Description
AVCEM Super Latex is based on modified Styrene butadiene latex used for high performance applications in waterproofing and repairs. It is used for repairs of spalled concrete such as – floors: columns, beams, chhajjas, slabs & waterproofing of toilets & bathrooms & terraces.
It bonds strongly to old & new concrete & plaster.
Features & Benefits
Multipurpose – It is multipurpose & economical product, easy to use Cracking – It prevents cracking by improving flexural strength Hardness – Improves the hardness & prevents dust generation Shrinkage – Reduces drying & aging shrinkage cracks
Bonding – Bonds strongly to concrete, masonry, stone work, plasters, steel, asphalt & most of the
building materials.
Erosion & corrosion – Improvers erosion resistance & prevents corrosion. Abrasion resistance – Improves abrasion resistance of cement mix.
• Waterproofing – Prevents leakage & dampness.
• Durability – Enhances strength of a repair mortar & provides durability.
Rebound loss – Less material wastage- material does not fall back/rebound, when used as bonding agent.
Coverage – Excellent Coverage -70-80 sq.ft per kg/ in 2 coats, hence economical.
AREAS OF APPLICATION
As a bond coat – Plaster to plaster, concrete-to-concrete, plaster to concrete masonry to stone work and for plastering over brick masonry. Bonding coat & mortar for tiles & panels, underlays for special finishes such as top rendering coat for chemical resistant floors.
As waterproofing – Waterproofing of small roof terraces, sunken portions of toilet & bathrooms, chajjas & lift pits, balconies & stare cases. Water proofing of liquid & effluent tanks, car deck and walk ways.
As crack repair – Repairs of plaster cracks more than 5 mm & in gaps developed between masonry and RCC members.
As rebar coating – Coating for prevention of corrosion over rebars.
For Cladding – Fixing or refixing of slip bricks, tiles, stones & marble bedding.
As external rendering – Weatherproof & frost resistant render, high wear & erosion resistant render.
As bonding slurry coat for pin hole treatment on concrete surface & as repair mortar for overhead applications.
METHOD OF APPLICATION
1 SURFACE PREPARATION
Clean the surface with wire brush or scrubber to remove hidden dirt, loose particles. Laitance, & dust. Degrease the surface by using suitable solvents
Repair the concrete spalled portion by saw cutting the extreme edges of the repair location to a depth of at least 10 mm to avoid featheredging & to provides strong substrate.
Clean the concrete surface to remove any contamination where breaking. is not possible. Roughen the surface by light scabbling or grit blasting.
Expose corroded rebars in the repairing area fully. Remove all loose scales & corrosion
deposits & immediately clean the surface.
APPLICATION MIXING

APPLICATION |
MIX (SUPER LATEX:
WATER: CEMENT |
METHOD OF APPLICATION |
| 1 | As bond coat | 1:4:7 | Apply a single coat of the mixed quantity of AVCEM Super Latex.
When coat is tacky, apply the plaster or concrete according to the situation. Always add cement to the liquid (AVCEM ‘Super Latex water =1 4). |
| 2 | As waterproof coating | 1:4:7 | Brush apply the 1st coat on brick.
Apply 2nd coat after 1st coat is dry approximately 4-6 hrs between two coats. Overlay the 2nd coat with screed/plaster for protection and finish. |
| 3 | Rebars coating | 1:4:7 | Rusted rebars must be thoroughly scraped, by mechanical means if required.
Brush apply a single coat of prepared mix over the . rebars. Apply concrete/mortar when the coat is tacky. |
| 4 | As waterproof plaster /repair plaster | 50 kg OPC cement,150 kg Sand,1kg Super Latex,20 Itr Water. | Mix 1 kg of AVCEM Latex with pre-measured water for 50 kg of cement.
Use this mix to add to the recommended dry plaster mixes. Plaster mixes may be as rich as 1:3 (cement: sand) Keep water-cement ratio in plaster as low as 0.4 but not more than 0.45. For better application apply a bond coat with super latex as suggested earlier. 2nd and final layer of plaster must not be mixed with super latex. |
| 5 | For ‘salt petre’ – free plaster Brick masonry | 1:4:7 | Brush apply the 1st coat on brick. Apply 2nd coat after 1st coat is dry.
When 2nd coat is tacky. Place plaster as per instruction in no. |
| 6 | Renders, Patching & Crack Repair Mortar | 5 kg AVCEM Super Latex +15 Itr Water +50 kg Cement +150 kg Sand. | Mix 5 kg of AVCEM Latex with pre-measured water for 50 kg of cement.
Use this mix to add to the recommended dry plaster mixes. Mortar mixes may be as rich as 1:3 (cement: sand) Keep water-cement ratio in plaster as low as 0.4 but not more than 0.45. Clean the cracked area properly of all loose materials. Wet the crack completely using a bottle spray. Apply a single coat as a bond coat prior to the crack filling of the AVCEM. Super Latex as per the mixing proportions mentioned earlier. Fill the crack with above prepared mortar. Compact it into the crack fully and trowel finish to level. |
