off.

Once the sample is compacted it is ready to dry out. Place the dish in a well ventilated area, free from rain or debris, and allow to dry at room temperature for a full 48 hours. It will be dry to touch in 24 hours, and will cure after 48.
