Polymeric sand is appreciated by paver installers because joints you get from it are durable and even . This eliminates any risk of weed growth and ant infestation that could affect the overall aesthetics and durability of paver projects.
Using polymeric sand significantly lessens the chance that weed seeds will get lodged between pavers because there is nowhere for new weeds to take hold. If you do not have polymeric sand as your joint sand, consider replacing the existing sand.
The two main types of sand that are used between paver joints are fine dry sweeping sand and polymeric sand. They are both frequently implemented but do their best work in different types of projects.
Quick and simple to use, Weed Free Paving Sand contains kiln dried sand, with the added benefit of organic inhibitors for long lasting weed suppression. Simply brush into paving joints to help prevent weed growth.
Premium joint sand is the best choice with it comes to refilling and restoring your missing paver joint sand. Compared to polymeric sand, premium joint sand takes less absorption and drying time which makes the restoration process faster and more efficient.
Regular sand for paving is prone to erosion, damage from weeds and can make your pavers hard to wash without risking the loss of any jointing sand between the stones. Using polymeric sand, however, prevents weeds from taking root and holds pavers firmly in place thanks to the durability of its seal.
However, you should NEVER install polymeric sand when it is raining! Rain activates the polymers before the sand is in the joints which will ruin your hardscape by producing a haze and adhering sand grains to the surface of the pavers.
First launched by Techniseal in the early 2000s, polymeric sand is today considered as the ultimate paver jointing material out there!
Specially designed narrow-bladed weeding tools – sometimes called 'dandelion weeders' – for tackling such weeds are the most effective. More generally, a 'block paving knife' can be run along between pavers to sever most weeds. A wire-bristled 'block paving brush' is good at removing moss and the smaller weeds.
In the old days, patio owners were removing old contaminated sands from cracks & sand between pavers in patio or bricks of brick patio. They used to fill up the crevices in stone pavers or brick patio with new or fresh sands between pavers. Unfortunately, it alleviated weed growth only for a limited period of seasons.
In short, no you cannot use regular sand between pavers. You should not use just any sand that you can get a hold of to put in between your paver joints. This will lead to the washout of the pavers and poor vertical interlock which is important to the strength of the interlock pavement system.
Natural sand is a more suitable option than polymeric sand for bedding. Also, it is excellent for people looking for a budget-friendly option.
Instead of simply using regular sand to fill in the missing spots between the pavers, build long-lasting beauty into the surface with polymeric sand. If you don't, much of the sand you put in will wash out after a few heavy rains, and you may see weeds pop through before you finish packing up at the end of the job.
Weeds don't grow from beneath the stones. They grow between the stones when the jointing sand washes away leaving space for the seedlings to fall in. Here in a moist, dark setting, the conditions are right for weeds to germinate and grow. Even a couple seedlings can quickly spread across your patio floor.
Salt leaches into the groundand essentially sterilizes it, preventing vegetative re-growth. Spread a thin layer of rock salt between your walkway's bricks, pavers or stones. It will kill any weeds or grass growing there, and keep them away for years. Apply rock salt to cracks and crevices in your pavement or driveway.

Epic Fail #1: Too much or too little watering.
Using too much water can cause the sand to wash out of the joints. On the contrary, using too little can result in the product not setting up properly. Hazing can also occur if sand residue isn't fully washed off the surface of the pavers.
Any excess polymers and sand should be rinsed off of the project surface. Go over your pavers again with a leaf blower to blow any excess water and sand off of the surface of your pavers. Work in small areas to be sure you remove as much standing water and/or sand as possible.
Polymeric sand is the most popular and useful filler used under brick pavers. It is a mixture of fine sand, adhesive and is most widely used in paver joints. Typically, polymeric sand lasts for up to 10 years. But if you use high-quality polymeric sand, it can last for approximately 15 years.
Paver sand is similar to playground sand, but the granules are mixed with a silica additive to make them more course and binding. As the name suggests, paver sand is often used for leveling pavers in constructing walkways and patios.
