THERMOSHIELD – Heat Insulating Mortar is a high quality heat insulating mortar designed for exterior and interior applications over concrete substrates. Thermoshield has exceptional insulating properties compared to regular mortar. It reduces heat absorption, as well as heat transfer by a total of 140% to achieve & maintain a cooler room temperature. Thermoshield also blocks heat & sound, whereas regular mortar allows heat & sound to penetrate walls and ceilings.

How to use Thermoshield – Heat Insulating Mortar

1. Mixing

Use ONLY non-absorbent containers such as plastic pail or a galvanized iron sheet as mixing base. Pour 16L clean water into the mixing base & add 23kg THERMOSHIELD. Stir for 3 – 5 minutes using a mixing torque to attain a lump-free & flowable consistency. Allow mix to stand for 15 minutes and remix briefly before use.

Caution: Use only non-absorptive materials as mixing base (plastic pail or galvanized iron sheets). If absorbent materials such as plywood, wooden box, gypsum board, fiber cement board or cardboard is used, it will affect the chemical properties of the product, which can result in bonding failure & poor product performance. 

2. Application

a. WALL Application – THERMOSHIELD is directly applied on hollow blocks or on a concrete surface using a steel trowel, just like regular mortar.

b. DOUBLE WALL Application – THERMOSHIELD can be applied in between 2 CHB walls by simply pouring the mix into the cavity.

c. ROOF DECK Application – THERMOSHIELD can be applied directly on the concrete slab or after protecting the concrete with cementitious waterproofing.

3. Finishing

For Wall Applications, ZEMCOAT Skimcoat is recommended to be applied on top of THERMOSHIELD after 7 days curing, before applying paint or wallpaper.

For Roof Deck Applications, Aquashield Plus Cementitious Waterproofing must be applied prior to protect and seal THERMOSHIELD. Refer to sectional detail C for proper application.

Note: During the final process of curing, protect the initial and final layers by damp curing with burlap or polyethylene sheets to avoid direct sunlight for 2 days.
