BURST Add-A-Pak Accelerator

BURST Add-A-Pak Accelerator

 

BURST Add-A-Pak is a powerful additive used to give Portland cement products a BURST of accelerant for faster set times. It can be used to help speed up work times in most any portland cement mortar such as mud beds, masonry mortars, underlayments, thin sets and grouts.

Revive - Grout Stain and Sealer

Revive - Grout Stain and Sealer

 

Revive is a pigmented water-based urethane acrylic grout stain and sealer.

Grout Sealer

Grout Sealer

 

Grout Sealer is a penetrating silicone sealer for new or old portland cement grout.

It is a water-based, silicone resin designed to protect grout surfaces from stains and water. It is also recommended for concrete, porous stone and masonry surfaces.

It quickly penetrates, producing a sub-surface hydrophobic reaction below the surface. It does not change most surfaces, leaving a natural look.

Self Leveling Primer

Self Leveling Primer

 

Self Leveling Primer is an uniquely formulated emulsion that must be applied to all substrates prior to the application of Underlayment Self Leveling.

626 Primer

626 Primer

 

626 Primer is a thin section two-component primer; composed of a modified elastomeric copolymer and cementitious filler powder.

626 Primer provides a water resistant bond coat primer that adheres to most difficult to bond substrates.

The primer is trowel applied and can be installed on practically any form or irregular shape.

101 Overspray Primer

 

101 Overspray Primer is used as a primer and bonding agent for underlayments before the installing of Merkrete's waterproof and crack isolation membranes under ceramic, tile and stone.

101 Overspray Primer reduces porosity factor and increases bond on most of substrates prior to the installation of Merkrete's membranes and adhesives.

150 Latex Additive

150 Latex Additive

 

150 Latex Admixture is a compounded and stabilized latex additive used to improve bond strength, water resistance, compressive strength and other physical properties of cement/ sand mixes as well as grouts. 

442 Tuff Flex Additive

442 Tuff Flex Additive

 

442 Tuff Flex is a compounded and stabilized latex emulsion for use with 700 Premium Set (or a non-modified thin set mortar).

700 Premium Set (or a non-modified thin set) with the addition of 442 Tuff Flex is notched troweled to form a thin mortar bed for the installation of porcelain, granite, quarry tile, glass mosaic, dimensional stone and other hard to bond tiles. When cured, these mortars display excellent physical properties in adhesion, resiliency, water and weather resistance, and exceed ANSI A-118.4 requirements.

Prep Seal - Bonding Agent

Prep Seal - Bonding Agent

 

Prep Seal is a water-based bonding agent formulated to increase bonds between liquid membrane layers.

Prep Seal bonding agent provides a water resistant bond coat that assists in adhering Merkrete liquid membrane coats and thin sets.

The bonding agent is brush, roller or trowel applied and can be installed on practically any form or irregular shape.
