SikaScreed®-330 MetalTop (ID)

Heavy duty high strength iron aggregate topping

SikaScreed®-330 MetalTop (ID) is an iron aggregate topping designed to provide industrial floors with extra heavy-duty protection against abrasion and impact. Applied over prepared hardened concrete it gives significantly longer service life than either normal high strength concrete or natural aggregate toppings.
SikaScreed®-330 MetalTop (ID) has a lower modulus of elasticity than other toppings of equivalent compressive strength which increases Impact resistance and total energy absorbing capacity (toughness).

  • Ease of application – Extended working life at screedable consistency (130 to 180 mm slump) allows ample time to place, float and finish. Rotary com-pactors are not required.
  • Heavy duty, durable industrial floor topping – Formulated to be applied at a thickness of 13 to 40 mm, provides compressive strengths equivalent or superior to no-slump and other toppings.
  • High abrasion resistance – Eight times more wear resistance than plain concrete.
  • Greater toughness – Energy absorbing capacity is significantly greater than normal high strength con-crete or natural aggregate toppings.
  • Increased impact resistance – Four times greater than plain concrete.
  • High density surface – Resists oil and grease pene-tration, reduces dusting and absorption.
  • Easier to clean – Lower maintenance costs.
  • Protects against joint deterioration – Iron armouring eliminates the risk of dangerous protruding or buckled joints from steel tiles, minimises damage to pro-duction goods and increases the life of materials handling equipment.

Overview

Usage

  • Areas subject to heavy abrasive traffic, impact and continuous wear, such as loading docks, aisles, waste transfer facilities, truck or tractor repair areas, and mill scale sluiceways.
  • Areas where safety authorities have deemed other floor surfaces hazardous because of excessive wear, dangerously buckled steel plates, etc.
  • Mining workshops with tracked vehicles.
  • Floors with scraper blades in constant contact.
SikaScreed®-330 MetalTop (ID) is not recommended for areas where steel plate has worn through in less than one year, or where the floor surface is exposed to chemicals that would affect a concrete floor. For applications under these service conditions consult Sika Indonesia about their range of chemical resistant flooring systems, such as Sikafloor® Epoxy Series and Sika® Ucrete® Series.

SikaScreed®-330 MetalTop (ID) + clean water

Compressive strength

1 day

~40 N/mm2
3 days~50 N/mm2
7 days~65 N/mm2
28 days~80 N/mm2

Note : Typical compressive strengths for 50 mm cubes, cured at +21 °C, mixed to the recommended consistency using 2.4 litres of water per 25kg bag.

Reasonable variations from the results shown here may be experienced as a result of jobsite conditions. Mix an entire bag of SikaScreed®-330 MetalTop (ID) when preparing cubes for strength tests.

Application

Layer thickness

13 - 40 mm

Ambient air temperature

+10 °C to +35 °C.

Substrate temperature

+10 °C to +35 °C.

Consumption

2.4 liters of water in 25 kg bag of SikaScreed®-330 MetalTop (ID) and provides 7.7 liters of screedable topping.

Because the depth of surface preparation may vary from design it is best to overestimate the quantity required by 10-20% for the first stages, until actual usage is established.

SUBSTRATE PREPARATION

  • Prepare substrates and remove separation and sinter layers mechanically by selecting and using abrasive blast cleaning, grinding or planing / scarifying equipment for the type of substrate.
  • The final texture of the substrate must be open textured and gripping.
  • Remove weak cementitious and levelling layers. Surface defects such as blow holes and voids must be fully exposed using the surface preparation equipment.
  • Use products from the Sikadur® range of materials to fill cracks. Contact Sika Technical Services for additional information on products for levelling and repairing defects.
  • Use industrial vacuming equipment to remove all dust, loose and friable material from the application surface before applying the product.
  • To improve the adhesion and provide a pore free surface for subsequent coverings, use suitable bonding agent.
  • Used SBR, Acrylic Polymer or Epoxy based bonding agent, depending on traffic conditions.

MIXING

Important:

Do not add more than 2.4 liters of water to 25 kg of powder. Use only drinkable water for mixing.

Important: Do not mix or blend with other binders.

Important:

In case of higher water temperature, the water could be cooled down by using clean ice. Requirement: Use an electric single or double paddle mixer (< 600 rpm) with helical disc-shaped mixing paddle.

  • Pour ~2.4 liters of clean/drinkable water into a clean mixing container.
  • Mix the water slowly while gradually adding the complete bag of powder.
  • Mix continuously for ~3 minutes to achieve a smooth, uniform mix. If necessary, add more water to achieve the required consistency.
  • To allow entrained air to escape and mature.
  • Mix for a further ~15 seconds. Pour the mixed product onto the prepared concrete substrate.

APPLICATION

Please refer to method statement for SikaScreed®-330 MetalTop (ID) for complete application and curing instructions.

CLEANING OF EQUIPMENT

Clean all tools and application equipment with water immediately after use. Hardened material can only be mechanically removed.
