How to stop weeds growing through block paving

While effective sealing is the best way to stop weeds growing through block paving, don’t assume the job is completed once the block paving is sealed. Ongoing maintenance is necessary to keep your paving in fine form throughout the seasons.

Make sure that traffic is kept off the driveway for 24 hours after sealing and don’t walk on the driveway for four hours, unless the sealer dries before then.

Always test the sealant on an inconspicuous area before applying elsewhere, just in case it has an adverse effect. If you can obtain a small sample before buying to carry this out then so much the better.

Despite their name, all-purpose sealants are actually largely ineffective, offering a one-size fits all approach, as opposed to more targeted tackling of weed growth. Select the sealant that will give you the effect you are looking for: matt, wet look, damp look, low sheen or neutral.

Preparing the Area

Finally, when sealing your block paving, ALWAYS wear appropriate protective clothing and footwear.

After preparing the surface in question, apply one coat, making sure the whole area is saturated – but avoid creating puddles. Start by pouring the sealant out, then use a pile roller or squeegee to roll it out- unless you have a sealant that can be sprayed.

Before you start, make sure to select the right sealant for the specific type of paving you have – concrete or clay. There are a wide range of sealants available and you would be best advised to select one that is specifically suited to your type of paving, to minimise issues from arising.

Choosing the Right Sealant

In terms of cost, you really do get what you pay for. Generally speaking, the more expensive the sealant, the better it will be.

Remember, there is no such thing as a surface that is weed-free , and spraying the area with weed killer – no matter how powerful – is simply not enough.
