Scouting for the Best

grouting

One actually can’t name one product as the finest grout sealer. Based on what you’re using the sealer for, there are a large assortment accessible the market. There are different ones for marble and for granite. Grout varieties include tiling grout, flooring grout, resin grout, non-shrink grout and structural grout.

Tiling grout is often used to fill the spaces between tiles or mosaics, and to secure tile to the floor or wall. Structural grout is often used in reinforced masonry to fill voids in masonry housing reinforcing steel, securing the steel in place and is often pumped under pressure in gaps. Non-shrink grout is used beneath metal bearing plates to ensure a consistent bearing surface between the plate and its sub-floor.

Among the grout sealers that are best are the following:

Sika Grout

SikaGrout GP is a general purpose shrinkage compensated cementitious grout blended with aggregates and admixtures with a similar appearance to concrete.

SikaGrout-212 HP is a mixture of Portland cement, and carefully chosen graded Sika Admixtures and aggregates, enabling it to reach high strengths in brief times, making SikaGrout-212 HP suitable for grouting fixing bolts and anchors or bedding machines in the most demanding of conditions.

SikaGrout UW is a ready to use, cementitious grout that can be used for underwater programs. The grout, when properly combined, will have no essential ‘wash out’ of the cement phase. SikaGrout UW is a mixture of Portland cement, graded and carefully selected aggregates, and Sika admixtures, empowering it to attain exceptional flow, non wash-out characteristics, and high compressive strength. Typical applications include bridges, pylons, slipways and dams.

SikaGrout-HES is a ready mixed, high quality, grout that sets rapidly with high early strengths. A blend of high alumina cement, selected and graded aggregates enables it to achieve high strengths in short time frame.

Sika Grout is classed as a non-shrink grout as per CRD-C 621-81, it has high early strength and good flow characteristics and good thermal and corrosion resistance. SkiaGrout will not corrode iron or steel and will not segregate or bleed once applied. It can be drypacked, rammed, troweled, pumped and poured easily.

Parachem Combextra

Shrinkage compensated cementitious precision grout, Conbextra HF, is supplied as a ready to use dry powder. Adding a controlled quantity of clean water produces a free-flowing precision grout for gap thicknesses up to 125 mm. The low water demand ensures high early strength and long-term durability. Conbextra HF is a mix of Portland cement, ranked fillers and chemical additives which impart managed expansion in the plastic and hardened states. The filler grading minimises segregation and bleeding over a broad variety of application consistencies.

Preparation makes best

Thorough surface preparation and right is vital to realize the high operation qualities of construction grout. All surfaces must be sound, clean and free from dust, oils, ice, grease or Other surface contaminants. Bolt holes and fastener pockets should be free of debris and grime by air blasting. Preferably by mechanical means such as needle gun, grit blasting, grinding etc.

All prepared surfaces must be saturated with water several hours prior to Grouting, ensuring it truly is free of any surface water or pools.
