Concrete Panel Mold PM 1020
This mold designed to produce panels that can be mounted vertical or horizontal on wall as wall panels, large format tiles, show walls and large paving stones.
Mold size — 5.40 SQ.FT (0.50 m2). approximate.
Measurements - 41 1/2” X 21 3/4” X 1 1/2” (105 cm X 55 cm X 3.80 cm)
Mold sections — 1
Section dimensions: 39 1/2” X 19 3/4” X 1" (100 cm X 50 cm X 2.5cm)
This mold can be used to cast Concrete Wall Panels or Paving Stones for floor.
PM 1020 Stone-casting Instructions:
Always apply release agent to your mold prior to casting concrete.
PM 1020 mold casting weight is about 45 lbs. (20.44 kg.)
We use this 1:2 cement to filler ratio mix : (you can also mix 1-part Portland cement to 3 parts sand [filler], but plasticizer and water has to be re-calculated by cement weight)
15 lbs (6.81 kg) Portland cement (white for light stone colors, gray for dark stone colors)
30 lbs (13.63 kg) Sand (20-30 mesh recommended. Silica sand or "all-purpose" sand works great)
60.02 oz (1.64 L) Water (We recommend water to be 20%-30% of cement weight.) (If your mix is too liquid, use less water.)
2.4 oz (68.13 g) Super-plasticizer (Superplasticizer's dosage rate is 0.5% -1% of cement weight. We are using 1%)
For best result always add dry pigments to your mix prior to adding the water. Mix concrete with pigment and additives for a few minutes, then add water (mix at least 3-5 minutes). You can also add Super plasticizer to the water 10-15 minutes prior to casting, then mix with dry ingredients.
Please note: Concrete minimum mixing time is 3 minutes (it takes a few minutes until Super Plasticizer absorbs into the cement and start reaction)
To color different molds sections, brush oxide pigment over the selected sections, then cast the concrete.
Cover the mold with plastic while it is curing. Remove the stone from the mold in 12-24 hours.
