In severely corrosive atmospheres, topcoats may be used for added durability and chemical resistance. consult Carboline Fireproofing Technical Service for selection of the coating most suitable for the operating environment.
Seal Coat - In corrosive environments, use an appropriate topcoat. If topcoating is required, apply Carboguard 1340 as a seal coat. Carboguard 1340 shall be thinned 25% with Carboline Thinner
- 2. Carboguard 1340 may be applied after 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of final application of Pyrocrete 241. Consult Topcoats the Carboguard 1340 Product Data Sheet for minimum and maximum cure times.
Top Coat - Surface hardness should be a minimum Shore DO 64 as measured with a durometer prior to application of the topcoat. Normally, this minimum dry time is 10 days at 70°F (21°C) and 40 days at 40°F (4°C), for thickness of 1 (25.4 mm) or less.
Caulking - For exterior installations, Acrilast caulk should be applied at all termination joints between Pyrocrete 241 and the substrate. Contact Carboline Fireproofing Technical Service for full information.
S U B S T R AT E S & S U R F A C E P R E PA R AT I O N Before applying Pyrocrete 241, the substrate coating must be free of all oil, grease, condensation, General or other contamination.
If primer is required, steel preparation before priming should be done in accordance with the Steel recommended primers product data sheet. Contact Carboline Fireproofing Technical Service for approved primers.
Pyrocrete 241 is usually applied directly over galvanized surface. If priming is required, contact Galvanized Steel Carboline Fireproofing Technical Service for recommendations.
Concrete The recommended primer to seal concrete prior to applying Pyrocrete 241 is Carboguard 1340.
Aluminum, copper and other non-ferrous metals shall be primed with one coat of Carboline's Non-Ferrous Metals Rustbond Penetrating Sealer.
3.4 lb./yd² (1.85 kg/m²) galvanized metal lath, may be pre-bent and tie-wired into place for appropriate design. Optionally, beam furring clips or electrically welded, pneumatic or self-tapping screws or studs, may be used.
Contour Design - 3.4 lb./yd² (1.85 kg/m²) galvanized metal lath wrapped around the flange edges toward the web approximately 11/2 (38 mm). Contour column designs allow the use of 2"x 2" (50.8 mm x 50.8 mm) galvanized or PVC coated hexagonal metal mesh with beam furring clips as an alternate to the 3.4 lb./yd² (1.85 kg/m²) galvanized metal lath. Plastic-nosed corner beads may also be used for better thickness control and aesthetics on flange edges of steel. Please refer to design details. For contour applications on structural members with web span greater than 16 (406 mm) or flange widths greater than 12 (304 mm) refer to the UL Fire Resistance Directory under Coating Materials section.
Lathing & Attachments Boxed Design - 3.4 lb./yd² (1.85 kg/m²) galvanized metal lath wrapped around member spanning the web, overlapped 1 (25.4 mm) and tie-wired on the flange face 12 (304 mm) on center. For large webbed members, additional support for lath may be needed for ease of installation. Plastic-nosed corner beads may also be used for better thickness control and aesthetics.
Tower Skirts and Flat Surfaces - Require that 3.4 lb./yd² (1.85 kg/m²) galvanized metal lath be anchored on 12 to 24 (304 mm to 610 mm) centers depending upon requirements. The lath should overlap and be tie-wired. On tower skirts only, PVC coated mesh can be used in lieu of 3.4 lb./yd² (1.85 kg/m²) galvanized lath. Mesh shall be 2 x 2 (50.8 mm x 50.8 mm) 20 gauge wire coated with PVC as furnished by Carboline.
When ram set or welding is prohibited; a pneumatic fastener may be used. On very large areas, control joints are made by scoring halfway through the thickness of Pyrocrete. This is achieved by using the trowel blade edge or an appropriate scoring tool. A preferred option would be the April 2019 0148 Page 2 of 7

MIXING & THINNING Use a heavy-duty mortar mixer rotating at 40 rpm with rubber tipped blades that will scrape the Mixer sides and bottom of the mixer. A 50 lb. (22.7 kg) bag of Pyrocrete 241 typically requires a mixer volume of 8 ft³ (227 L) minimum and mixer . Do not use pan type mixers.
Target water level: 4.5 gallons (17 liters)
Add 4.5 gallons (+/- 0.5 gallons) of clean, potable water to a mortar mixer with rubber tipped blades. With mixer running slowly, add powder and mix for 5 minutes (10 minutes maximum) until Mixing a homogeneous mortar-like consistency is achieved. Longer mixing times may result in lower densities. Total water must not exceed 5 gallons (19 liters) per 50 lb. (22.7 kg) bag. In cool weather, warm water may be used to enhance application. In hot weather, cold water may be used.

Target wet density:
76 - 82 lb./ft³ (1,217-1,313 kg/m³). Wet density measurements are critical to obtaining correct dry densities. When checking wet densities, use the following procedures:
Equipment needed:
Density
- 1 liter (1000 cc) polyethylene cup
- Scale accurate to 1 gram Determination of Pyrocrete wet density:
- Weigh the empty cup to the nearest gram, then tare the scale.

Pyrocrete 241 PRODUCT DATA SHEET MIXING & THINNING
- Use the spatula to fill the cup completely with mixed material (do not tamp cup).
- Remove the excess material on top by placing the vertical edge of the spatula on the top edge of the cup. Use a sawing motion to level the mixed Pyrocrete material flush with the top of the cup.
- Weigh the filled cup to the nearest gram.
- Record the weight of material in grams. This value equals the wet density in grams/liter and kg/m³
- To calculate the wet density of the material in lb./ft³, multiply the value in grams/liter by 0.0624.
