What type of mortar should I use to skim boat brick?
Once the brick is suitable for bonding to it, you should use a modified thin-set mortar that at least meets ANSI A118.4 requirements to skim boat the brick substrate. If the brick joints are deeper more than 1/4″ then you have to use a mortar that allows for a thicker application such as a Large and Heavy Thin-set mortar ...
How to test if a brick is bonded to a mortar?
An easy test is to put water on it and see if it readily absorbs. If it does then generally it can be bonded to with a thin-set mortar. If it has a coating or doesn’t readily absorb water then you have to scarify the brick with some type of grinder.
Is A118.1 a modified or non modified mortar?
They use to only recommend ANSI A118.1 non-modified thin-set mortars when installing over their membrane, but now they produce a polymer modified thin-set so they might have changed their mind.. Thanks for the quick reply. They do make 3 new types (one of which is their All-Set, which is a modified).
How long does it take for modified thinset to dry?
When sandwiched between two impervious layers — the tile and the installation membrane — drying can only take place through the open grout joints, which can take as long as 60 days!
Who invented modified thinset?
The Rise of Modified Thinset. To help strengthen thinset, Henry Rothberg invented a synthetic form of latex to be added to the thinset, thereby kickstarting the whole segment of modified thinsets. He took inspiration from modified concrete mixes of the 1920s that were used to repair and strengthen sea walls.
How to mix thinset?
Always add the dry thinset mix to the water — not the other way around. Use a drill fitted with a mixing paddle to mix the thinset. Mix the thinset as if you’re mixing batter. Start slowly so as not to splash the powder or water out of the bucket and stop when it’s the consistency of frosting or peanut butter.

Construction
Types
- There are three main types of grout: cementitious grouts composed of a Portland cement base; epoxy grouts, and furan grouts, with variations available in each type. Cementitious and epoxy grouts are available in different colors that allow you to match or contrast with the color of tiles; furan grouts are usually available only in black.
Products
- Cementitious grouts have as their main component Portland cement, plus filler particles of different sizes, a water-retentive additive, and colored pigments. Cementitious grouts are the traditional grouting material, used most often in residential applications as well as some commercial applications. Cementitious grouts come in a range of colors that let you match or c…
Prevention
- Sanded cementitious grouts include fairly large sand particles that can be seen and feltthey look and feel gritty. Sanded grout is normally recommended when the grout seams are 1/8 inch wide or more, as the sand provides extra bonding power that prevents cracking. Some care is required if using sanded grouts on highly polished tiles, as the sand can actually scratch the surfaces. Testi…
Preparation
- Sanded grouts may be formulated with a latex polymer additive, either included in the dry mix or added in as the grout is mixed with water. The additive enhances the water-proof nature of the grout, and also increases strength.
Variations
- Epoxy grouts come in both unsanded and sanded forms, although the type of sand used is different from that found in cementitious grouts. Epoxy grouts set up fairly fast, making them a little tricky for amateurs. Epoxy grouts are also much more expensive, costing about $8 per pound vs. $1 to $2 for cementitious grouts. But for areas where maximum stain resistance is required, …
Advantages
- One advantage of epoxy grouts is that they don't need to be sealed, as do cementitious grouts. However, they can become stained. Scrubbing with a mixture of bleach and water, or vinegar and water, usually does a good job of cleaning epoxy grouts.
Composition
- Furan grout is similar to epoxy, but it is made of polymers of fortified alcohols that are highly chemical-resistant. The name derives from the fufuryl alcohol included in the formula. There is no water at all used in this type of grout. Furans are two-component systems that contain a furan resin and a filler powder with an acid catalyst. It is the acid catalyst that causes the furan resins …
Usage
- Furan grout is commonly used to grout brick pavers and quarry tile and it is also recommended in areas exposed to chemicals and grease. The tile surfaces may be smooth, non-skid, or abrasive, depending on the intended use for the floor. The tile or brick surfaces must receive a wax coating to protect them from staining prior to the installation of furan. Because of the difficulty of install…
Safety
- Precautions should be made when mixing to avoid breathing the vapors. Special skills are required for proper installation, which must be done when and should be used when temperatures are between 60 degrees and 90 degrees Fahrenheit (70 to 80 degrees is ideal).
Cost
- Cost depends on the level of expertise of the contractor and the area on which the tile grout will be installed. As an average, it is safe to say that the cost can range between $3 to $5 per square foot for grouting, cleanup, and sealing (where required).
